To ensure UserFriendlyException messages are shown on the Angular client:
throw new UserFriendlyException("Your custom message here");
Or, for localization:
throw new UserFriendlyException(L["YourLocalizedKey"]);
AbpExceptionLocalizationOptions if you are using localization for exception messages.Configure<AbpExceptionLocalizationOptions>(options =>
{
options.MapCodeNamespace("YourProjectNamespace", typeof(YourResource));
});
Angular Error Handling: ABP Angular UI uses a global HTTP interceptor and error handler to display user-friendly messages. If you have customized or replaced the default error handling, ensure you are not swallowing or replacing the error message.
error.error.message.Check for Microservice Gateway Issues: If you are using a gateway (like Ocelot or YARP), ensure it is not modifying or hiding the error response from the backend.
Sample: Backend:
throw new UserFriendlyException("This is a user-friendly error!");
Angular (in your service or component):
this.yourService.callApi().subscribe({
next: () => { /* success */ },
error: (err) => {
// err.error.message should contain your UserFriendlyException message
this.toastService.showError(err.error.message);
}
});
error.message).If you follow these steps and the problem persists, verify that your backend and frontend are both using compatible ABP versions and that no custom middleware or error handler is interfering with the error response.

To use LeptonX components (like <lpx-navbar>, <lpx-footer>, etc.) in a custom layout with the new ABP Studio standalone API-based configuration (app.config.ts), you must ensure that the LeptonX modules are properly registered in the providers array, since standalone configuration does not use NgModules in the traditional way.
Here's how you can resolve the issue:
Instead of importing LeptonX modules in app.config.ts as you would in app.module.ts, you need to add them to the providers array using the provide* functions exported by those modules.
For LeptonX, use the provideLpxSideMenuLayout() and provideLpxResponsive() (if needed) functions.
Example for app.config.ts:
import { ApplicationConfig } from '@angular/core';
import { provideLpxSideMenuLayout } from '@volosoft/ngx-lepton-x/layouts';
import { provideLpxResponsive } from '@volosoft/ngx-lepton-x.core'; // optional
export const appConfig: ApplicationConfig = {
providers: [
// ...other providers
provideLpxSideMenuLayout(),
provideLpxResponsive(), // only if you use lpxResponsive directive
]
};
Remove any direct module imports (like LpxSideMenuLayoutModule) from app.config.ts, as they are not compatible with standalone API-based configuration.
Ensure your custom layout component is declared as a standalone component and imports the necessary LeptonX components in its imports array.
Example:
import { Component } from '@angular/core';
import { LpxNavbarComponent, LpxFooterComponent } from '@volosoft/ngx-lepton-x/components';
@Component({
selector: 'app-custom-layout',
standalone: true,
imports: [LpxNavbarComponent, LpxFooterComponent /*, ...other LeptonX components*/],
templateUrl: './custom-layout.component.html',
})
export class CustomLayoutComponent {}
<lpx-navbar></lpx-navbar>
<!-- ... -->
<lpx-footer></lpx-footer>
By registering the LeptonX providers and importing the components in your standalone component, the LeptonX elements will render correctly in the UI.

To address the issue of handling email confirmation and user ID retrieval in your ABP Angular application:
The ABP Angular package does not provide a built-in frontend route for the "ConfirmUser" page (e.g., /Account/ConfirmUser) or a direct API endpoint like /api/account/send-email-confirmation-token out of the box. This is why you do not see a redirect or a node for this in your Angular app.
When the login error indicates that the user must confirm their email, the backend should ideally return the userId in the error response. However, as you observed, this is not always the case, especially if the backend is not customized to include it.
To resolve this:
To implement the email confirmation flow in Angular:
If you want to configure the Angular app to handle the confirmation page and API:
Example backend customization (C#):
// In your AccountController
if (!user.EmailConfirmed)
{
return Unauthorized(new
{
error_description = "You are not allowed to login! Your account is inactive or needs to confirm your email/phone number.",
userId = user.Id
});
}
Example Angular error handling:
case "You are not allowed to login! Your account is inactive or needs to confirm your email/phone number.":
const userId = err.error?.userId;
if (userId) {
this.router.navigate(['/account/confirm-user'], { queryParams: { userId } });
}
break;
If the userId is not returned, you must update your backend to include it.

To provide correct ABP.Route configuration for Angular routes with placeholders (such as :exampleId), you should define the path in your ABP.Route entries using the same placeholder syntax as in your Angular route definitions. This ensures that the menu, breadcrumbs, and icons are correctly resolved for dynamic routes.
Here's how you can adjust your configuration:
path property in your ABP.Route should match the Angular route, including placeholders. For example:{
path: `/${path}/:exampleId/${EXAMPLE_ROUTE_NAMES.a}`,
name: '::Menu:Examples:A',
parentName: '::Menu:Examples',
order: 2,
},
{
path: `/${path}/:exampleId/${EXAMPLE_ROUTE_NAMES.b}`,
name: '::Menu:Examples:B',
parentName: '::Menu:Examples',
order: 3,
},
This is correct and supported by the ABP Angular menu system.
Ensure Consistency
Make sure the path in your ABP.Route matches exactly the route definition in your Angular router, including the placeholder (e.g., :exampleId). This allows the ABP menu and breadcrumb system to resolve the correct menu item even for dynamic routes.
Parent-Child Relationships
Use the parentName property to establish the hierarchy for breadcrumbs and menu nesting.
No Need for undefined Path
Avoid using path: undefined for dynamic routes. Always specify the full path with placeholders.
Example
Here’s a minimal example for a dynamic route:
{
path: '/examples/:exampleId/subroute-a',
name: '::Menu:Examples:A',
parentName: '::Menu:Examples',
order: 2,
}
/examples/123/subroute-a, the ABP menu and breadcrumb system will correctly highlight and display the menu item for "A" under "Examples".Summary:
Define your ABP.Route path with the same placeholder syntax as your Angular route (e.g., :exampleId). This enables the ABP Angular UI to resolve menu and breadcrumb items for dynamic routes.

When you see the error "Error occurred on DB migration step! Make sure the project is compiled and working. Command output: Build started... Build failed. Use dotnet build to see the errors." in ABP Suite, it means the code generation step failed because your solution did not build successfully.
To resolve this:
dotnet build
This is a common step in the ABP Suite workflow: the Suite relies on a successful build to generate migrations and backend code. Any compilation error in your solution (including missing references, syntax errors, or misconfigurations) will cause this step to fail.

The label "Phone number confirmed" is a localization key from the ABP Identity module. The English key is defined in the Identity module's localization file:
If the Finnish (fi-FI) translation is missing, you need to add the corresponding key to your Finnish localization file (e.g., fi.json) in your project. For example:
{
"PhoneNumberConfirmed": "Puhelinnumero vahvistettu"
}

To achieve seamless single sign-on (SSO) across multiple ABP-based solutions using a shared OpenIddict auth server, you must ensure that tenants and users are synchronized across all client applications. ABP does not provide built-in automatic tenant/user provisioning out-of-the-box for this scenario, but you can implement the following approach:
Programmatic Tenant and User Creation:
ITenantAppService, IIdentityUserAppService).Example (simplified):
public class CustomOpenIddictEvents : OpenIddictServerEvents.Authentication
{
public override async Task HandleAsync(AuthenticationContext context)
{
var tenantService = context.HttpContext.RequestServices.GetRequiredService<ITenantAppService>();
var userService = context.HttpContext.RequestServices.GetRequiredService<IIdentityUserAppService>();
var tenantName = /* extract from claims or token */;
var userName = /* extract from claims or token */;
// Check and create tenant if needed
var tenant = await tenantService.FindByNameAsync(tenantName);
if (tenant == null)
{
await tenantService.CreateAsync(new TenantCreateDto { Name = tenantName });
}
// Check and create user if needed
var user = await userService.FindByUserNameAsync(userName);
if (user == null)
{
await userService.CreateAsync(new IdentityUserCreateDto { UserName = userName, ... });
}
}
}
Session Context for ICurrentUser and ICurrentTenant:
ICurrentUser and ICurrentTenant based on the claims in the access token and the tenant resolution strategy (domain, header, etc.).tenantid and user claims, and your tenant/user exists in the database, ABP will resolve the context automatically.Alternative Approach: Centralized User/Tenant Store:
Best Practice:
No official ABP documentation provides a ready-made solution for automatic cross-solution tenant/user provisioning, but the above approach aligns with ABP's extensibility model and common practices.
This approach aligns with common ABP conventions, but specific official documentation for this exact scenario is not available.

To integrate ABP Framework with Kafka as a distributed event bus provider, you can follow the official documentation which provides step-by-step guidance on configuration and usage. The documentation covers how to set up Kafka with ABP's distributed event bus system.
For Flink integration, there is no official ABP documentation or demo available specifically for Apache Flink. You would need to implement custom integration if you require Flink to process events from Kafka streams produced by ABP.
No verified source available for direct ABP-Flink integration.
