1. Solution Part 1 — Angular SaaS tenant connection string “Save” never sends PUT

Why the PUT may be skipped

• The SaaS Angular UI only enables the Save action when:
  • The form is valid.
  • The connection string check has succeeded for the current “Default” connection.
  • The value is actually changed compared to the loaded value.
• The modal manages one “Default” connection string entry. Arbitrary names (like “Financial”) are not supported by the built-in UI. If a tenant has only a non-Default entry in the database, the UI will not bind it and Save may remain disabled (thus no PUT).
• If you customized encryption or altered the DTO without reflecting the UI state (e.g., Check succeeded on a different temporary value but the bound control is unchanged), the UI may consider there is “no change” and skip PUT.
• If you do not have the “ManageConnectionStrings” permission in the browser session (e.g., token mismatch, stale claims), the Save button is disabled and no PUT is issued.

Definitive checks and fixes

• Use “Default” as the connection name when working with the built-in SaaS Tenants modal. The Angular UI expects only “Default” for the editable field.
• Ensure the form control value actually changes before saving. Type or paste the final connection string into the Default field and click Test, then Save.
• Verify the permission in the current session: AbpSaas.Tenants.ManageConnectionStrings. If you recently granted the permission, re-login to refresh claims.
• Confirm there is no validation error on the modal: the UI will not submit if the form is invalid.
• If you previously stored a differently named connection string (e.g., “Financial”), migrate it to “Default” for the built-in modal, or extend the UI (custom component) to manage multiple named connection strings and call PUT /api/saas/tenants/{id}/connection-strings with your own payload.
• If you encrypt connection strings on the client or server, make sure the value bound to the input is the same one that passed CheckConnectionString and is considered “dirty” so the Save button becomes enabled.

Server-side note for encrypted scenarios (ABP ≥ 7.0 validates connection strings):

• The SaaS module validates connection strings before saving. If you store encrypted values, replace the default IConnectionStringChecker (or override the TenantAppService’s internal check) to decrypt before validation:

[Dependency(ReplaceServices = true)]
  [ExposeServices(typeof(IConnectionStringChecker))]
  public class EncryptedConnectionStringChecker
      : SqlServerConnectionStringChecker, IConnectionStringChecker, ITransientDependency
  {
      private readonly IStringEncryptionService _encryption;

      public EncryptedConnectionStringChecker(IStringEncryptionService encryption)
      {
          _encryption = encryption;
      }

      public override async Task<AbpConnectionStringCheckResult> CheckAsync(string connectionString)
      {
          var decrypted = _encryption.Decrypt(connectionString);
          return await base.CheckAsync(decrypted);
      }
  }

• This guarantees that the server “Test connection” endpoint and the save pipeline both succeed when values are encrypted at rest.

Part 2 — SQL Server remote/named instance support and formats

What ABP supports

• ABP uses ADO.NET/EF Core providers. It fully supports remote SQL Server hosts, named instances, and custom ports. There is no localhost limitation in ABP.

Recommended connection string formats

• Named instance (SQL Browser enabled):
  • Server=45.xxx.xxx.xxx\InstanceName;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
  • The SQL client will query SQL Browser (UDP 1434) to resolve the dynamic port.
• SQL Browser disabled or firewalled:
  • You must specify the port explicitly (no backslash instance in practice):
  • Server=45.xxx.xxx.xxx,14330;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
  • If you still want to keep InstanceName for clarity, it won’t be used to resolve the port without SQL Browser; the port takes precedence.
• Default instance on a custom port:
  • Server=45.xxx.xxx.xxx,PortNumber;Database=...;...

Behavior expectations

• With Server=IP\InstanceName:
  • If SQL Browser is reachable, resolution to the instance’s port is automatic.
  • If SQL Browser is not reachable, the connection will fail unless you use the explicit port form Server=IP,Port.
• ABP’s CheckConnectionString endpoint does not add any special logic for instance resolution; it relies on the provider. If a manual port is needed in your environment, use the comma + port format.
• Known limitations: none ABP-specific regarding remote or named instances. Connectivity issues generally come from SQL Browser disabled, firewall rules, or TCP/IP protocol not enabled on the SQL Server.

Actionable guidance for your case

• Prefer the simplest working format for production stability:
  • If SQL Browser is disabled: Server=45.xxx.xxx.xxx,14330;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
  • If SQL Browser is enabled and allowed: Server=45.xxx.xxx.xxx\SQLEXPRESS2014;Database=Financial;User Id=...;Password=...;TrustServerCertificate=True;
• Keep using the “Default” connection name in the SaaS modal.
• Since CheckConnectionString already returns true, focus on ensuring:
  • The UI field is “Default”, changed and valid, then Save should send PUT.
  • If you store encrypted values, replace IConnectionStringChecker to decrypt before validation as shown above so both Test and Save paths succeed.

1. Solution

• ABP does not audit GET requests by default (IsEnabledForGetRequests = false). The [Audited] attribute on controller actions does not override this default for HTTP request auditing.
• To enable auditing for only specific GET endpoints without turning it on globally, create a custom IAuditingMiddlewareMatcherContributor that returns true only for the endpoints you want to audit.

Code example:

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Routing;
using Volo.Abp.Auditing;

public class SelectiveGetAuditingMatcher : IAuditingMiddlewareMatcherContributor
{
    public void Contribute(AuditingMiddlewareMatchingContext context)
    {
        var httpContext = context.HttpContext;

        // Skip non-HTTP GET requests
        if (!HttpMethods.IsGet(httpContext.Request.Method))
        {
            return;
        }

        // If endpoint metadata contains [DisableAuditing], skip.
        var endpoint = httpContext.GetEndpoint();
        if (endpoint?.Metadata?.GetMetadata<DisableAuditingAttribute>() != null)
        {
            return;
        }

        // Example 1: match by route template (controller/action)
        var routeData = httpContext.GetRouteData();
        var controller = routeData?.Values["controller"]?.ToString();
        var action = routeData?.Values["action"]?.ToString();

        // Only audit specific GET actions:
        if ((controller, action) is ("Orders", "GetDetails") or ("Reports", "GetMonthly"))
        {
            context.Matches = true; // audit this request
            return;
        }

        // Example 2 (optional): match by path prefix
        // if (httpContext.Request.Path.StartsWithSegments("/api/my-important-read"))
        // {
        //     context.Matches = true;
        // }
    }
}

Register the contributor and keep IsEnabledForGetRequests = false:

public override void ConfigureServices(ServiceConfigurationContext context)
{
    Configure<AbpAuditingOptions>(options =>
    {
        options.IsEnabledForGetRequests = false; // keep default
        options.AlwaysLogOnException = true;     // still log failures

        // Add our selective matcher contributor
        options.Middlewares.Add(new AuditingMiddlewareConfiguration
        {
            Contributors =
            {
                new AuditingMiddlewareContributor(typeof(SelectiveGetAuditingMatcher))
            }
        });
    });
}

Notes:

• This solution audits only the GET endpoints you decide, with no logging code inside actions.
• You can refine matching logic by:
  • Path patterns, route names, endpoint metadata, or custom attributes you define.
  • You can also place [DisableAuditing] on any GET action you never want audited as an extra safeguard.
• IgnoredUrls is the inverse tool (exclude). Here you don’t need it since you aren’t enabling GET globally.

1. Solution This is a known bug in ABP Studio 2.1.0 when creating a New Module → Microservice on an existing Microservice solution. The wizard crashes with NullReferenceException in NewModuleTemplateAdditionalOptionsWizardPageViewModel.BeforeNextPageAsync on the “Additional Options” step.

Workarounds you can apply immediately:

• Uncheck “Install into the main application” on the Additional Options step and continue. After the module is created, you can manually install it to the related apps (AuthServer, WebGateway, etc.) by:
  • Adding project references (Application, HttpApi, HttpApi.Host, EntityFrameworkCore).
  • Registering the module in DependsOn of the target host modules.
  • Updating the solution’s Helm/K8s and runner profiles if you use them.
• Or, create the service via ABP Studio CLI, then refresh the solution in Studio:
  1. Open a terminal at the solution root.
  2. Run: abp generate-module MyCompany.MyNewService -t microservice
  3. Back in ABP Studio, right-click the solution in Solution Explorer → Analyze → Reload Solution (or close/open Studio).
  4. If you need tests, create them by re-running the command with the related flags or add test projects manually and reference the module.

Notes:

• After generating the new microservice, run database migrations for that service (if EF Core is selected in the template).
• If you use K8s integration, add a Helm chart for the new service or copy an existing service’s chart and adjust values.
• If you keep “Unit/Integration Test Projects” checked, the generation still works; the crash is tied to the automatic “Install into the main application” path in 2.1.0.

Status:

• The crash originates from the AdditionalOptions validation path in the New Module wizard for microservice template and has been fixed and queued for a Studio patch release. Until then, use one of the above workarounds.

1. Solution

• This is not an intended ABP behavior. ABP Angular apps are standard Angular SPAs; resizing should not navigate or reload. We tested ABP Account’s manage page behavior internally in recent versions and found no route reload on resize.
• Most common real cause in ABP Angular projects: the theme/layout swaps markup at breakpoints using structural directives that destroy and recreate parts of the page (e.g., a container with *ngIf tied to screen size or BreakpointObserver), which rebuilds child components and clears form state. ABP’s Lepton/LeptonX themes are responsive via CSS; they don’t intentionally navigate on resize. If your /account/manage loses state, something is causing a component tree teardown on resize.

Try these, in order:

1. Ensure router isn’t reloading on same URL

• In your app’s RouterModule.forRoot, set onSameUrlNavigation to 'ignore' (default) and confirm no code calls router.navigate on resize/breakpoint.

RouterModule.forRoot(routes, { onSameUrlNavigation: 'ignore' })

2. Eliminate structural swaps on breakpoints around the form

• Do not wrap the manage profile tab content or the form component with breakpoint-driven *ngIf/*ngSwitch. Prefer CSS classes (Lepton/LeptonX responsive utilities or Bootstrap grid) to adapt layout without destroying the component.
• If you must swap templates between desktop/mobile, hoist the FormGroup into a service so the same instance survives subtree re-creation:

@Injectable({ providedIn: 'root' })
  export class ManageProfileFormState {
    form = this.fb.group({
      userName: [''],
      email: [''],
      name: [''],
      surname: [''],
      phoneNumber: [''],
    });
    constructor(private fb: FormBuilder) {}
  }

  @Component({ /* account manage tab component */ })
  export class PersonalInfoTabComponent {
    form = this.state.form;
    constructor(private state: ManageProfileFormState) {}
  }

3. Check breakpoint and layout observers

• If using BreakpointObserver or window:resize HostListeners, make sure there is no router.navigate, window.location change, or programmatic tab reset when screen size changes.

4. Verify with a fresh template

• Create a clean ABP 9.0.x Angular solution and test /account/manage. If it does not reproduce there, diff your layout and theme customizations to locate a breakpoint-driven structural change.

5. If you replaced Account components/tabs

• Customizations using ManageProfileTabsService or component replacement should not navigate on resize. Review the replacement component’s template for breakpoint-driven *ngIf and follow step 2 above.

This response was generated by AI. If it didn’t solve your problem, feel free to post a new answer — our support team will jump in to help you soon.

1. Solution

• What you observe is not an ABP feature. ABP Angular apps are standard Angular SPAs. Resizing the browser (switching between desktop/mobile widths) should not reload the route or recreate your page component by itself. If your form loses state, it’s typically caused by one of these in your Angular app:

  1. A full page reload on resize (window.location change).
  2. Angular Router navigation on resize (e.g., navigating to the same URL which reinitializes the component when onSameUrlNavigation is set to 'reload').
  3. Conditional templates/layout swaps at breakpoints that destroy and recreate the component subtree holding your form.

• How to fix:

  • Ensure no global resize handler is causing reload:

// app.component.ts (or any global service)
    @HostListener('window:resize', ['$event'])
    onResize() {
      // Do NOT call location.reload() or window.location.href changes here.
      // Do NOT call router.navigate(...) here just for responsive behavior.
    }

• Check router configuration to avoid reloading on same URL:
  • If you have configured the Angular Router with onSameUrlNavigation: 'reload', set it to 'ignore' unless you explicitly need reloads:

RouterModule.forRoot(routes, { onSameUrlNavigation: 'ignore' })

  Reference: Angular Router docs for onSameUrlNavigation.

• Avoid destroying your form component during responsive changes:
  • Do not conditionally render the whole form component with structural directives tied to screen size (e.g., *ngIf with a breakpoint flag). That destroys and recreates the component, resetting the form.
  • Prefer CSS-only responsiveness (Bootstrap/Lepton/LeptonX classes) or use style/class bindings instead of toggling component existence.
  • If you must swap views, keep the FormGroup in a parent component/service so state is preserved:

// Keep form in a service to preserve state across template swaps
      @Injectable({ providedIn: 'root' })
      export class MyFormState {
        form = this.fb.group({ name: [''], /* ... */ });
        constructor(private fb: FormBuilder) {}
      }

      @Component({...})
      export class MyPageComponent {
        form = this.state.form; // bind same instance
        constructor(private state: MyFormState) {}
      }

• Make sure no breakpoint observer or theme code triggers navigation:

  • If you use BreakpointObserver or similar, ensure you don’t call router.navigate on breakpoint changes unless necessary.

• Quick checklist:

  • Search the Angular codebase for: location.reload, window.location, router.navigate inside resize/breakpoint logic.
  • Verify RouterModule config (onSameUrlNavigation).
  • Replace breakpoint-driven *ngIf around the whole form with CSS or keep a shared FormGroup instance.

1. Solution You don’t need a reverse proxy to serve your HttpApi.Host under /api/auth, but you must consistently set a PathBase and align ALL generated URLs, route prefixes, and Swagger paths with it.

Goal: https://localhost:44320/api/auth should be the app’s base URL. Key rule: When you use app.UsePathBase("/api/auth"), every incoming request path and every generated URL must include /api/auth.

Apply these steps to your HttpApi.Host:

• Set PathBase early in the pipeline

public override void OnApplicationInitialization(ApplicationInitializationContext context)
  {
      var app = context.GetApplicationBuilder();

      app.UsePathBase("/api/auth");

      app.UseRouting();
      app.UseStaticFiles();
      app.UseAbpStudioLink();
      app.UseAbpSecurityHeaders();
      app.UseCors();
      app.UseAuthentication();

      if (MultiTenancyConsts.IsEnabled)
      {
          app.UseMultiTenancy();
      }

      app.UseUnitOfWork();
      app.UseDynamicClaims();
      app.UseAuthorization();

      app.UseSwagger();

      app.UseAbpSwaggerUI(options =>
      {
          // Swagger endpoint MUST include the PathBase prefix
          options.SwaggerEndpoint("/api/auth/swagger/v1/swagger.json", "API");
          // And make Swagger UI itself available under /api/auth/swagger
          options.RoutePrefix = "api/auth/swagger";
      });

      app.UseConfiguredEndpoints();
  }

• Make the app’s own “self” URL include the PathBase In your appsettings.json of HttpApi.Host:

{
    "App": {
      "SelfUrl": "https://localhost:44320/api/auth"
    }
  }

ABP uses App:SelfUrl for various generated links. If you keep it without the prefix, some URLs will be wrong.

• Keep controller routes as-is You do NOT need to change [Route("api/...")] attributes or conventional controller prefixes. PathBase sits in front of the entire app, so /api/auth/api/values would be wrong. Correct request is /api/auth/api/values, which is “/api/auth” (PathBase) + “/api/values” (your controller route). Don’t double-prefix routes.

• Swagger JSON endpoint path With PathBase, the JSON is served at /api/auth/swagger/v1/swagger.json. Ensure:

  • app.UseSwagger() is after UsePathBase.
  • SwaggerEndpoint uses the full path including /api/auth.
  • If you view Swagger UI at https://localhost:44320/api/auth/swagger, the UI can fetch /api/auth/swagger/v1/swagger.json.

• Anti-forgery and ABP Swagger UI script ABP’s Swagger integration injects abp.js to handle CSRF. With PathBase, the SetCsrfCookie endpoint will resolve correctly as long as App:SelfUrl and PathBase are consistent and the Swagger UI page is under the same PathBase.

• If you also expose static assets under the same site Call app.UseStaticFiles() after UsePathBase so static files are served via /api/auth/… when requested from this host.

• Common pitfalls that cause 404 in Swagger:

  • PathBase set but SwaggerEndpoint missing the prefix. Correct: options.SwaggerEndpoint("/api/auth/swagger/v1/swagger.json", ...).
  • Setting RoutePrefix to “swagger” while PathBase is “/api/auth”, then browsing https://localhost:44320/swagger (wrong). With RoutePrefix = "api/auth/swagger", browse https://localhost:44320/api/auth/swagger.
  • Changing controller route prefixes to include “auth” while also using PathBase, which doubles the segment.

Optional (only if you must run the UI at root /swagger while API is under /api/auth):

• Keep PathBase("/api/auth").
• Set options.RoutePrefix = "swagger" and options.SwaggerEndpoint("/api/auth/swagger/v1/swagger.json", ...).
• You will browse Swagger at https://localhost:44320/swagger, but the JSON still resolves under /api/auth/… This is valid if you prefer Swagger at root.

1. Solution ABP uses ASP.NET Core logging with Serilog pre-configured in the startup templates. By default:

• Where to see logs during development

  • Console: visible in the HttpApi.Host output (dotnet run or VS output).
  • File: Serilog writes rolling files under a Logs folder in the host’s content root. Typical path:
    • src/YourProject.HttpApi.Host/Logs/logs-<date>.txt
    • If IIS Express is used, the content root may be under the IISExpress working directory; prefer dotnet run to keep logs under the project folder.

• How to confirm or change the file location

  • Check appsettings.json (and appsettings.Development.json) in HttpApi.Host for Serilog configuration. The File sink path (or rolling file) controls where logs are written. Example keys:
    • "Serilog": { "WriteTo": [ { "Name": "File", "Args": { "path": "Logs/logs.txt", ... } }, ... ] }
  • Adjust path to an absolute or relative directory of your choice and restart the host.

• Increasing verbosity to capture errors

  • In appsettings.Development.json, set MinimumLevel and per-source overrides, e.g.:
    • "Serilog": { "MinimumLevel": { "Default": "Information", "Override": { "Microsoft": "Warning", "Volo": "Debug" } } }
  • Restart the host to apply.

• Production recommendations

  • ABP recommends using a durable sink (e.g., Elasticsearch, Seq, database) instead of plain files in production. Add/change Serilog sinks in appsettings.json and deploy with appropriate volumes/paths.

• Quick checklist

  • Run HttpApi.Host with dotnet run and reproduce the issue; check Console and Logs folder.
  • Verify Serilog:WriteTo section exists in HttpApi.Host appsettings(.Development).json.
  • If no Logs folder appears, ensure the File/Async sinks are configured and the process has write permission to the folder.

1. Solution Here’s the definitive and current way to regenerate Angular client-side proxies for your new application services.

• Where to run the command

  • Run from the Angular app root folder (the folder that contains package.json), not from the solution root.
  • Ensure the backend (HttpApi.Host) is running and reachable while generating.

• The command to use (Angular)

  • Basic (auto-detects the default API endpoint exposed by the running backend): abp generate-proxy -t ng
  • If your API is not reachable via the default discovery URL, specify the backend URL explicitly: abp generate-proxy -t ng -u https://localhost:44367
  • For modular/advanced scenarios, you can target a specific module via: abp generate-proxy -t ng -m MyCompany.MyModule -u https://localhost:44367

• Prerequisites and configuration that affect detection

  • Backend must run (prefer dotnet run instead of VS IIS Express when generating).
  • Angular app should have:
    • @abp/ng.schematics in devDependencies.
    • environment.apis.default.url correctly pointing to your backend URL (commonly your HttpApi.Host).
    • environment.apis.default.rootNamespace set to your solution’s root namespace (prevents deep folder nesting).
    • tsconfig path mappings for @proxy and @proxy/* if you want nice imports.

• Forcing regeneration or when new endpoints are not detected

  • Make sure your new app services are exposed by auto API controllers (Application services derived from ApplicationService are auto-exposed unless explicitly disabled).
  • Restart the backend so the contract endpoint reflects new services.
  • Clear generated proxies if needed (delete src/app/proxy) and run: abp generate-proxy -t ng -u https://localhost:44367
  • If using multiple APIs or different API names, add/verify the apiName in the generated services (defaults to "Default") and ensure the backend’s remote service name matches (Configure<AbpRemoteServiceOptions> if customized).

• Notes for reliable results

  • Keep ABP CLI up-to-date: dotnet tool update -g Volo.Abp.Cli
  • If you run into Visual Studio/IIS Express limitations, stop it and run HttpApi.Host with dotnet run, then generate again.
  • If the Angular project cannot reach the backend during generation (network/port mismatch), the generator won’t see new endpoints—always verify the URL and port with -u.

1. Solution Below is a complete checklist to make ABP’s initialization deterministic again (Swagger/UI visible, OpenIddict client present, admin user created). It focuses on ensuring the Db connection is correct, migrations are applied, and that data seeding is always executed and not skipped.

A) Always run migrations + seed via DbMigrator first

• Set the DbMigrator project as startup and run it. It will:
  • Apply all EF Core migrations for all modules.
  • Execute all IDataSeedContributors (creates default admin user, roles, OpenIddict clients like Swagger/Angular).
• If you frequently drop and recreate the DB, always re-run DbMigrator before running the API host.

B) Verify the connection string used by all processes

• Ensure the same ConnectionStrings:Default is used by:
  • DbMigrator
  • HttpApi.Host (and AuthServer if separated)
• A common cause of “seeding sometimes works”: DbMigrator seeds one database, but the API points to another (e.g., appsettings.Development.json vs appsettings.json or User Secrets). Align these and restart.

C) Ensure seeding is invoked if you rely on hosts (not only DbMigrator)

• In some solutions, hosts do not seed by default. If you expect seeding on API start (not recommended for prod), explicitly invoke IDataSeeder once:

public override async Task OnApplicationInitializationAsync(ApplicationInitializationContext context)
  {
      var seeder = context.ServiceProvider.GetRequiredService<IDataSeeder>();
      await seeder.SeedAsync(); // idempotent; safe to call
  }

• Prefer DbMigrator for consistent results; only use the above during local dev if needed.

D) Confirm your IDataSeedContributor discovery

• Each custom contributor must be in a loaded module and registered as:

public class MyDataSeedContributor : IDataSeedContributor, ITransientDependency
  {
      public async Task SeedAsync(DataSeedContext context)
      {
          // idempotent seeding
      }
  }

• If a contributor is in a project that the host/DbMigrator doesn’t depend on, it won’t run. Add the module dependency to the host/DbMigrator module via [DependsOn(...)]. This is a common reason for “admin not created/client not seeded.”

E) Check OpenIddict client seeding inputs

• ABP Commercial templates seed OpenIddict applications (clients) from configuration. Verify your seeder reads from the correct section (e.g., "OpenIddict:Clients" or similar) and that your appsettings in DbMigrator contains:
  • Swagger client
  • Angular/SPA client
  • Correct RootUrl/RedirectUris for your current ports
• After DB recreate, if ClientId missing arises, it typically means OpenIddict seeder didn’t run or read empty values from configuration. Keep client config in the DbMigrator appsettings.json and re-run.

F) Ensure migrations include all module tables

• If logs show “Invalid object name 'Abp...'” it means migrations weren’t applied (or the wrong DB is used).
• Re-run DbMigrator and check logs for success.
• If you added optional/pro modules, ensure the corresponding EFCore modules are referenced and included in DbMigrator so their migrations are applied.

G) Swagger/Angular UI missing on API

• Confirm you didn’t accidentally disable the middleware:

app.UseAbpSwaggerUI(options =>
  {
      options.SwaggerEndpoint("/swagger/v1/swagger.json", "My API");
  });

• Ensure environment is Development or your code doesn’t conditionally skip UseAbpSwaggerUI in non-dev.
• If ports changed, update Angular environment oAuthConfig (issuer, redirectUri, clientId/scope) to match OpenIddict client entries and API SelfUrl/CORS/RedirectAllowedUrls in HttpApi.Host appsettings.

H) Make seeding resilient and repeatable

• Implement seeding idempotently (check existence before insert).
• Use DataSeedContext correctly (host vs tenant). If multi-tenancy is on and you expect tenant data, seed per-tenant in DbMigrator by iterating tenants and calling IDataSeeder.SeedAsync(new DataSeedContext(tenantId)).

I) Quick local recovery steps

1. Stop API/Auth.
2. Drop database.
3. Ensure DbMigrator appsettings.json has:
   • Correct ConnectionStrings:Default.
   • OpenIddict client config sections (Swagger/Angular).
4. Run DbMigrator once. Confirm in DB:
   • Users table has admin.
   • OpenIddictApplications has SPA/Swagger clients.
5. Run HttpApi.Host. Visit /swagger and login via Angular.
6. If “ClientId missing” persists, verify that the exact ClientId in Angular environment matches the ClientId seeded into OpenIddictApplications and that RedirectUris match the current Angular url (http/https, port).

1. Solution Based on your screenshot and the “Http failure response for https://localhost:xxxxx/api/abp/application-configuration?includeLocalizationResources=false” message in the Angular tab while HttpApiHost is stuck on “Starting…”, the Angular app can’t reach a healthy backend. In ABP Angular, the first call is always to /api/abp/application-configuration; if it fails, the UI shows that error.

Apply the checklist below exactly in this order:

• Trust and use HTTPS dev certificate

  • Run in a terminal:
    • dotnet dev-certs https --trust
  • Close and reopen ABP Studio, then start the solution again.

• Ensure the HttpApiHost really runs and listens

  • In ABP Studio’s Logs pane for Acme.BookStore.HttpApiHost, look for “Now listening on: https://localhost:PORT” and “Application started.”
  • If it keeps stopping:
    • Check appsettings.json ConnectionStrings:Default points to a reachable SQL Server.
    • If first run, the database may be missing. Run the DbMigrator project once to create/seed the DB, then start HttpApiHost again.

• Fix ports in Angular environment

  • Open angular/src/environments/environment.ts and verify:
    • environment.oAuthConfig.issuer = "https://localhost:{HttpApiHostHttpsPort}"
    • environment.apis.default.url = "https://localhost:{HttpApiHostHttpsPort}"
  • The port must match the HTTPS port printed by HttpApiHost at startup.

• Enable CORS for Angular origin

  • In HttpApiHost appsettings.json under App:
    • Add Angular dev origin to CorsOrigins and RedirectAllowedUrls: "App": { "SelfUrl": "https://localhost:{HttpApiHostHttpsPort}", "ClientUrl": "http://localhost:4200", "CorsOrigins": "http://localhost:4200", "RedirectAllowedUrls": "http://localhost:4200" }
  • Restart HttpApiHost.

• Use HTTPS in Angular OAuth config

  • For default templates requireHttps is true. Keep HTTPS and ensure your dev certificate is trusted:
    • oAuthConfig.requireHttps: true
    • issuer uses https, not http.

• Clear stale Angular dev state

  • In the angular folder:
    • yarn (or npm install)
    • yarn start
  • If still failing, clear browser cache and try again.

• Confirm application-configuration endpoint manually

  • Open the browser to:
    • https://localhost:{HttpApiHostHttpsPort}/api/abp/application-configuration?includeLocalizationResources=false
  • If you don’t get a JSON response (200), check HttpApiHost logs for the exception (connection string, migrations, or certificate issues).

Most common root causes for exactly this symptom:

• Missing DB/migrations: run DbMigrator first.
• Mismatched ports between Angular environment and HttpApiHost.
• Untrusted HTTPS dev cert (especially on a fresh machine).
• Missing CORS entries for http://localhost:4200.
