• 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
   });

• ABP Community: Patch for Chrome login issue (SameSite cookie problem)

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.

When using ABP Studio or ABP Suite to create or add modules in a Blazor WebApp (with modularity enabled), the following behaviors are expected based on current ABP tooling:

1. When you create a new module with modularity enabled, the backend and shared module projects are generated, but the Blazor (UI) elements (such as pages, components, or menu entries) may not be automatically created or registered in the main application's menu.
2. When adding a module via ABP Suite, the Blazor UI elements (pages/components) are generated inside the module, but the Suite does not automatically update the main application's menu or navigation to include these new pages. You need to manually add menu items for the new module/pages.

This is a known limitation and has been reported by other users. The ABP team has acknowledged that, especially in modular and layered setups, menu registration and page linking are not fully automated. You must manually update the menu (typically in the MenuContributor class of your main Blazor project) to add links to the new module's pages.

To add a menu item for a new module page, update your MenuContributor like this:

public class MyMenuContributor : IMenuContributor
{
    public Task ConfigureMenuAsync(MenuConfigurationContext context)
    {
        var administration = context.Menu.GetAdministration();
        context.Menu.AddItem(
            new ApplicationMenuItem(
                "MyModule",
                "My Module",
                "/my-module-page"
            )
        );
        return Task.CompletedTask;
    }
}

After adding the menu item, rebuild and run your application to see the new module/page in the navigation.

This approach is currently required until ABP Studio/Suite automates menu and page registration for modular Blazor WebApp projects.

To resolve the GUID serialization issue after upgrading to ABP 9.2.0 (which uses MongoDB.Driver v3.x), you need to address the change in default GUID representation. The new driver expects GUIDs to be stored with the UuidStandard subtype, but your existing data uses UuidLegacy.

Here’s how to handle this:

1. Set the Global GuidRepresentation
   At the very start of your application (before any MongoDB operations), set the default GUID representation to V3:

   MongoDB.Bson.BsonDefaults.GuidRepresentationMode = MongoDB.Bson.GuidRepresentationMode.V3;
   

2. Migrate Existing Data (if needed)

   • The error occurs because existing documents use the legacy GUID format. You have two options:
     • Migrate your existing data to use UuidStandard (recommended for long-term compatibility).
     • Or, configure your application to read legacy GUIDs, but this is not recommended for new projects.

   See the official MongoDB migration guide for details:
   https://abp.io/docs/9.2/release-info/migration-guides/MongoDB-Driver-2-to-3

3. Update Serialization Settings (if you have custom settings)
   If you have custom serialization logic, ensure you use the new GuidRepresentationMode.V3 and do not set the obsolete GuidRepresentation property.

4. Restart Your Application
   After making these changes, restart your application to ensure the new settings take effect.

• The root cause of your time conversion issue is the inconsistent configuration of AbpClockOptions between your MVC Web Application and your microservices. In your WebModule, you have set:

  Configure<AbpClockOptions>(options =>
  {
      options.Kind = DateTimeKind.Local;
  });
  

  while in your DemoServiceModule, you have:

  Configure<AbpClockOptions>(options =>
  {
      options.Kind = DateTimeKind.Utc;
  });
  

• This means your MVC UI is storing and interpreting DateTime values as "Local" (server time), but your microservices are using "UTC". In a distributed (microservices) environment, especially when running in containers (like Kubernetes), this will cause time drift and conversion errors, because each container/server may have a different local time or timezone configuration.

• ABP recommends always using DateTimeKind.Utc for all services and UIs, and handling user time zone conversion at the UI or API boundary. This ensures all times are stored and transferred in UTC, and only converted to the user's time zone for display or input.

• To fix this:

  1. Set AbpClockOptions.Kind = DateTimeKind.Utc in all your modules (Web, API, microservices).
  2. Use ABP's timezone conversion utilities (IClock.ConvertToUserTime, IClock.ConvertToUtc) to convert between UTC and user time zone when displaying or accepting input.
  3. Ensure your database columns are either UTC or use timestamp with time zone if you need to store offsets.

• For more details and best practices, see:

  • https://abp.io/community/articles/zk7fnrdq
  • https://abp.io/docs/latest/framework/infrastructure/timing

This approach will resolve the time drift and ensure consistent time handling across your distributed ABP application.
