To obtain a JWT token from an ABP-based application, you typically use the /connect/token endpoint, which is provided by IdentityServer or OpenIddict in ABP solutions. The endpoint expects a POST request with the appropriate parameters, such as grant_type, client_id, client_secret, username, password, and scope.
Example request (using Resource Owner Password Credentials flow):
POST https://<your-abp-app>/connect/token
Content-Type: application/x-www-form-urlencoded
grant_type=password
&client_id=YourClientId
&client_secret=YourClientSecret
&username=admin
&password=YourPassword
&scope=YourApiScope
Replace the placeholders with your actual values. The response will include an access_token if the credentials are valid.
If you are using a development environment, make sure your API is running and accessible at the specified URL. Also, ensure that the client is configured in your IdentityServer/OpenIddict settings.

To resolve this:
Check Redirect URI Configuration
https://your-app.azurewebsites.net/swagger/oauth2-redirect.html, this exact URI must be registered as a valid redirect URI for the Swagger client.Update Client Settings
DbMigrator's appsettings.json and/or in your database (OpenIddict/IdentityServer client table) to include the correct redirect URI.Remove Client Secret for Swagger
Restart Services
Verify with Correct URL
Example configuration for Swagger client in appsettings.json:
"Swagger": {
"ClientId": "YourApp_Swagger",
"RootUrl": "https://your-app.azurewebsites.net"
}
And in your client seeding logic:
await CreateClientAsync(
name: "YourApp_Swagger",
grantTypes: new[] { "authorization_code" },
requireClientSecret: false,
redirectUri: "https://your-app.azurewebsites.net/swagger/oauth2-redirect.html",
corsOrigins: new[] { "https://your-app.azurewebsites.net" }
);
If you still encounter issues, double-check that the redirect URI in the error message matches exactly with what is registered.

Since you are using the new ABP Global Assets bundling system for Blazor WASM, and your logs confirm that both FontAwesome and Bootstrap Icons CSS files are being bundled and minified, the most common cause for icons not displaying (showing as empty squares or boxes) is that the font files themselves are not being copied or served correctly.
In ABP's new bundling system, CSS files that reference fonts (like FontAwesome or Bootstrap Icons) use relative URLs to load font files (e.g., .woff2, .ttf). If these font files are not present in the output (wwwroot/_content/...) or not mapped correctly, the icons will not render.
To resolve this, ensure the following:
If the font files are missing, you may need to update your abp.resourcemapping.js or ensure your nuget packages are up to date and not excluded from publish.
You can also try running abp install-libs to ensure all static assets are copied.
If you have custom BundleContributors, make sure you are not only adding the CSS files but also ensuring the font folders are included in the output.
Finally, clear your browser cache or do a hard refresh to ensure old/broken font files are not cached.
This approach aligns with common ABP conventions, but specific official documentation for this exact scenario is not available.

ABP Framework does not enforce a specific naming convention for PostgreSQL schemas by default. The official documentation and community articles confirm that ABP uses PascalCase for table and column names out of the box, which aligns with .NET conventions but not with PostgreSQL's typical snake_case style.
The UseSnakeCaseNamingConvention() method from EF Core can be used to apply snake_case naming, but it does not fully cover inherited properties (such as those from FullAuditedAggregateRoot). This is a known limitation, and some ABP internal queries and modules may still expect PascalCase names (e.g., "AbpPermissions"), leading to migration and runtime conflicts if the physical schema uses snake_case.
There is currently no official ABP guidance or built-in support for enforcing snake_case across all entities, including inherited and module-provided properties. The recommended approach is to use the default PascalCase naming to ensure compatibility with ABP modules and migrations.
Workarounds such as custom EF Core naming conventions, query interceptors, or database views are community-driven and not officially supported. These may help in specific scenarios but can introduce maintenance overhead and compatibility risks with ABP updates.
As of now, there is no official roadmap or announcement regarding improved or native snake_case support for PostgreSQL in ABP Framework. The best practice is to use the default naming conventions unless you are prepared to handle the additional complexity and potential issues with custom solutions.
For the FullAuditedAggregateRoot property casing issue, there is no officially supported workaround. If you must use snake_case, you will need to manually configure property mappings for all inherited properties and be aware of the risks with ABP module compatibility.

In ABP, audit properties like LastModifierId are set based on the current user, which is determined by the ClaimsPrincipal available via ICurrentPrincipalAccessor. In background jobs (such as Hangfire), there is no authenticated user by default, so audit logging will not automatically associate changes with a user unless you explicitly set the principal.
Your approach of using currentPrincipalAccessor.Change(newPrincipal) is correct and aligns with official ABP guidance. However, for audit logging to work, you must ensure:
If you still do not see audit logs for changes made in the background job, check the following:
Example pattern (from official docs and community articles):
var newPrincipal = new ClaimsPrincipal(new ClaimsIdentity(new[] { new Claim(AbpClaimTypes.UserId, user.Id.ToString()), new Claim(AbpClaimTypes.UserName, user.UserName) }, "CustomAuthType")); // Set an authentication type
using (currentPrincipalAccessor.Change(newPrincipal)) { // All repository updates here will use the specified user for audit logging await configurationRepository.UpdateAsync(configuration); }
- If you want to ensure auditing for anonymous/background users, set:
```csharp
Configure<AbpAuditingOptions>(options =>
{
options.IsEnabledForAnonymousUsers = true;
});
For more details and verified patterns, see:
If you follow these steps and still do not see audit logs, double-check that your background job is not suppressing auditing or using a different DbContext or unit of work configuration.

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:
