Answer

To obtain a JWT token from an ABP-based application, you typically use the /connect/token endpoint, which is provided by IdentityServer or OpenIddict in ABP solutions. The endpoint expects a POST request with the appropriate parameters, such as grant_type, client_id, client_secret, username, password, and scope.

Example request (using Resource Owner Password Credentials flow):

POST https://<your-abp-app>/connect/token
Content-Type: application/x-www-form-urlencoded

grant_type=password
&client_id=YourClientId
&client_secret=YourClientSecret
&username=admin
&password=YourPassword
&scope=YourApiScope

Replace the placeholders with your actual values. The response will include an access_token if the credentials are valid.

If you are using a development environment, make sure your API is running and accessible at the specified URL. Also, ensure that the client is configured in your IdentityServer/OpenIddict settings.

  • A 400 Bad Request error during Swagger authorization in ABP (especially when hosted on Azure App Service) is often caused by a mismatch or misconfiguration in the OAuth/OpenId Connect client settings, particularly the redirect URI.

To resolve this:

  1. Check Redirect URI Configuration

    • Ensure the redirect URI registered for your Swagger client in the IdentityServer/OpenIddict configuration matches exactly with the URI used by Swagger UI in Azure.
    • For example, if your Swagger UI is at https://your-app.azurewebsites.net/swagger/oauth2-redirect.html, this exact URI must be registered as a valid redirect URI for the Swagger client.
  2. Update Client Settings

    • Update the client configuration in your DbMigrator's appsettings.json and/or in your database (OpenIddict/IdentityServer client table) to include the correct redirect URI.
    • After updating, clear any distributed cache (e.g., Redis) if used.
  3. Remove Client Secret for Swagger

    • Swagger is a public client and should not require a client secret. Remove the client secret from the Swagger client configuration.
  4. Restart Services

    • After making changes, restart your API and ensure the changes are applied.
  5. Verify with Correct URL

    • Access Swagger at the deployed Azure URL and attempt authorization again.

Example configuration for Swagger client in appsettings.json:

"Swagger": {
  "ClientId": "YourApp_Swagger",
  "RootUrl": "https://your-app.azurewebsites.net"
}

And in your client seeding logic:

await CreateClientAsync(
  name: "YourApp_Swagger",
  grantTypes: new[] { "authorization_code" },
  requireClientSecret: false,
  redirectUri: "https://your-app.azurewebsites.net/swagger/oauth2-redirect.html",
  corsOrigins: new[] { "https://your-app.azurewebsites.net" }
);

If you still encounter issues, double-check that the redirect URI in the error message matches exactly with what is registered.

  • Since you are using the new ABP Global Assets bundling system for Blazor WASM, and your logs confirm that both FontAwesome and Bootstrap Icons CSS files are being bundled and minified, the most common cause for icons not displaying (showing as empty squares or boxes) is that the font files themselves are not being copied or served correctly.

  • In ABP's new bundling system, CSS files that reference fonts (like FontAwesome or Bootstrap Icons) use relative URLs to load font files (e.g., .woff2, .ttf). If these font files are not present in the output (wwwroot/_content/...) or not mapped correctly, the icons will not render.

  • To resolve this, ensure the following:

    1. The font files for FontAwesome and Bootstrap Icons are present in your published output under the correct _content paths.
    2. Your bundling configuration (BundleContributor) does not exclude or miss the font file folders.
    3. The wwwroot/_content/Volo.Abp.AspNetCore.Components.WebAssembly.Theming/libs/fontawesome/webfonts/ and similar folders for Bootstrap Icons exist and contain the .woff2, .woff, .ttf files.
    4. The URLs in the bundled CSS (e.g., url('../webfonts/fa-solid-900.woff2')) resolve correctly in the browser (check the Network tab for 404s).
  • If the font files are missing, you may need to update your abp.resourcemapping.js or ensure your nuget packages are up to date and not excluded from publish.

  • You can also try running abp install-libs to ensure all static assets are copied.

  • If you have custom BundleContributors, make sure you are not only adding the CSS files but also ensuring the font folders are included in the output.

  • Finally, clear your browser cache or do a hard refresh to ensure old/broken font files are not cached.

This approach aligns with common ABP conventions, but specific official documentation for this exact scenario is not available.

  • ABP Framework does not enforce a specific naming convention for PostgreSQL schemas by default. The official documentation and community articles confirm that ABP uses PascalCase for table and column names out of the box, which aligns with .NET conventions but not with PostgreSQL's typical snake_case style.

  • The UseSnakeCaseNamingConvention() method from EF Core can be used to apply snake_case naming, but it does not fully cover inherited properties (such as those from FullAuditedAggregateRoot). This is a known limitation, and some ABP internal queries and modules may still expect PascalCase names (e.g., "AbpPermissions"), leading to migration and runtime conflicts if the physical schema uses snake_case.

  • There is currently no official ABP guidance or built-in support for enforcing snake_case across all entities, including inherited and module-provided properties. The recommended approach is to use the default PascalCase naming to ensure compatibility with ABP modules and migrations.

  • Workarounds such as custom EF Core naming conventions, query interceptors, or database views are community-driven and not officially supported. These may help in specific scenarios but can introduce maintenance overhead and compatibility risks with ABP updates.

  • As of now, there is no official roadmap or announcement regarding improved or native snake_case support for PostgreSQL in ABP Framework. The best practice is to use the default naming conventions unless you are prepared to handle the additional complexity and potential issues with custom solutions.

  • For the FullAuditedAggregateRoot property casing issue, there is no officially supported workaround. If you must use snake_case, you will need to manually configure property mappings for all inherited properties and be aware of the risks with ABP module compatibility.

  • In ABP, audit properties like LastModifierId are set based on the current user, which is determined by the ClaimsPrincipal available via ICurrentPrincipalAccessor. In background jobs (such as Hangfire), there is no authenticated user by default, so audit logging will not automatically associate changes with a user unless you explicitly set the principal.

  • Your approach of using currentPrincipalAccessor.Change(newPrincipal) is correct and aligns with official ABP guidance. However, for audit logging to work, you must ensure:

    1. The ClaimsPrincipal you create contains at least the AbpClaimTypes.UserId claim.
    2. The code that modifies the entity and calls UpdateAsync runs inside the using block of currentPrincipalAccessor.Change.
    3. Auditing is enabled for the entity type (which you have configured).
  • If you still do not see audit logs for changes made in the background job, check the following:

    • Ensure that the AbpAuditingOptions.IsEnabledForAnonymousUsers is set to true if the principal is not fully authenticated, or that your ClaimsPrincipal is constructed with the correct authentication type.
    • Make sure the background job is not running in a separate scope where auditing is disabled or overridden.
    • Confirm that the database context used for the update is the same as the one configured for auditing.
  • Example pattern (from official docs and community articles):

var newPrincipal = new ClaimsPrincipal(new ClaimsIdentity(new[] { new Claim(AbpClaimTypes.UserId, user.Id.ToString()), new Claim(AbpClaimTypes.UserName, user.UserName) }, "CustomAuthType")); // Set an authentication type

using (currentPrincipalAccessor.Change(newPrincipal)) { // All repository updates here will use the specified user for audit logging await configurationRepository.UpdateAsync(configuration); }


- If you want to ensure auditing for anonymous/background users, set:

  ```csharp
Configure<AbpAuditingOptions>(options =>
  {
      options.IsEnabledForAnonymousUsers = true;
  });

  • The error message Invalid credentials. 80090308: LdapErr: DSID-0C090450, comment: AcceptSecurityContext error, data 52e, v2580 indicates that the LDAP server is rejecting the username or password provided. This is a standard LDAP error (code 49, data 52e) meaning "invalid credentials".

  • Common causes and solutions:

    1. Double-check the username and password you are using for LDAP authentication. Ensure there are no typos and the account is not locked or expired.
    2. Make sure the LDAP settings (server address, port, base DN, etc.) are correctly configured in your ABP application.
    3. If you are using Active Directory, the username format may need to be user@domain or DOMAIN\\user.
    4. Ensure the user account has permission to bind to the LDAP server.
    5. If you are running in a container, ensure all required native libraries (like libldap) are installed and compatible with your environment.
  • After installing missing packages (like libldap), restart your application and verify the configuration again.

  • If you have enabled LDAP login for a tenant, confirm that the feature is enabled in both the host and tenant, and that the settings are correct.

  • You can also check the AbpFeatureValues table and clear the cache if changes are not reflected.

  • For more details and troubleshooting steps, refer to the official documentation and support threads below.

  • If you use HangfireBackgroundWorkerBase directly, you do not need the HangfirePeriodicBackgroundWorkerAdapter. The adapter is only necessary when you want to run ABP's IBackgroundWorker implementations (such as AsyncPeriodicBackgroundWorkerBase) on Hangfire, bridging ABP's background worker system to Hangfire's infrastructure.

  • When you implement your workers by inheriting from HangfireBackgroundWorkerBase, you are using Hangfire's native recurring job mechanism, and jobs will appear in the dashboard as you define them, without the adapter's extra entries.

  • To avoid flooding the Hangfire dashboard with HangfirePeriodicBackgroundWorkerAdapter jobs, you can disable or remove the registration of ABP's background workers that use the adapter, and instead implement your recurring jobs directly using HangfireBackgroundWorkerBase.

  • In summary: HangfirePeriodicBackgroundWorkerAdapter is not required if you use HangfireBackgroundWorkerBase. You can disable the adapter by not registering ABP background workers that rely on it.

To restrict tenant access by domain in a multi-tenant Angular app using ABP Framework, and to prevent users from switching to other tenants, you should use the domain/subdomain tenant resolver both on the backend and frontend. This ensures that each tenant is only accessible from its assigned domain, and tenant switching is disabled.

Solution Steps:

  1. Frontend (Angular) Configuration:
    • Set the baseUrl in your environment configuration to use the {0} placeholder for the tenant name:

application: { baseUrl: "https://{0}.koimpact.tw", name: "Sroi" }

   - With this setup, when the app runs on `https://imm.koimpact.tw`, the tenant name will be resolved as `imm`. The Angular app will send the `__tenant` header automatically based on the subdomain.

   - When you use the `{0}` placeholder in `baseUrl`, the tenant switching component (e.g., on the login page) will be hidden, so users cannot switch tenants from the UI.

2. **Backend Configuration:**
   - In your backend (e.g., in `YourProjectNameHttpApiHostModule`), configure the domain tenant resolver:
     ```csharp
Configure<AbpTenantResolveOptions>(options =>
     {
         options.AddDomainTenantResolver("{0}.koimpact.tw");
     });
  • This ensures that the backend only resolves the tenant from the subdomain and does not allow switching tenants via headers or query strings.
  1. Identity Server / Auth Server:

    • Make sure your IdentityServer or OpenIddict client configuration allows redirect URIs for each tenant domain (e.g., https://imm.koimpact.tw).
    • Do not use wildcards like https://*.koimpact.tw in CORS or redirect URIs; instead, explicitly list each allowed tenant domain.
  2. Preventing Tenant Switching:

    • With the above configuration, the Angular app will not show the tenant switcher, and the backend will only resolve tenants by domain. Users cannot switch tenants by manipulating headers or query strings.

Summary:

  • Use {0} in baseUrl for tenant isolation.
  • Configure backend to resolve tenants only by domain.
  • List each tenant domain explicitly in your auth server's allowed origins and redirect URIs.
  • Tenant switching is automatically disabled in the UI with this setup.

  • In ABP, the antiforgery system is enabled by default and uses a cookie (default: XSRF-TOKEN) and a request header (default: RequestVerificationToken). Your custom header X-XSRF-TOKEN and cookie name are valid, but you must ensure the client-side code (JS or Blazor) reads the cookie and sends it in the header for every POST/PUT request. If the header is sent but the cookie is missing, validation fails.
  • The error “cookie token and request token were swapped” typically means the antiforgery system received the tokens in the wrong order, or the cookie was not present at all. This can happen if the browser blocks the cookie (e.g., due to SameSite=None without Secure, or proxy misconfiguration).
  • Your configuration for Cookie.SameSite = None and Cookie.SecurePolicy = Always is correct for cross-site scenarios, but only if HTTPS is enforced end-to-end. If any hop is HTTP, the browser will not send the cookie.
  • When running behind Azure Container Apps (Envoy), ensure that:
    • UseForwardedHeaders is the very first middleware.
    • The X-Forwarded-Proto header is set to https by the ingress.
    • The application always sees requests as HTTPS (Request.IsHttps == true).
  • If the antiforgery cookie is not being set or sent, check:
    • The initial GET to the login page must return a Set-Cookie: XSRF-TOKEN=...; SameSite=None; Secure header.
    • The browser must accept and store this cookie. Use DevTools to confirm.
    • The POST request must include both the cookie and the header.
  • There is no ABP middleware that rewrites or clears the antiforgery cookie after UseForwardedHeaders. However, if the pipeline is misordered or the request is not seen as HTTPS, the cookie may not be set.
  • The Account Public login page expects the antiforgery header to match the configured name. If you changed it to X-XSRF-TOKEN, ensure all client-side code (including Blazor and any JS) uses this header.
  • No additional ABP setting is required for Envoy/ACA, but you must ensure forwarded headers and HTTPS are handled correctly.
  • For more detailed tracing, enable logging for Microsoft.AspNetCore.Antiforgery and Volo.Abp.AspNetCore.Mvc.AntiForgery at the Debug or Trace level in your logging configuration.
  • ABP does not use a different antiforgery token pattern; it uses the standard ASP.NET Core antiforgery system.
  • If Elsa Studio WASM is served from the same domain and shares cookies, it could interfere if it changes or clears cookies, but this is unlikely unless it explicitly manipulates the antiforgery cookie.

Troubleshooting Steps:

  1. Confirm the initial GET to the login page sets the XSRF-TOKEN cookie with SameSite=None; Secure.
  2. Confirm the POST request includes both the XSRF-TOKEN cookie and the X-XSRF-TOKEN header.
  3. Ensure all requests are seen as HTTPS by the app (check Request.IsHttps).
  4. If using a custom header, ensure all ABP and client code use the same header name.
  5. If the problem persists only in incognito or after a cold start, it may be a timing or caching issue—ensure the cookie is set before the POST.
  6. If using multiple containers or instances, ensure all share the same data protection keys and application name/discriminator.

Example: Logging Configuration

// appsettings.json
"Logging": {
  "LogLevel": {
    "Default": "Information",
    "Microsoft.AspNetCore.Antiforgery": "Debug",
    "Volo.Abp.AspNetCore.Mvc.AntiForgery": "Debug"
  }
}

This error ("An internal error occurred during your request!" with a NullReferenceException in ABP Suite's CRUD Page Generator) is a known issue, especially in modular or microservice solutions, and is often related to the way ABP Suite parses your solution's structure and DbContext extension files.

How to Resolve

  1. Check for Multiple *DbContextModelCreatingExtensions.cs Files

    • ABP Suite expects only one *DbContextModelCreatingExtensions.cs file per module. If you have more than one (e.g., both LeadsDbContextModelCreatingExtensions.cs and LeadsCustomDbContextModelCreatingExtensions.cs), Suite may fail with a NullReferenceException.
    • Solution: Keep only one such file per module and move all configuration methods into it.
  2. Verify File Paths in Suite Configuration

    • Ensure that your solution's .abp/suite/appsettings.json points to the correct paths for your DbContext and extension files.
    • If you have moved or renamed files, update the paths or remove and re-add your solution in Suite.
  3. Check for Missing or Misnamed Files

    • Make sure the expected files (like LeadsDbContextModelCreatingExtensions.cs) exist and are not excluded from the project.
  4. Remove and Re-Add Solution in Suite

    • Sometimes Suite caches old paths. Remove your solution from Suite and add it again to refresh its internal cache.
  5. Update to Latest Suite and ABP Version

    • Ensure both ABP Suite and your project packages are on the latest compatible versions.
  6. If You Need Custom EF Core Configurations

    • Since Suite overwrites the extension file, you can temporarily move your customizations to a separate method or file, then re-apply them after code generation.

References and More Details

These support threads contain detailed discussions and workarounds for similar issues.


If you follow these steps and ensure only one *DbContextModelCreatingExtensions.cs file exists per module, the error should be resolved. If you need to keep custom configurations, consider merging them into the single extension file or waiting for an official fix that supports custom/extended files.
