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.

When you add a new microservice and generate entities with ABP Suite, the permissions are registered in the database, but if the new permission group does not appear in the web UI for role assignment, it is usually due to one of the following reasons in a microservice solution:
Application Contracts Reference Missing:
The new microservice's Application.Contracts project must be referenced by the IdentityService (or the service responsible for permission management). This is required so that the permissions are registered and exposed to the permission management UI. If the reference is missing, the permission definitions will not be loaded into the permission management system.
Rebuild and Restart All Services:
After adding a new microservice and updating references, you must rebuild the entire solution and restart all related services (especially the IdentityService and AdministrationService). This ensures that the new permissions are discovered and loaded.
Permission Provider Registration:
Ensure that your new microservice's PermissionDefinitionProvider is properly implemented and included in the Application.Contracts project. The provider should define the permission group and permissions.
Database Migration:
Make sure you have applied the latest database migrations for the new microservice and the Administration database.
Cache Issues:
Clear the distributed cache (e.g., Redis) after making changes to permissions, as permission definitions are cached.
Checklist to resolve:
IdentityService.Application.Contracts to your new microservice's Application.Contracts.PermissionDefinitionProvider is present and correct.This approach aligns with common ABP microservice conventions for permission management.

The error occurs because Hangfire requires its storage (JobStorage) to be initialized before any Hangfire API is used. When you add Hangfire dependencies and initialization code to your DbMigrator project, but do not configure Hangfire storage (via AddHangfire), it throws this exception.
The recommended approach is: Do not add Hangfire modules or initialization code to your DbMigrator project. The DbMigrator's purpose is to run database migrations and seed data, not to execute background jobs. Hangfire should only be configured in your main web host (or background worker) projects where background jobs are actually processed.
If you need to keep Hangfire NuGet packages for dependency reasons, ensure you do NOT call AddHangfire or add the Hangfire module in your DbMigrator. Remove any [DependsOn(typeof(AbpBackgroundJobsHangfireModule))] or similar from your DbMigrator module.
If you must share code between projects, use a shared library for job definitions, but keep Hangfire configuration and module dependencies out of the DbMigrator.
This is a common and recommended separation in ABP solutions:
You do not need to uninstall Hangfire from your solution—just ensure the DbMigrator project does not depend on or initialize Hangfire.
