In ABP v9.2.0, if your GetListAsync(includeDetails: true) call on IRepository<MyEntity, Guid> hangs or does not respond, it is likely due to how the default WithDetails behavior is implemented for your entity's repository. When includeDetails is true, ABP calls the WithDetailsAsync method, which by default may attempt to include all navigation properties. If your entity has deep or circular relationships, or a large object graph, this can cause performance issues or even infinite loops, especially after changes in recent ABP/EF Core versions.
The IReadOnlyRepository works because it does not use the WithDetails/includeDetails mechanism in the same way, avoiding the problematic eager loading.
To resolve this, you should override the WithDetails and WithDetailsAsync methods in your custom repository implementation to explicitly specify which related entities to include, rather than relying on the default behavior. This prevents EF Core from trying to load an overly complex or circular object graph.
Example:
public class MyEntityRepository : EfCoreRepository<MyDbContext, MyEntity, Guid>, IMyEntityRepository
{
public MyEntityRepository(IDbContextProvider<MyDbContext> dbContextProvider)
: base(dbContextProvider)
{
}
public override IQueryable<MyEntity> WithDetails()
{
return GetQueryable().Include(x => x.RelatedEntity1)
.Include(x => x.RelatedEntity2);
// Add further .Include/.ThenInclude as needed, but avoid circular references
}
public override async Task<IQueryable<MyEntity>> WithDetailsAsync()
{
return WithDetails();
}
}
Register your custom repository in the DI container and use it instead of the generic IRepository for this entity.
This approach is recommended in the official ABP documentation and best practices to avoid performance and loading issues with includeDetails.

To resolve the "invalid_request" and "redirect_uri is not valid for this client application" error when authenticating the ABP Hangfire Dashboard with OpenIdConnect, you must ensure that your AuthServer (OpenIddict) client configuration matches the redirect URI used by your API project.
Here are the required steps:
Determine the Redirect URI
https://<your-api-host>/signin-oidc
Configure the OpenIddict Client (in AuthServer)
OpenIddictApplications table or via data seed), ensure:
RedirectUri includes your API's /signin-oidc endpoint.PostLogoutRedirectUri (optional) matches your logout redirect.GrantTypes include authorization_code (and optionally hybrid if needed).Permissions include Endpoints.Authorization, Endpoints.Token, GrantTypes.AuthorizationCode, ResponseTypes.CodeIdToken, and all required scopes (e.g., roles, email, phone, MyProjectName).Example (if seeding via code):
await _applicationManager.CreateAsync(new OpenIddictApplicationDescriptor
{
ClientId = "MyProjectName_Hangfire",
ClientSecret = "YOUR_SECRET",
DisplayName = "Hangfire Dashboard",
PostLogoutRedirectUris = { "https://<your-api-host>/" },
RedirectUris = { "https://<your-api-host>/signin-oidc" },
Permissions =
{
Permissions.Endpoints.Authorization,
Permissions.Endpoints.Token,
Permissions.GrantTypes.AuthorizationCode,
Permissions.ResponseTypes.CodeIdToken,
Permissions.Scopes.Email,
Permissions.Scopes.Profile,
Permissions.Scopes.Roles,
"MyProjectName"
},
Requirements =
{
Requirements.Features.ProofKeyForCodeExchange
}
});
Update appsettings.json in API Project
"AuthServer": {
"Authority": "https://<your-auth-server-host>",
"ClientId": "MyProjectName_Hangfire",
"ClientSecret": "YOUR_SECRET",
"RequireHttpsMetadata": "true"
}
Clear Cache
Restart All Services
Test
/hangfire. You should be redirected to the AuthServer login, and after authentication, returned to the dashboard.If you still get the error, double-check that the redirect URI in the error message matches exactly what is registered in your OpenIddict client.

The ABP Framework does not provide a built-in integration for IBM i (Db2) databases. However, ABP is designed to be database-agnostic at its core, allowing you to use any EF Core-compatible provider. According to the official documentation, you can use any database system by integrating its libraries and APIs, as long as you implement the necessary repository interfaces if you want to use ABP's pre-built modules.
The compatibility between Aumerial.EntityFrameworkCore and Entity Framework Core depends on the version supported by the Aumerial provider. You should check the Aumerial.EntityFrameworkCore documentation or NuGet page to determine which EF Core versions are supported. ABP 9.1.1 uses EF Core 9.x by default, so you must ensure that Aumerial.EntityFrameworkCore is compatible with EF Core 9.x. If it only supports an earlier EF Core version, you may need to downgrade EF Core packages in your ABP solution to match the supported version.
If you use a compatible version of EF Core with Aumerial.EntityFrameworkCore, you can continue using ABP Framework 9.1.1. However, you must ensure that all ABP modules and your project dependencies are aligned with the EF Core version you choose. If you downgrade EF Core, you may need to adjust ABP package versions accordingly.
The recommended approach to use IBM i Db2 in ABP projects is:
Example configuration in your module:
[DependsOn(typeof(AbpEntityFrameworkCoreModule))]
public class MyProjectEntityFrameworkCoreModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
context.Services.AddAbpDbContext<MyDbContext>(options =>
{
options.AddDefaultRepositories();
});
Configure<AbpDbContextOptions>(options =>
{
options.UseNtiDb2(); // Replace with the actual method from Aumerial.EntityFrameworkCore
});
}
}
Replace UseNtiDb2 with the actual extension method provided by the Aumerial package.

To resolve issues after upgrading ABP from 7.3.2 to 9.2.0 with the new MongoDB driver (3.3.0+), you must update your code and dependencies according to the official migration guides:
Update all MongoDB-related NuGet packages to versions compatible with MongoDB.Driver 3.x. Ensure there are no old references to MongoDB.Bson or MongoDB.Driver from previous versions in your solution or bin/obj folders.
The error regarding IMongoQueryable<> and missing types is likely due to version mismatches or breaking changes in the MongoDB driver. The ABP 9.2 migration guide specifically notes the upgrade to MongoDB.Driver 3.x and provides a link to the official MongoDB migration guide for breaking changes.
Review and update your code according to the MongoDB Driver 2.x to 3.x migration guide. Some APIs and namespaces have changed or been removed. You may need to update usages of IMongoQueryable<> and related LINQ queries to match the new driver’s API.
Clean and rebuild your solution after removing all old MongoDB driver references.
For detailed steps and breaking changes, see:
These guides will help you identify and resolve all breaking changes related to the MongoDB driver upgrade.

The error Cannot read properties of undefined (reading 'replace') during Angular UI code generation in ABP Suite typically indicates a problem with the entity JSON file or a mismatch in the expected structure for the code generator.
For ABP 9.2.0 and ABP Studio/Suite 1.0.0, ensure the following for Angular UI code generation:
PurchaseOrder.json entity file must strictly follow the expected schema. Even a minor formatting or property issue can cause the schematics to fail.rootNamespace must be correctly set in your Angular environment configuration as described in the documentation.Steps to resolve:
PurchaseOrder.json for any missing or extra fields, especially in navigation properties and enums.environment.ts includes the correct rootNamespace under apis.default.tsconfig.base.json includes the correct @proxy paths..suite folder in your Angular project and let Suite regenerate it.If you continue to encounter this error with a valid entity file and environment, it may be a bug in the current version of the ABP Suite schematics. In that case, report the issue with your entity JSON and environment details to the ABP support team.

No, ABP's IBackgroundWorker is not tenant-safe by default. When you implement a background worker in a multi-tenant ABP application, the worker runs in the host context unless you explicitly change the tenant context. ABP does not automatically isolate or scope background workers per tenant.
To safely process tenant-specific logic, you must manually switch the tenant context using ICurrentTenant.Change for each tenant. Your approach is correct: enumerate all tenants, and for each active tenant, use ICurrentTenant.Change(tenant.Id) to set the context before executing tenant-specific logic. This ensures that all services resolved within the using block operate under the correct tenant.
Here is a refined example:
protected override async Task DoWorkAsync(PeriodicBackgroundWorkerContext workerContext)
{
var tenantStore = workerContext.ServiceProvider.GetRequiredService<ITenantStore>();
var tenants = await tenantStore.GetListAsync();
foreach (var tenant in tenants)
{
if (tenant.IsActive)
{
using (var scope = workerContext.ServiceProvider.CreateScope())
{
var currentTenant = scope.ServiceProvider.GetRequiredService<ICurrentTenant>();
using (currentTenant.Change(tenant.Id))
{
// Place tenant-specific logic here
}
}
}
}
}

To generate an OpenIddict access token for a mobile user after successful 2FA verification (so that the token is equivalent to what is returned from /connect/token), you should not manually create tokens using TokenManager or by directly generating JWTs. Instead, you should leverage the OpenIddict authorization flow, ideally by implementing a custom grant type that handles the 2FA verification and then issues a token using the same pipeline as /connect/token.
Implement a Custom Grant Type in OpenIddict:
Why Not Use TokenManager Directly?
How to Implement:
services.AddOpenIddict()
.AddServer(options =>
{
// ... other options ...
options.AllowCustomFlow("2fa");
options.SetTokenEndpointUris("/connect/token");
options.AddEventHandler<OpenIddictServerEvents.HandleTokenRequestContext>(builder =>
{
builder.UseInlineHandler(async context =>
{
if (context.Request.GrantType != "2fa")
return;
// Extract parameters (userId, code, provider, etc.)
// Perform 2FA verification
// If valid, create principal and sign in:
var principal = ...; // create principal with claims, scopes, etc.
context.Validate(principal);
});
});
});
POST /connect/token
Content-Type: application/x-www-form-urlencoded
grant_type=2fa&user_id=...&code=...&provider=...
This way, the token returned is fully compatible with ABP's authorization system and works with [Authorize] attributes and internal service calls.
This approach ensures your tokens are generated in a standard, secure, and ABP-compatible way after 2FA verification.

Oracle 数据库（包括 19c）本身并不支持原生的 BOOLEAN 类型，EF Core 在生成迁移脚本时会直接映射为 BOOLEAN，导致如你截图所示的错误。你当前用的 .HasConversion<int>() 方式（将 bool 转为 int 0/1）是主流且推荐的做法。
ABP 官方和 EF Core 社区都没有更“自动化”的通用方案，建议如下：
保持你现在的写法：
builder.Entity<BackgroundJobRecord>()
.Property(u => u.IsAbandoned)
.HasConversion<int>(); // bool 映射为 int (0/1)
这样迁移脚本会生成 NUMBER(1) 字段，兼容 Oracle。
如果有多个 bool 字段，可以写一个扩展方法批量处理，或在基类/通用配置中统一加上。
迁移脚本生成后，务必检查是否有 BOOLEAN 类型，手动改为 NUMBER(1) 或 tinyint。
参考官方文档说明：
结论：EF Core + Oracle 下，bool 字段只能用 .HasConversion<int>() 或手动映射为 NUMBER(1)。没有更自动的通用方案，这是 Oracle 的限制。

To successfully roll back from ABP 9 to ABP 8, you must ensure that both your application code and your database schema are fully reverted to their ABP 8 state. The error you are seeing indicates a schema mismatch: your ABP 8.2.3 code expects columns like IsDeleted, CreationTime, etc., but your database is missing them—likely because the ABP 9 migration dropped or altered these columns.
Here’s how to resolve this:
Restore the Database:
Clear All Caches:
Verify Connection Strings:
Check for Shadow Migrations:
Rebuild and Redeploy:
Troubleshooting:
If you follow these steps and ensure both code and database are in sync for ABP 8, the error should be resolved.
