To download the source code for the LeptonX theme for Angular, you should use the following command, as documented in the official ABP documentation:
abp get-source Volo.Abp.LeptonXTheme
abp get-source Volo.Abp.LeptonXTheme --version 4.2.2) is correct and will download the available source code for the LeptonX theme.Regarding the difference:
If you need the source code for additional packages (like "lepton-x", "lepton-x-abp-core", "lepton-x-core"), these are included as part of the LeptonXTheme source code structure. There is no separate command to download them individually.
If you encounter errors with abp add-package ... --with-source-code, it is likely because the source code for those packages is not distributed separately, but as part of the main LeptonXTheme source.
For more details, see the official documentation:
Your folder structure matches the expected layout for the LeptonXTheme Angular source code.
If you need to build or understand the structure, refer to the documentation inside the downloaded package or the official docs.

To map all exceptions of a specific type (such as BusinessException) to a particular HTTP status code (e.g., 422 Unprocessable Entity) in ABP Framework, you need to configure custom mappings in your application's startup. While the built-in Map method is for error codes, you can achieve type-based mapping by replacing the default status code finder service.
Here's how you can do it:
using System.Net;
using Volo.Abp.AspNetCore.ExceptionHandling;
using Volo.Abp.ExceptionHandling;
public class CustomHttpExceptionStatusCodeFinder : DefaultHttpExceptionStatusCodeFinder
{
public override HttpStatusCode GetStatusCode(HttpExceptionStatusCodeContext context)
{
if (context.Exception is BusinessException)
{
return (HttpStatusCode)422; // Unprocessable Entity
}
return base.GetStatusCode(context);
}
}
using Microsoft.Extensions.DependencyInjection;
using Volo.Abp.AspNetCore.ExceptionHandling;
public override void ConfigureServices(ServiceConfigurationContext context)
{
context.Services.AddTransient<IHttpExceptionStatusCodeFinder, CustomHttpExceptionStatusCodeFinder>();
}
This will ensure that all exceptions of type BusinessException are returned with HTTP status code 422.

Based on your description, the issue is likely related to localization or caching inconsistencies for the zh-hans language, especially after upgrading to ABP 9.2.2. Here are steps to diagnose and resolve the problem:
Check Localization Resource Files
Verify Language Configuration
appsettings.json and that it matches the culture names used in your localization files.Clear Distributed Cache Thoroughly
Check for Permission Caching Issues
Review Customizations
Update All Packages
Check for Known Issues
Debug Menu Generation
If the problem only occurs for zh-hans and resolves after some time, it is almost certainly a cache or localization resource issue.

ABP Suite currently does not fully handle C# nullable reference types in its code generation, which can result in nullability-related warnings when <Nullable>enable</Nullable> is set in your project. This includes navigation properties not being marked as nullable when the foreign key is nullable, and the use of FirstOrDefault() instead of First() even when the foreign key is required. These issues are known and have been reported by other users.
There is no built-in configuration or template condition in ABP Suite that allows you to automatically adjust the nullability of navigation properties or switch between First() and FirstOrDefault() based on the foreign key's nullability. Modifying the Suite's templates is possible, but there is no documented or supported way to dynamically check the foreign key's nullability within the template logic.
The recommended approach is to use ABP Suite for the initial entity generation and rapid changes, then manually fix nullability warnings in your codebase once your entities stabilize. After that, avoid using ABP Suite for further modifications to those entities to prevent reintroducing warnings.
This workflow—using Suite for initial scaffolding and then taking manual control—is the current best practice for projects that require strict nullability compliance. There is no official workaround or configuration to make ABP Suite nullability-aware as of version 9.2.1.
You may consider submitting feedback or feature requests to the ABP team for improved nullability support in future versions.

To add a resolver to the route for a replaced UsersComponent in ABP Angular, you need to override the route configuration for the Identity module. The ABP Angular modules register their own routes, so to customize them (e.g., to add a resolver), you must redefine the relevant route in your application's routing module.
Here’s how you can do it:
import { Injectable } from '@angular/core'; import { Resolve, ActivatedRouteSnapshot } from '@angular/router'; import { Observable } from 'rxjs'; import { UserService } from './user.service';
@Injectable({ providedIn: 'root' }) export class UserResolver implements Resolve
resolve(route: ActivatedRouteSnapshot): Observable<any> {
const id = route.paramMap.get('id');
return this.userService.getUserById(id);
}
}
2. **Override the Route in Your App Routing**
In your `app-routing.module.ts`, add a route for the user detail with the resolver:
```typescript
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { UserComponent } from './path-to-your-user-component';
import { UserResolver } from './path-to-your-user-resolver';
const routes: Routes = [
// ...other routes
{
path: 'identity/users/detail/:id',
component: UserComponent,
resolve: { user: UserResolver }
}
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule {}
Disable the Default Route (Optional but Recommended)
If you want to fully control the routing, you may need to prevent the default Identity module routes from being registered. You can do this by not importing the IdentityRoutingModule in your app, or by ensuring your custom route takes precedence.
Use the Resolved Data in Your Component
In your UserComponent, access the resolved data:
import { ActivatedRoute } from '@angular/router';
export class UserComponent { constructor(private route: ActivatedRoute) { this.route.data.subscribe(data => { console.log(data.user); // resolved user data }); } }
**Summary:**
You do not need to rewrite the entire `IdentityRoutingModule`. Instead, add your custom route with the resolver in your app's routing module. Angular will use your route when the path matches, and you can use the resolver as needed.

ABP Framework does not provide built-in libraries or modules specifically for consuming SOAP XML API endpoints or handling WSDL definitions. ABP is primarily focused on RESTful API development and integration.
To integrate SOAP APIs into an ABP-based application, the recommended approach is to use standard .NET libraries or third-party packages for SOAP communication, such as:
System.ServiceModel (WCF) for SOAP clients.dotnet-svcutil or Visual Studio's "Add Connected Service" to generate client proxies from WSDL.SoapCore or SoapClient.You can encapsulate the SOAP client logic in a service class within your ABP application layer or a dedicated module, and then inject and use it as needed throughout your application.
There is no official ABP documentation for SOAP integration, so you should follow standard .NET practices for SOAP API consumption.

Solution
The error message "invalid_grant", error_description: "The specified token is invalid." typically occurs during the OpenID Connect authorization code flow when the authorization code is invalid, expired, or has already been used. In ABP microservice solutions with a separated AuthServer (using OpenIddict), this is a common scenario if:

There is a confirmed performance regression in ABP 9.2.x related to tracking many-to-many navigation properties with large collections, as you described. The issue is specifically triggered when using .Include(x => x.PartnerStudents) with tracking enabled. This is likely due to recent changes in ABP's internal entity tracking and navigation property handling (notably in AbpEfCoreNavigationHelper and AbpEntityEntry).
As you observed, using .AsNoTracking() avoids the problem, but this is not always a viable workaround if you require change tracking.
The regression does not exist in 9.0.x, and replacing the affected services with 9.0 versions restores normal performance, confirming the root cause is in the ABP 9.2 changes.
Recommended Actions:
Review the official ABP 9.2 migration guide and release notes for any related breaking changes or known issues:
If you require tracking and cannot use .AsNoTracking(), consider temporarily reverting to ABP 9.0.x for affected DbContext/services until a fix is released.
Report the issue with a minimal reproducible example to the ABP GitHub repository if you have not already, to help the team prioritize a fix.
Monitor the ABP release notes and GitHub issues for updates regarding this regression.

To implement distributed locking in ABP Framework, you should use the IAbpDistributedLock interface, which is typically backed by Redis. Your usage of TryAcquireAsync is correct, but there are a few important points to ensure the lock works as expected:
Here is a recommended pattern for distributed locking in ABP:
public class MyService : ITransientDependency
{
private readonly IAbpDistributedLock _distributedLock;
public MyService(IAbpDistributedLock distributedLock)
{
_distributedLock = distributedLock;
}
public async Task<IActionResult> InsertFormAnswerJson(Guid id, [FromBody] JsonElement json)
{
var currentUserId = _currentUser.Id;
if (currentUserId == null)
{
return Unauthorized();
}
var lockKey = $"form-submission-lock:{currentUserId}:{id}";
// Set a reasonable timeout for the lock
await using var handle = await _distributedLock.TryAcquireAsync(lockKey, TimeSpan.FromSeconds(30));
if (handle == null)
{
_logger.LogInformation($"form-submission[duplicate]:{currentUserId}:{id}");
return StatusCode(429, "Duplicate submission detected. Please wait a moment before retrying.");
}
try
{
_logger.LogInformation($"form-submission:{currentUserId}:{id}");
await _resultAnswerService.SaveUserAnswerAsync(id, currentUserId.Value, json.GetRawText());
return Ok();
}
catch (Exception)
{
return StatusCode(500, "An error occurred while processing your submission.");
}
}
}
Key points:
If you still experience issues, verify your Redis server is accessible and not dropping connections, and that your ABP Redis configuration is correct.
