  • This issue is likely related to missing or misconfigured localization resources for the zh-hans language, which can cause permission checks or menu rendering to fail in ABP's navigation system. When a required localization key or permission display name is missing for a specific language, ABP may not render the related menu items, or permission checks may not work as expected.

  • To resolve this:

    1. Ensure that all required localization files (e.g., zh-Hans.json) exist for every module and contain all necessary keys, especially for permissions and menu items.
    2. Check that the language code in your configuration matches the file names and the culture property inside the JSON files.
    3. If you are using the Language Management module, verify that the zh-hans language is enabled and properly configured.
    4. Clear the application cache (including distributed cache like Redis) after updating localization files.
    5. Restart the application after making changes.
  • If the problem persists, check for any custom permission providers or menu contributors that may have language-specific logic or missing translations.

To achieve subdomain-based tenant resolution in a tiered ABP Blazor Server environment with a static AuthServer domain (no wildcard), you need to ensure that the tenant context is consistently and securely passed from the Blazor app (which uses subdomains) to the AuthServer (which does not use subdomains). Your approach is mostly correct, but there are some ABP-recommended practices and built-in features that can simplify and standardize this process.

Solution

1. Blazor App: Subdomain Tenant Resolution

  • Use the built-in domain/subdomain tenant resolver:
    Configure<AbpTenantResolveOptions>(options =>
    {
        options.AddDomainTenantResolver("{0}.uat.domain.io");
    });
    
  • This will resolve the tenant from the subdomain (e.g., tenant1.uat.domain.io → tenant1).

2. AuthServer: Tenant Resolution via Query String

Since your AuthServer is at a static domain (auth.uat.domain.io), you cannot resolve the tenant from the subdomain. The recommended approach is to pass the tenant name as a query string parameter (e.g., ?tenant=tenant1) when redirecting to the AuthServer.

  • In your Blazor app, when redirecting to the AuthServer for login, append the tenant name to the return URL:

    var tenantName = currentTenant.Name;
    var returnUrl = $"/signin-oidc?tenant={tenantName}";
    // Use this returnUrl in your OIDC configuration
    
  • On the AuthServer, use the built-in QueryStringTenantResolveContributor:

    Configure<AbpTenantResolveOptions>(options =>
    {
        options.TenantResolvers.Clear();
        options.TenantResolvers.Add(new QueryStringTenantResolveContributor());
        options.TenantResolvers.Add(new CookieTenantResolveContributor());
        options.TenantResolvers.Add(new HeaderTenantResolveContributor());
    });
    

    This will resolve the tenant from the tenant query string parameter.

3. Ensure Consistent Tenant Context

  • Always include the tenant name in the authentication flow (as a query string) when redirecting between the Blazor app and the AuthServer.
  • If you use ABP's built-in OIDC integration, you can override the authority and redirect URIs to include the tenant parameter.

4. CORS and Redirect URIs

  • In your IdentityServer/DbMigrator configuration, set the client RootUrl and allowed CORS origins to use the {0} placeholder:
    "RootUrl": "https://{0}.uat.domain.io"
    
  • This allows any tenant subdomain to be accepted.

5. Example: ABP Sample

ABP provides a sample for subdomain tenant resolution:

  • https://github.com/abpframework/abp-samples/tree/master/DomainTenantResolver

6. Important Notes

  • Do not clear and re-order the default tenant resolvers unless you have a specific reason. Use ABP's built-in contributors where possible.
  • The tenant context must be explicitly passed from the UI to the AuthServer if the AuthServer does not use subdomains.
  • If you want to support both host and tenant logins, ensure your logic falls back to host if no tenant is resolved.

This approach is standard for ABP multi-tenancy in tiered environments with a static AuthServer domain.

The error "The SSL connection could not be established" when logging in to ABP Studio or using the ABP CLI is typically caused by an issue with the SSL/TLS certificate validation on your machine, even though the URL is accessible in your browser.

Here are the steps to resolve this issue:

  1. Check System Date and Time

    • Ensure your system clock is correct. An incorrect date/time can cause SSL validation failures.
  2. Update Root Certificates

    • Make sure your Windows root certificates are up to date. You can do this by running Windows Update or manually updating the root certificates.
  3. Check for Network Interception

    • If you are behind a corporate proxy, firewall, or using antivirus software that intercepts SSL traffic, it may present its own certificate, which is not trusted by .NET. Try disabling such software or adding exceptions.
  4. Test with .NET

    • Open PowerShell and run:
      [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
      Invoke-WebRequest https://account.abp.io/.well-known/openid-configuration
      
    • If this fails, your .NET runtime cannot validate the SSL certificate.
  5. Update .NET SDK

    • Make sure you are using the latest .NET SDK and runtime, as older versions may not support modern TLS standards.
  6. Trusted Root CA

    • Open the certificate for https://account.abp.io in your browser, export it, and import it into your Windows "Trusted Root Certification Authorities" store.
  7. Reboot and Retry

    • After making changes, reboot your machine and try logging in again.

For more information, see the official ABP Studio installation guide:

  • https://abp.io/docs/latest/studio/installation

If the problem persists after these steps, please provide details about your network environment (proxy, VPN, etc.) and .NET version.

  • The issue you are experiencing with POST/PUT requests returning 400 Bad Request in Cypress, while working fine in the browser, is commonly related to anti-forgery (CSRF/XSRF) token validation or cookie handling in ABP applications.

Solution Steps

  1. Antiforgery Token Issue
    ABP uses antiforgery tokens for POST/PUT/DELETE requests. When using Cypress, the required antiforgery token may not be sent or may not match, especially across subdomains.

    • Ensure Cypress is sending the XSRF-TOKEN cookie and the corresponding request header (RequestVerificationToken or X-XSRF-TOKEN) with your POST/PUT requests.

    • If your frontend and backend are on different subdomains, set the antiforgery cookie's domain to the parent domain in your backend configuration:

      Configure<AbpAntiForgeryOptions>(options =>
      {
          options.TokenCookie.Domain = ".yourdomain.com"; // Use your actual parent domain
      });
      
  2. Cookie Secure Policy
    If you are running tests over HTTP (not HTTPS), you must allow the antiforgery cookie to be sent over HTTP:

    Configure<AbpAntiForgeryOptions>(options =>
    {
        options.TokenCookie.SecurePolicy = CookieSecurePolicy.None;
    });
    
  3. Cypress Configuration

    • Make sure Cypress is configured to preserve cookies between requests and is not blocking or clearing them.
    • You may need to manually extract the antiforgery token from the cookies and set it as a header in your Cypress POST/PUT requests.
  4. WebDAV and IIS
    If you are hosting on IIS, ensure the WebDAV module is disabled, as it can block non-GET requests:

    • Remove the WebDAV module from your IIS configuration.
  5. SameSite Cookie Policy
    Modern browsers and test runners may enforce SameSite cookie policies. If your app is running on different subdomains, set the antiforgery cookie's SameSite policy to Lax or None as appropriate:

    Configure<AbpAntiForgeryOptions>(options =>
    {
        options.TokenCookie.SameSite = SameSiteMode.Lax; // or SameSiteMode.None if using HTTPS
    });
    

References (validated)


Summary:
The most likely cause is antiforgery token or cookie configuration issues between Cypress and your ABP backend, especially with subdomains. Adjust your AbpAntiForgeryOptions as shown above, ensure cookies and headers are handled correctly in Cypress, and check for IIS/WebDAV interference if applicable.

To set up responsive design in an ABP Angular module, you should use standard Angular and CSS techniques, as ABP Angular projects are built on top of Angular and fully support Angular's ecosystem. ABP does not impose restrictions on how you implement responsiveness.

Here’s how you can achieve responsive design in your ABP Angular module:

  1. Use Angular’s Built-in Features:

    • Utilize Angular’s layout features, such as Angular Flex Layout or CSS Grid/Flexbox, to create responsive layouts.
    • You can install Angular Flex Layout with:
      npm install @angular/flex-layout @angular/cdk
      
    • Import FlexLayoutModule in your module and use its directives in your templates.
  2. Leverage CSS Media Queries:

    • Add your responsive CSS rules in the global styles.scss or component-specific styles.
    • Example:
      @media (max-width: 600px) {
        .my-class {
          font-size: 14px;
        }
      }
      
  3. Use Responsive UI Libraries:

    • You can integrate UI libraries like Angular Material, PrimeNG, or Bootstrap, which provide responsive components out of the box.
    • For example, to use Angular Material:
      ng add @angular/material
      
    • Then use Material’s responsive components in your templates.
  4. Customize ABP Angular Components:

    • You can override or extend ABP Angular components to add responsive behavior as needed.
    • Place your custom styles or layout logic in your module’s components.
  5. Mobile-Friendly Meta Tag:

    • Ensure your index.html includes the viewport meta tag:
      <meta name="viewport" content="width=device-width, initial-scale=1">
      

ABP Angular modules are standard Angular modules, so all Angular and web best practices for responsiveness apply.

To set custom breadcrumbs or use the existing breadcrumb component in your ABP Angular application (especially with Lepton X or LeptonX Lite themes), follow these steps:

  1. Import the Lepton X Breadcrumb Component:

    • Ensure you have imported the necessary Lepton X modules in your app.module.ts:
      import { LpxSideMenuLayoutModule } from '@volosoft/ngx-lepton-x/layouts';
      @NgModule({
        imports: [
          LpxSideMenuLayoutModule,
          // ...other imports
        ]
      })
      export class AppModule {}
      
  2. Use the Breadcrumb Component in Your Layout:

    • In your custom layout component's template, add the Lepton X breadcrumb component:
      <div class="lpx-breadcrumb-container">
        <lpx-breadcrumb></lpx-breadcrumb>
      </div>
      
    • This will render the default breadcrumb navigation as provided by the theme.
  3. Replace the Breadcrumb Component with a Custom One:

    • If you want to use your own custom breadcrumb component, you can replace the default one using the ABP replaceable components system:
      // In your component or module setup
      this.replaceableComponents.add({
        component: YourCustomBreadcrumbComponent,
        key: eThemeLeptonXComponents.Breadcrumb,
      });
      
    • This will instruct ABP to use your custom component wherever the breadcrumb is rendered.
  4. Customize Breadcrumb Data:

    • The breadcrumb component uses the Angular router configuration and ABP menu system to generate breadcrumbs. To customize the breadcrumb items, you can adjust your route definitions or menu providers accordingly.
  5. Reference Example:

    • For a full custom layout using Lepton X components (including breadcrumbs), see the following code structure:
      <div class="lpx-topbar-container">
        <div class="lpx-topbar">
          <div class="lpx-breadcrumb-container">
            <lpx-breadcrumb></lpx-breadcrumb>
          </div>
          <!-- other topbar content -->
        </div>
      </div>
      

You can now either use the built-in breadcrumb or fully replace it with your own component as needed.

  • When building and deploying an ABP-based .NET MAUI app in Release mode to a physical iOS device, crashes at the splash screen are often related to linker or AOT (Ahead-Of-Time) compilation issues, especially with third-party frameworks like ABP.

  • The official ABP documentation for MAUI highlights that additional steps may be required for iOS provisioning and deployment. See: https://abp.io/docs/latest/framework/ui/maui/

  • Key troubleshooting steps:

    1. Ensure all iOS provisioning profiles and certificates are correctly set up. See the Microsoft guide linked in the ABP docs.
    2. If you have set UseInterpreter=true and MtouchLink=None without success, try reverting to the default linker settings (SdkOnly) and only set UseInterpreter=true for problematic assemblies.
    3. Make sure all referenced libraries (including ABP modules) are compatible with .NET MAUI 9.x and iOS 17+.
    4. Clean and rebuild the solution, and delete the bin/obj folders.
    5. If the issue persists, try running the app with a minimal ABP module set to isolate the problematic dependency.
  • If a plain Microsoft .NET MAUI template works but the ABP sample does not, the issue is likely with ABP module compatibility or linker configuration.

  • For iOS-specific build and deployment issues, always check the latest ABP and Microsoft MAUI documentation for any breaking changes or required configuration.

  • The "Authorization failed! Given policy has not granted." error for /api/account/my-profile in ABP 8 microservice applications is typically caused by missing or misconfigured permissions or claims for the authenticated user.

  • In ABP microservice solutions, especially after upgrading to v8.0, this issue can also be related to the configuration of dynamic claims or claim type updates in IdentityServer.

  • If you are using IdentityServer, ensure that you have the following configuration in your IdentityServer host module to prevent claim type mismatches:

    public override void PreConfigureServices(ServiceConfigurationContext context)
    {
        context.Services.PreConfigure<AbpIdentityServerBuilderOptions>(options =>
        {
            options.UpdateAbpClaimTypes = false;
        });
    }
    
  • Also, if you have enabled dynamic claims, try disabling it by removing or setting the following configuration to false:

    context.Services.Configure<AbpClaimsPrincipalFactoryOptions>(options =>
    {
        options.IsDynamicClaimsEnabled = false;
    });
    
  • Make sure the user has the required permissions for the endpoint. You can check and assign the necessary permissions in the Identity Management UI or via code.

  • If deploying behind IIS or a reverse proxy, ensure authentication headers are forwarded correctly.

  • For more details and troubleshooting steps, see the following validated resources:

The error occurs because returning IQueryable<T> directly from an ABP application service (or any Web API) is not supported. IQueryable is an interface and cannot be serialized/deserialized over HTTP, which is why you see the "could not be instantiated and populated" exception. ABP's dynamic HTTP API client and System.Text.Json cannot handle IQueryable<T> as a return type.

To work with large datasets in Blazor (including DevExpress or other grids), you should implement server-side paging, sorting, and filtering in your application service. Instead of returning IQueryable<T>, return a paged result (such as a List<T> or a PagedResultDto<T>) from your application service.

Example:

public async Task<PagedResultDto<DataDictionaryDto>> GetListAsync(PagedAndSortedResultRequestDto input)
{
    var query = _dataDictionaryRepository
        .WhereIf(!input.Filter.IsNullOrWhiteSpace(), x => x.Name.Contains(input.Filter));
    var totalCount = await query.CountAsync();
    var items = await query
        .OrderBy(input.Sorting ?? "Name")
        .Skip(input.SkipCount)
        .Take(input.MaxResultCount)
        .ToListAsync();

    return new PagedResultDto<DataDictionaryDto>(totalCount, ObjectMapper.Map<List<DataDictionary>, List<DataDictionaryDto>>(items));
}

On the Blazor client, use the grid's "load data" event to call this paged API and bind the result.

This is the recommended and supported approach in ABP for large data grids.

When you encounter an HTTP 400 error after authentication in an ABP microservice solution (Blazor Server UI) deployed on AWS, the most common causes are related to misconfiguration of redirect URIs, cookie settings, or OpenIddict client registration.

Here are the steps to resolve this issue:

  1. Check Redirect URIs in OpenIddict Application Registration

    • Ensure that the RedirectUri and PostLogoutRedirectUri for your BlazorServer client in the OpenIddict application registration exactly match the URLs used by your Blazor Server app:
      • https://app.dreamlist.gr/signin-oidc
      • https://app.dreamlist.gr/signout-callback-oidc
    • These must be set both in your OpenIddict data seed and in the AuthServer's database.
  2. Verify AppSettings Configuration

    • In your Blazor Server app's appsettings.json, confirm:
      "AuthServer": {
        "Authority": "https://auth.dreamlist.gr",
        "RequireHttpsMetadata": true,
        "ClientId": "BlazorServer",
        "ClientSecret": "1q2w3e*"
      }
      "App": {
        "SelfUrl": "https://app.dreamlist.gr"
      }
      
    • The SelfUrl must match the actual public URL of your Blazor Server app.
  3. Check Cookie and SameSite Settings

    • In cloud environments, especially with multiple subdomains, you must ensure cookies are set with the correct domain and SameSite policy. In your Blazor Server app, configure cookies as follows:
      Configure<CookiePolicyOptions>(options =>
      {
          options.MinimumSameSitePolicy = SameSiteMode.Lax;
      });
      
    • If you are using multiple subdomains, set the cookie domain explicitly:
      services.ConfigureApplicationCookie(options =>
      {
          options.Cookie.Domain = ".dreamlist.gr";
          options.Cookie.SameSite = SameSiteMode.Lax;
      });
      
  4. Check for Valid Redirect URI in AuthServer Logs

    • A 400 error after login often means the redirect URI sent by the client does not match any registered URI in the AuthServer. Check the AuthServer logs for errors related to invalid or unregistered redirect URIs.
  5. Check for Proxy or Load Balancer Headers

    • If you are behind a load balancer or reverse proxy (common in AWS), ensure forwarded headers are configured so the app knows the correct external URL:
      app.UseForwardedHeaders(new ForwardedHeadersOptions
      {
          ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
      });
      
    • Also, set ASPNETCORE_FORWARDEDHEADERS_ENABLED=true in your environment variables.
  6. Clear Browser Cookies and Test Again

    • Old or invalid cookies can cause 400 errors. Clear cookies for your domain and try again.
  7. Check for HTTPS Everywhere

    • All URLs (app, auth, gateway) must use HTTPS. Mixed content or HTTP redirects can cause authentication failures.

If you follow these steps and ensure all URLs and settings are consistent, the 400 error after login should be resolved.
