If you use HangfireBackgroundWorkerBase directly, you do not need the HangfirePeriodicBackgroundWorkerAdapter. The adapter is only necessary when you want to run ABP's IBackgroundWorker implementations (such as AsyncPeriodicBackgroundWorkerBase) on Hangfire, bridging ABP's background worker system to Hangfire's infrastructure.
When you implement your workers by inheriting from HangfireBackgroundWorkerBase, you are using Hangfire's native recurring job mechanism, and jobs will appear in the dashboard as you define them, without the adapter's extra entries.
To avoid flooding the Hangfire dashboard with HangfirePeriodicBackgroundWorkerAdapter jobs, you can disable or remove the registration of ABP's background workers that use the adapter, and instead implement your recurring jobs directly using HangfireBackgroundWorkerBase.
In summary: HangfirePeriodicBackgroundWorkerAdapter is not required if you use HangfireBackgroundWorkerBase. You can disable the adapter by not registering ABP background workers that rely on it.

To restrict tenant access by domain in a multi-tenant Angular app using ABP Framework, and to prevent users from switching to other tenants, you should use the domain/subdomain tenant resolver both on the backend and frontend. This ensures that each tenant is only accessible from its assigned domain, and tenant switching is disabled.
Solution Steps:
baseUrl in your environment configuration to use the {0} placeholder for the tenant name:
application: { baseUrl: "https://{0}.koimpact.tw", name: "Sroi" }
- With this setup, when the app runs on `https://imm.koimpact.tw`, the tenant name will be resolved as `imm`. The Angular app will send the `__tenant` header automatically based on the subdomain.
- When you use the `{0}` placeholder in `baseUrl`, the tenant switching component (e.g., on the login page) will be hidden, so users cannot switch tenants from the UI.
2. **Backend Configuration:**
- In your backend (e.g., in `YourProjectNameHttpApiHostModule`), configure the domain tenant resolver:
```csharp
Configure<AbpTenantResolveOptions>(options =>
{
options.AddDomainTenantResolver("{0}.koimpact.tw");
});
Identity Server / Auth Server:
https://imm.koimpact.tw).https://*.koimpact.tw in CORS or redirect URIs; instead, explicitly list each allowed tenant domain.Preventing Tenant Switching:

This error ("An internal error occurred during your request!" with a NullReferenceException in ABP Suite's CRUD Page Generator) is a known issue, especially in modular or microservice solutions, and is often related to the way ABP Suite parses your solution's structure and DbContext extension files.
Check for Multiple *DbContextModelCreatingExtensions.cs Files
*DbContextModelCreatingExtensions.cs file per module. If you have more than one (e.g., both LeadsDbContextModelCreatingExtensions.cs and LeadsCustomDbContextModelCreatingExtensions.cs), Suite may fail with a NullReferenceException.Verify File Paths in Suite Configuration

If You Need Custom EF Core Configurations
These support threads contain detailed discussions and workarounds for similar issues.
If you follow these steps and ensure only one *DbContextModelCreatingExtensions.cs file exists per module, the error should be resolved. If you need to keep custom configurations, consider merging them into the single extension file or waiting for an official fix that supports custom/extended files.

The error you are encountering is because the ExcelService and UserSessionsComponent are not exported in the public API of the @volo/abp.ng.identity package. This means you cannot import them directly in your custom component, as shown by the module not found errors in your screenshots.
To resolve this, these services and components must be explicitly exported in the package's index.ts files (as you illustrated in your last screenshot). Until the maintainers add these exports and publish a new version, you will not be able to use them directly from the package.
As a workaround, you can:
For long-term maintainability, it is best to request the ABP team to export these in the next release, as you have done.

To implement a fully customized login flow such as OTP-based (passwordless) login in ABP Framework, you need to override the default Account module's login logic and UI. Below are the steps and references for both ABP 4.x and 8.x versions. The Lepton theme's account flow source code is not distributed directly, but you can override and customize the login page and logic as shown below.
Override the Login Page and Model:
CustomLoginModel inheriting from LoginModel.Login.cshtml under Pages/Account to override the default UI.Example:
public class CustomLoginModel : LoginModel
{
public CustomLoginModel(
IAuthenticationSchemeProvider schemeProvider,
IOptions<AbpAccountOptions> accountOptions)
: base(schemeProvider, accountOptions)
{
}
// Override methods to implement OTP logic here
}
@page
@model YourNamespace.Pages.Account.CustomLoginModel
<!-- Custom OTP UI here -->
Implement OTP Logic:
CustomLoginModel, implement the logic to send and verify OTP.Customize the UI:

ABP Framework provides flexible support for implementing the CQRS (Command Query Responsibility Segregation) pattern, but it does not enforce it by default. ABP's architecture, especially its application service layer, naturally aligns with CQRS principles by encouraging the separation of commands (write operations) and queries (read operations).
Example: Using MediatR in an ABP module
[DependsOn(typeof(AbpAspNetCoreMvcModule))]
public class MyModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
context.Services.AddMediatR(typeof(MyModule).Assembly);
}
}
You can then define your command and query handlers as usual with MediatR.

To achieve your desired infrastructure—where only the ETL server runs Hangfire and background jobs, and the API servers do not—you need to:
In your API servers' appsettings.json or environment-specific settings, add:
"AbpBackgroundJobs": {
"IsJobExecutionEnabled": false
}
Or, in your module configuration:
Configure<AbpBackgroundJobOptions>(options =>
{
options.IsJobExecutionEnabled = false;
});
Do NOT add or configure Hangfire server on the API servers:
context.Services.AddHangfireServer() on API servers.app.UseAbpHangfireDashboard() on API servers.On the ETL server, enable Hangfire and background job execution:
Configure<AbpBackgroundJobOptions>(options =>
{
options.IsJobExecutionEnabled = true;
});
context.Services.AddHangfire(config =>
{
config.UseSqlServerStorage(Configuration.GetConnectionString("Default"));
});
context.Services.AddHangfireServer();
And in your OnApplicationInitialization:
app.UseAbpHangfireDashboard("/hangfire");
Use environment variables or separate appsettings.{Environment}.json files to control which servers enable Hangfire/background jobs.
Example:
IsJobExecutionEnabled = false, no Hangfire server.IsJobExecutionEnabled = true, Hangfire server enabled.This response was generated by AI. If it didn’t solve your problem, feel free to post a new answer — our support team will jump in to help you soon.
To remove the "host" folder from your Azure Blob Storage path when using ABP's Blob Storing system, you are correct to set IsMultiTenant = false in your container configuration. This should prevent the framework from prefixing blobs with the tenant or "host" folder. However, if you are still seeing the "host" folder, ensure the following:
Clear Existing Blobs: The "host" folder may persist from previous uploads. Try uploading a new file after applying the configuration change.
Correct Container Configuration: Double-check that the configuration is applied to the correct container and that there are no overrides elsewhere in your codebase.
No Custom Path Logic: Ensure you are not programmatically adding the "host" prefix when saving blobs.
Here is the correct configuration:
var configuration = context.Services.GetConfiguration();
Configure<AbpBlobStoringOptions>(options =>
{
options.Containers.Configure<CategoryBlobContainer>(container =>
{
container.IsMultiTenant = false; // This disables the "host" or tenant folder
container.UseAzure(azure =>
{
azure.ConnectionString = configuration["BlobStoring:Containers:AzureContainer:Configuration:ConnectionString"];
azure.ContainerName = configuration["BlobStoring:Containers:AzureContainer:Configuration:ContainerName"];
azure.CreateContainerIfNotExists = true;
});
});
});
Restart Application: After making changes, restart your application to ensure the new configuration is loaded.
Blob Path on Save: When saving blobs, use only the file name or your desired path, not a path prefixed with "host".
Example:
await _blobContainer.SaveAsync("my-image.jpg", fileStream);
If you follow these steps and still see the "host" folder, ensure that:
For more details, see the official documentation:
If the issue persists after these checks, please verify that your application is not running in a multi-tenant context elsewhere, and that the container configuration is not being overridden in another module.
