To set custom breadcrumbs or use the existing breadcrumb component in your ABP Angular application (especially with Lepton X or LeptonX Lite themes), follow these steps:
Import the Lepton X Breadcrumb Component:
app.module.ts:
import { LpxSideMenuLayoutModule } from '@volosoft/ngx-lepton-x/layouts';
@NgModule({
imports: [
LpxSideMenuLayoutModule,
// ...other imports
]
})
export class AppModule {}
Use the Breadcrumb Component in Your Layout:
<div class="lpx-breadcrumb-container">
<lpx-breadcrumb></lpx-breadcrumb>
</div>
Replace the Breadcrumb Component with a Custom One:
// In your component or module setup
this.replaceableComponents.add({
component: YourCustomBreadcrumbComponent,
key: eThemeLeptonXComponents.Breadcrumb,
});
Customize Breadcrumb Data:
Reference Example:
<div class="lpx-topbar-container">
<div class="lpx-topbar">
<div class="lpx-breadcrumb-container">
<lpx-breadcrumb></lpx-breadcrumb>
</div>
<!-- other topbar content -->
</div>
</div>
You can now either use the built-in breadcrumb or fully replace it with your own component as needed.

When building and deploying an ABP-based .NET MAUI app in Release mode to a physical iOS device, crashes at the splash screen are often related to linker or AOT (Ahead-Of-Time) compilation issues, especially with third-party frameworks like ABP.
The official ABP documentation for MAUI highlights that additional steps may be required for iOS provisioning and deployment. See: https://abp.io/docs/latest/framework/ui/maui/
Key troubleshooting steps:
UseInterpreter=true and MtouchLink=None without success, try reverting to the default linker settings (SdkOnly) and only set UseInterpreter=true for problematic assemblies.If a plain Microsoft .NET MAUI template works but the ABP sample does not, the issue is likely with ABP module compatibility or linker configuration.
For iOS-specific build and deployment issues, always check the latest ABP and Microsoft MAUI documentation for any breaking changes or required configuration.

The "Authorization failed! Given policy has not granted." error for /api/account/my-profile in ABP 8 microservice applications is typically caused by missing or misconfigured permissions or claims for the authenticated user.
In ABP microservice solutions, especially after upgrading to v8.0, this issue can also be related to the configuration of dynamic claims or claim type updates in IdentityServer.
If you are using IdentityServer, ensure that you have the following configuration in your IdentityServer host module to prevent claim type mismatches:
public override void PreConfigureServices(ServiceConfigurationContext context)
{
context.Services.PreConfigure<AbpIdentityServerBuilderOptions>(options =>
{
options.UpdateAbpClaimTypes = false;
});
}
Also, if you have enabled dynamic claims, try disabling it by removing or setting the following configuration to false:
context.Services.Configure<AbpClaimsPrincipalFactoryOptions>(options =>
{
options.IsDynamicClaimsEnabled = false;
});
Make sure the user has the required permissions for the endpoint. You can check and assign the necessary permissions in the Identity Management UI or via code.
If deploying behind IIS or a reverse proxy, ensure authentication headers are forwarded correctly.

The error occurs because returning IQueryable<T> directly from an ABP application service (or any Web API) is not supported. IQueryable is an interface and cannot be serialized/deserialized over HTTP, which is why you see the "could not be instantiated and populated" exception. ABP's dynamic HTTP API client and System.Text.Json cannot handle IQueryable<T> as a return type.
To work with large datasets in Blazor (including DevExpress or other grids), you should implement server-side paging, sorting, and filtering in your application service. Instead of returning IQueryable<T>, return a paged result (such as a List<T> or a PagedResultDto<T>) from your application service.
Example:
public async Task<PagedResultDto<DataDictionaryDto>> GetListAsync(PagedAndSortedResultRequestDto input)
{
var query = _dataDictionaryRepository
.WhereIf(!input.Filter.IsNullOrWhiteSpace(), x => x.Name.Contains(input.Filter));
var totalCount = await query.CountAsync();
var items = await query
.OrderBy(input.Sorting ?? "Name")
.Skip(input.SkipCount)
.Take(input.MaxResultCount)
.ToListAsync();
return new PagedResultDto<DataDictionaryDto>(totalCount, ObjectMapper.Map<List<DataDictionary>, List<DataDictionaryDto>>(items));
}
On the Blazor client, use the grid's "load data" event to call this paged API and bind the result.
This is the recommended and supported approach in ABP for large data grids.

When you encounter an HTTP 400 error after authentication in an ABP microservice solution (Blazor Server UI) deployed on AWS, the most common causes are related to misconfiguration of redirect URIs, cookie settings, or OpenIddict client registration.
Here are the steps to resolve this issue:
Check Redirect URIs in OpenIddict Application Registration
RedirectUri and PostLogoutRedirectUri for your BlazorServer client in the OpenIddict application registration exactly match the URLs used by your Blazor Server app:
https://app.dreamlist.gr/signin-oidchttps://app.dreamlist.gr/signout-callback-oidcVerify AppSettings Configuration
appsettings.json, confirm:
"AuthServer": {
"Authority": "https://auth.dreamlist.gr",
"RequireHttpsMetadata": true,
"ClientId": "BlazorServer",
"ClientSecret": "1q2w3e*"
}
"App": {
"SelfUrl": "https://app.dreamlist.gr"
}
SelfUrl must match the actual public URL of your Blazor Server app.Check Cookie and SameSite Settings
Configure<CookiePolicyOptions>(options =>
{
options.MinimumSameSitePolicy = SameSiteMode.Lax;
});
services.ConfigureApplicationCookie(options =>
{
options.Cookie.Domain = ".dreamlist.gr";
options.Cookie.SameSite = SameSiteMode.Lax;
});
Check for Valid Redirect URI in AuthServer Logs
Check for Proxy or Load Balancer Headers
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});
ASPNETCORE_FORWARDEDHEADERS_ENABLED=true in your environment variables.Clear Browser Cookies and Test Again
Check for HTTPS Everywhere
If you follow these steps and ensure all URLs and settings are consistent, the 400 error after login should be resolved.

When using ABP Studio or ABP Suite to create or add modules in a Blazor WebApp (with modularity enabled), the following behaviors are expected based on current ABP tooling:
This is a known limitation and has been reported by other users. The ABP team has acknowledged that, especially in modular and layered setups, menu registration and page linking are not fully automated. You must manually update the menu (typically in the MenuContributor class of your main Blazor project) to add links to the new module's pages.
To add a menu item for a new module page, update your MenuContributor like this:
public class MyMenuContributor : IMenuContributor
{
public Task ConfigureMenuAsync(MenuConfigurationContext context)
{
var administration = context.Menu.GetAdministration();
context.Menu.AddItem(
new ApplicationMenuItem(
"MyModule",
"My Module",
"/my-module-page"
)
);
return Task.CompletedTask;
}
}
After adding the menu item, rebuild and run your application to see the new module/page in the navigation.
This approach is currently required until ABP Studio/Suite automates menu and page registration for modular Blazor WebApp projects.

To resolve the GUID serialization issue after upgrading to ABP 9.2.0 (which uses MongoDB.Driver v3.x), you need to address the change in default GUID representation. The new driver expects GUIDs to be stored with the UuidStandard subtype, but your existing data uses UuidLegacy.
Here’s how to handle this:
Set the Global GuidRepresentation
At the very start of your application (before any MongoDB operations), set the default GUID representation to V3:
MongoDB.Bson.BsonDefaults.GuidRepresentationMode = MongoDB.Bson.GuidRepresentationMode.V3;
Migrate Existing Data (if needed)
UuidStandard (recommended for long-term compatibility).See the official MongoDB migration guide for details:
https://abp.io/docs/9.2/release-info/migration-guides/MongoDB-Driver-2-to-3
Update Serialization Settings (if you have custom settings)
If you have custom serialization logic, ensure you use the new GuidRepresentationMode.V3 and do not set the obsolete GuidRepresentation property.
Restart Your Application
After making these changes, restart your application to ensure the new settings take effect.

The root cause of your time conversion issue is the inconsistent configuration of AbpClockOptions between your MVC Web Application and your microservices. In your WebModule, you have set:
Configure<AbpClockOptions>(options =>
{
options.Kind = DateTimeKind.Local;
});
while in your DemoServiceModule, you have:
Configure<AbpClockOptions>(options =>
{
options.Kind = DateTimeKind.Utc;
});
This means your MVC UI is storing and interpreting DateTime values as "Local" (server time), but your microservices are using "UTC". In a distributed (microservices) environment, especially when running in containers (like Kubernetes), this will cause time drift and conversion errors, because each container/server may have a different local time or timezone configuration.
ABP recommends always using DateTimeKind.Utc for all services and UIs, and handling user time zone conversion at the UI or API boundary. This ensures all times are stored and transferred in UTC, and only converted to the user's time zone for display or input.
To fix this:
AbpClockOptions.Kind = DateTimeKind.Utc in all your modules (Web, API, microservices).IClock.ConvertToUserTime, IClock.ConvertToUtc) to convert between UTC and user time zone when displaying or accepting input.timestamp with time zone if you need to store offsets.For more details and best practices, see:
This approach will resolve the time drift and ensure consistent time handling across your distributed ABP application.

The warning The localization source separator (::) not found. and the display of LongWelcomeMessage as a literal string indicate that the Angular localization key is not being resolved. This usually means the resource or key is not registered or loaded correctly in your Angular app.
In ABP Angular, localization keys must be referenced as ResourceName::Key. For example:
{{ 'MyProjectName::LongWelcomeMessage' | abpLocalization }}
You must also ensure that the resource and key are registered in your Angular module. In your app.module.ts, you should have something like:
import { provideAbpCore, withOptions } from '@abp/ng.core';
@NgModule({
providers: [
provideAbpCore(
withOptions({
localizations: [
{
culture: 'en',
resources: [
{
resourceName: 'MyProjectName',
texts: {
"LongWelcomeMessage": "Welcome to the application. This is a startup project based on the ABP framework. For more information visit"
}
}
]
}
]
}),
),
],
})
export class AppModule {}
If you only use backend localization, ensure the backend returns the correct resource and key, and that the Angular app is configured to use it.
Double-check that the resource name and key match exactly, and that you are using the correct separator (::).
If you recently upgraded, compare your app.module.ts and localization configuration with a fresh ABP template for your version, as breaking changes or template changes may have occurred.
