The issue you are experiencing is a common one when using custom URI schemes (like portalsystem://) for OAuth redirect URIs in ABP with React Native/Expo, especially when moving from Expo Go (development) to a built APK (production). In Expo Go, deep linking is handled differently than in a standalone build, which can cause redirect issues.
Here are the steps to resolve the problem:
Check Redirect URI Registration in ABP/IdentityServer:
portalsystem://AndroidManifest Configuration:
scheme property in app.json (which you have set to portalsystem).AndroidManifest.xml, but for managed workflow, Expo handles this if the scheme is set.App.json/Build Configuration:
app.json looks correct with "scheme": "portalsystem".Expo AuthSession/Redirect URI:
AuthSession.makeRedirectUri({ useProxy: false }) to generate the redirect URI. This should match portalsystem://.const redirectUri = AuthSession.makeRedirectUri({ useProxy: false });
// Should output: portalsystem://
Production Build Differences:
Check for Typos and Consistency:
Testing:
adb logcat (for Android) to check if the intent is being received by your app.ABP/IdentityServer Logs:
Expo Documentation:
If you follow these steps and ensure all redirect URIs and schemes are consistent, the OAuth flow should work in your built APK as it does in Expo Go.

To ensure that the admin role does not regain permissions after running the migrator multiple times, you need to override the default ABP behavior that grants all permissions to the admin role during data seeding. By default, ABP's PermissionDataSeedContributor grants all permissions to the admin role every time seeding runs, which is why your manual removals are overwritten on each migration.
Solution:
You should replace the default PermissionDataSeedContributor with your own implementation that only grants the permissions you want. Here’s how to do it:
Create a Custom PermissionDataSeedContributor:
Replace the default contributor by using the Dependency(ReplaceServices = true) attribute and implement your own logic for seeding admin permissions.
[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(PermissionDataSeedContributor), typeof(IDataSeedContributor))]
public class MyPermissionDataSeedContributor : PermissionDataSeedContributor
{
public MyPermissionDataSeedContributor(
IPermissionDefinitionManager permissionDefinitionManager,
IPermissionDataSeeder permissionDataSeeder,
ICurrentTenant currentTenant)
: base(permissionDefinitionManager, permissionDataSeeder, currentTenant)
{
}
public override Task SeedAsync(DataSeedContext context)
{
var multiTenancySide = CurrentTenant.GetMultiTenancySide();
var permissionNames = PermissionDefinitionManager
.GetPermissions()
.Where(p => p.MultiTenancySide.HasFlag(multiTenancySide))
.Where(p => !p.Providers.Any() || p.Providers.Contains(RolePermissionValueProvider.ProviderName))
.Select(p => p.Name)
.Where(x => /* filter only the permissions you want admin to have */)
.ToArray();
return PermissionDataSeeder.SeedAsync(
RolePermissionValueProvider.ProviderName,
"admin",
permissionNames,
context?.TenantId
);
}
}
.Where(x => ...) with your logic to select only the permissions you want the admin role to have.Register Your Contributor: Make sure your custom contributor is registered and the default one is replaced. This is handled by the attributes above.
Remove Manual Permission Removal: You no longer need to manually remove permissions from the admin role in your seeder, as the admin will only be granted the permissions you specify.
Why this works:
ABP’s default seeding always grants all permissions to the admin role. By replacing the default contributor, you control exactly which permissions are seeded for admin, and your changes will persist across migrations and application restarts.

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.
