This error (startIndex ('-1') must be a non-negative value. (Parameter 'startIndex')) is a known issue that can occur in ABP Suite's CRUD Page Generator, especially after upgrades or when working with certain project/module configurations. It is typically caused by Suite failing to parse or locate expected code patterns in your DbContext or related files, often due to:
Check Your DbContext for Duplicates or Irregularities

In ABP Blazor WebAssembly multi-tenant setups using subdomains, if logging into one tenant also authenticates you in all tenants (and host), the root cause is typically the authentication cookie's domain scope. By default, cookies are set for the parent domain (e.g., .local.test), making them accessible to all subdomains, which results in shared authentication across tenants.
To ensure tenant isolation, you must configure the authentication cookie to be scoped to each subdomain (tenant) rather than the parent domain. In Blazor WASM, this is handled by the OIDC provider and the backend's cookie settings.
Solution Steps:
Set Cookie Domain Per Subdomain:
t1.local.test, t2.local.test) instead of .local.test.Configure<CookieAuthenticationOptions>(IdentityConstants.ApplicationScheme, options =>
{
options.Cookie.Domain = null; // Do not set to .local.test
});
options.Cookie.Domain = null, the cookie will be scoped to the current subdomain.OIDC Redirect URIs:
appsettings.json for each client:
"RootUrl": "https://{0}.local.test:44334"
Blazor WASM RemoteServices Configuration:
Authority and BaseUrl to include the current tenant subdomain at runtime, as described in Step 5 of the referenced guide.Clear Cookies and Test:
Summary:
The issue is caused by the authentication cookie being shared across subdomains. Scoping the cookie to each subdomain resolves the problem and ensures proper tenant isolation.

The ABP CMS Kit does not provide an automatic mechanism to clean up or remove unused images that were previously uploaded and are no longer referenced in blog posts or pages. Uploaded files remain in storage even if they are not used in any content, which can lead to accumulation of unused images over time.
To handle this issue, you would need to implement a custom solution. A typical approach is:
This process requires custom development, as the CMS Kit does not include built-in support for orphaned file cleanup.

The error [Invalid Module] Backend module "document" does not exist in API definition. indicates that the ABP CLI is trying to generate proxies for a module ("document") that is not present in the API definition exposed by your backend at the specified URL.

To fix the issue with displaying inherited permissions at the user level in the UI, you need to ensure that the Angular Permission Management UI is aware of your custom permission value provider and can reflect the effective permissions (including those inherited from host-level/global roles). The default ABP Permission Management UI only displays permissions that are directly granted to the user or their tenant roles. It does not natively aggregate or display permissions granted via custom/global logic unless you extend the backend Permission Management AppService to include these in the returned permission data. You should override or extend the Permission Management AppService (e.g., PermissionAppService) to merge the effective permissions from your GlobalPermissionValueProvider into the Permission Management DTOs returned to the UI. This way, the UI can display the correct checked/disabled state for inherited/global permissions.
There is no built-in, standard ABP way to implement host-level roles that are assignable to tenant users and have their permissions inherited across tenants. The approach you have taken—using a custom PermissionValueProvider and disabling the IMultiTenant filter to check host-level roles—is the recommended extensibility point for this scenario. However, for a more maintainable and standard approach:
Sources:
This approach aligns with ABP's extensibility model for permissions, but the UI must be updated to reflect the effective permission state.

To extend the user entity and update the User Management Blazor UI page with a new column (including an autocomplete field from another entity), follow these steps:
Extend the User Entity
Use ABP's module entity extension system to add your new property (e.g., DepartmentId) to the IdentityUser entity. Map it to the database and configure it for the API/UI as needed.
Add a New Column to the User Table (Blazor UI)
Override the UserManagement component and add your new column programmatically:
using System.Threading.Tasks;
using Volo.Abp.AspNetCore.Components.Web.Extensibility.TableColumns;
using Volo.Abp.DependencyInjection;
using Volo.Abp.Identity;
using Volo.Abp.Identity.Blazor.Pages.Identity;
namespace YourNamespace.Blazor.Pages.Identity
{
[ExposeServices(typeof(UserManagement))]
[Dependency(ReplaceServices = true)]
public class CustomizedUserManagement : UserManagement
{
protected override async ValueTask SetTableColumnsAsync()
{
await base.SetTableColumnsAsync();
var departmentColumn = new TableColumn
{
Title = "Department",
Data = "DepartmentName" // This should match your DTO property
};
TableColumns.Get<UserManagement>().Add(departmentColumn);
}
}
}
Add Autocomplete Field to the Edit/Create Modal
Example (simplified):
<AbpInput TItem="string" @bind-Value="SelectedDepartmentId" Label="Department" />
<!-- Replace with your autocomplete component and logic -->
In your code-behind, load the list of departments and handle selection.
Map the Property in DTOs and API
Ensure your new property is included in the relevant DTOs and mapped in the API layer so it appears in the UI and is persisted.
Migration
Add a migration and update your database to include the new column.
References:
This approach allows you to display and edit your new property (with autocomplete) directly in the user management page.

In ABP Angular UI, multi-tenancy is enforced by sending the selected tenant's ID as the __tenant header on each request. If users can log in without selecting a tenant and receive all permissions, it usually means the tenant resolution is not working as intended.
Common causes:
Solution steps:
Configure<AbpTenantResolveOptions>(options =>
{
options.AddDomainTenantResolver("{0}.yourdomain.com");
options.AddHeaderTenantResolver();
options.AddCookieTenantResolver();
options.AddQueryStringTenantResolver();
});
If you have custom login logic, make sure it resolves the tenant before authenticating the user.
