• /api/abp/application-localization requires the cultureName querystring parameter. If it’s missing (or empty), ABP validates the DTO and returns 400 with: “The CultureName field is required.” (exactly what your AdministrationService log shows: CultureName=).
• In ABP MVC microservice solutions, PublicWeb/Web fetches localization at startup via MvcCachedApplicationConfigurationClient → AbpApplicationLocalizationClientProxy.GetAsync(...). In your environment, the request ends up as CultureName= (empty), so the UI app fails to boot.

Apply one of the following definitive fixes (the first is the recommended one):

1) Ensure the gateway forwards the culture to downstream services (recommended)

In Kubernetes / ingress / reverse-proxy setups, the request culture is typically resolved from one of these:

• Accept-Language header
• ABP culture cookie (set by the UI)
• Query string (cultureName, ui-culture, etc.)

Your log shows the UI is calling the gateway with ...?* and the downstream call becomes CultureName=. That strongly indicates the culture information is not being forwarded/preserved by the gateway/proxy layer.

Fix: configure the gateway/ingress so it does not drop the Accept-Language header and does not strip query strings. Concretely:

• Preserve Accept-Language end-to-end.
• Ensure the full query string is forwarded as-is (some proxies can be misconfigured to drop/normalize it).

After that, ABP will be able to resolve culture and will call: /api/abp/application-localization?cultureName=en... instead of CultureName=.

2) Force a default culture for the UI apps (defensive)

As a fallback, configure a default request culture for the MVC UI so it never ends up sending an empty culture to the backend.

In your PublicWeb and Web module (the module that configures localization), set a default culture (example en):

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Localization;
using System.Globalization;
using Volo.Abp.Modularity;

public override void ConfigureServices(ServiceConfigurationContext context)
{
    context.Services.Configure<RequestLocalizationOptions>(options =>
    {
        var defaultCulture = new CultureInfo("en");

        options.DefaultRequestCulture = new RequestCulture(defaultCulture);
        options.SupportedCultures ??= new List<CultureInfo>();
        options.SupportedUICultures ??= new List<CultureInfo>();

        if (!options.SupportedCultures.Any(c => c.Name == "en"))
            options.SupportedCultures.Add(defaultCulture);

        if (!options.SupportedUICultures.Any(c => c.Name == "en"))
            options.SupportedUICultures.Add(defaultCulture);
    });
}

This prevents CultureName from being empty even when upstream culture detection fails.

3) As a last resort: customize the application-localization endpoint validation (not recommended)

You can alter validation behavior, but this changes ABP’s standard API contract and is not recommended compared to fixing culture forwarding/default culture.

(Also note) the warning Could not find IdentityClientConfiguration for AbpMvcClient is a separate configuration issue (identity client config), not the cause of the CultureName validation error.

• Your Themes/LeptonX folder under AuthService is a copy of LeptonX MVC Razor view/component overrides from your old ABP 8 setup. After upgrading to ABP 10, the LeptonX MVC theme package you now reference no longer contains the same MVC component namespaces/types you were overriding (so imports like below break because the underlying type is gone/renamed/moved in newer LeptonX):

@using Volo.Abp.AspNetCore.Mvc.UI.Theme.LeptonX.Themes.LeptonX.Components.SideMenu.MobileNavbar
  @model MobileNavbarViewModel

• Do not try to “download LeptonX 5.1.1 source” via abp list-modules. abp list-modules lists ABP modules/templates, not the internal source of the commercial LeptonX MVC theme. Also, the LeptonX MVC theme source is not available through the public GitHub index I can search here, so I can’t provide a verified “download source code for 5.1.1” instruction.

• The correct fix is:

  1. Remove the outdated copied theme source (AuthService/Themes/LeptonX) or stop compiling it (exclude from project).
  2. Re-apply your login customization using ABP’s supported UI customization approach for ABP 10 + LeptonX, rather than keeping a hard-copied old theme folder that depends on internal component classes.

• To keep your custom login UI without the old copied theme folder:

  1. Create your own login page override using ABP’s MVC UI customization/overriding mechanisms (Account module UI customization) instead of copying LeptonX internal components.
  2. If you really must override theme components, you need to re-create overrides against the ABP 10 / current LeptonX MVC component names, not the ABP 8 ones. Your current overrides reference old component namespaces (...Components.SideMenu.MobileNavbar) that no longer match.

• If your goal is exactly “keep the old LeptonX look”, then the only reliable way is to upgrade your copied Razor files to match the new LeptonX MVC API surface. Practically:

  • Start from a fresh ABP 10 microservice template using LeptonX.
  • Compare your old customized login files with the new default login UI and re-apply only the customization pieces (HTML/CSS/branding), not the old component references.

• About “If I remove Themes folder, Login page UI is totally changed”:

  • That’s expected: you were overriding LeptonX UI by file shadowing. Once removed, ABP falls back to the packaged theme/views of your current ABP 10 setup.

• In ABP 10.1.1, the .DbMigrator output you shared (it stops right after “Creating initial migration…” and returns exit code 0) typically means the “create initial migration” step didn’t actually scaffold any EF Core migration, so the migrator ends without applying anything (no error is thrown, so the process exits successfully).

• Fix it by creating/applying the initial EF Core migration manually (this bypasses the Studio/CLI “create initial migration” wrapper and makes the failure visible if there is any design-time DbContext issue):

  1. Open a terminal in your *.EntityFrameworkCore project folder.

  2. Run Add Migration (use your actual DbContext name):

dotnet ef migrations add Initial --context YourProjectDbContext

3. Then update the database:

dotnet ef database update --context YourProjectDbContext

4. After the database is created and migrations exist, run the .DbMigrator project again. It should now apply migrations + seed data normally.

• If step (2) fails, EF Core will print the real root cause (most commonly: a design-time DbContext creation/mapping problem). In that case, the correct fix is to resolve the EF Core model/design-time error and then re-run the commands above. (In ABP v10.x, some module entity changes can require adding migrations after package updates—see the migration guides below.)

• Your new error is the same root problem as the previous one, just surfacing at the next ABP package:
  No provider found for InjectionToken CORE_OPTIONS (used by @abp/ng.oauth’s OAuthConfigurationHandler) means Angular is loading ABP code that tries to inject(CORE_OPTIONS) but the token instance that was provided by CoreModule.forRoot(...) is not the same token instance that @abp/ng.oauth is injecting.

In practice, this almost always happens when your workspace ends up with two physical copies / entry points of ABP Angular packages (or they’re resolved from the wrong place). Then:

• CoreModule.forRoot() provides CORE_OPTIONS (copy A)
• @abp/ng.oauth injects CORE_OPTIONS (copy B)
  => DI can’t find it → NG0201.

1) Fix package resolution (most important)

In an Nx / monorepo, check your tsconfig.base.json (and any app-level tsconfig) for any paths mapping that touches @abp/* or @volo/* or redirects modules to local sources.

Apply this in the app tsconfig that builds/runs (or tsconfig.base.json), so ABP always resolves from node_modules:

{
  "compilerOptions": {
    "paths": {
      "@abp/*": ["node_modules/@abp/*"],
      "@volo/*": ["node_modules/@volo/*"]
    }
  }
}

Then do a clean install:

rm -rf node_modules package-lock.json yarn.lock
npm install

This addresses both the original RestService issue and the current CORE_OPTIONS issue (they’re symptoms of the same duplication/resolution problem).

2) Keep CoreModule.forRoot(...) in the root module only (you already did)

Your updated AppModule import order is fine. The key rule is:

• CoreModule.forRoot({ environment, registerLocaleFn }) must be executed once (root module)
• Other modules should not call forRoot() again.

3) Angular version alignment

You mentioned “Angular 20” initially, but your package.json shows Angular 21.0.0. Running ABP 10.2.0 with Angular 21 increases the chance of hitting build/runtime incompatibilities and dependency duplication issues. The safest route is to keep Angular at the version ABP 10.x templates target, or upgrade ABP packages to a version that officially targets your Angular major.

(There isn’t a single “NgModule vs standalone” requirement here; the error is DI token duplication, not the bootstrap style.)

If you apply step (1) and clean reinstall, CORE_OPTIONS should resolve and the app should pass this startup stage.

• AutoMapper (NuGet / .NET side): Yes, you can safely override the transitive AutoMapper version without upgrading ABP or moving to .NET 9.
  1. In every project that ends up referencing AutoMapper (typically *.Application, sometimes *.HttpApi.Host depending on your module graph), add an explicit package reference to a patched AutoMapper version so NuGet resolves your version instead of the transitive one:

<ItemGroup>
       <PackageReference Include="AutoMapper" Version="15.1.1" />
       <PackageReference Include="AutoMapper.Extensions.Microsoft.DependencyInjection" Version="15.1.1" />
     </ItemGroup>

2. Rebuild and verify the resolved versions (e.g., dotnet list package --include-transitive).

Configuration-based mitigation in ABP specifically: ABP uses AutoMapper via its integration package, but I could not find (in verified ABP sources available to me) an ABP-provided setting like “limit mapping depth” that you can flip to mitigate the specific AutoMapper recursion DoS issue. The reliable mitigation here is overriding to a fixed AutoMapper version.

• Select2 (npm / React side): In ABP React apps, Select2 is not a typical built-in dependency, and I could not verify from ABP sources here where select2@4.0.13 would be coming from in an ABP React 8.2.3 solution. However, if your scanner reports it as transitive, the standard mitigation on the React/npm side (without any ABP upgrade) is to force/override the dependency version at the package manager level:
  • npm (overrides):

{
      "overrides": {
        "select2": "4.1.0-rc.0"
      }
    }

• yarn (resolutions):

{
      "resolutions": {
        "select2": "4.1.0-rc.0"
      }
    }

Then reinstall (rm -rf node_modules package-lock.json and npm install, or the equivalent for yarn/pnpm) and re-check the lockfile.

Important note about your reported Select2 advisory: your message says “versions prior to 4.0.8 are vulnerable”, but you have 4.0.13, which is not “prior to 4.0.8”. So either:

• the advisory text is mismatched, or
• the scanner is flagging Select2 for a different reason, or
• the actual installed version is not what you think (lockfile says otherwise).

The practical, framework-independent mitigation remains: ensure the lockfile resolves to a non-vulnerable version and avoid using HTML templates with untrusted remote data.

• Best practice in ABP (when you cannot upgrade the framework):
  1. Override patched transitive versions (NuGet via explicit PackageReference, npm via overrides/resolutions).
  2. Regenerate lockfiles and verify actual resolved versions in CI.
  3. Prefer DTO projections (e.g., Select(...) / query projection) over deep object graph mapping when feasible to reduce risk and cost of mapping large/deep graphs.

• Install/upgrade the ABP CLI:

dotnet tool update -g Volo.Abp.Cli
  # (or first time)
  dotnet tool install -g Volo.Abp.Cli

• In your solution folder (where the .sln is), run:

abp update

This updates all ABP-related NuGet and NPM packages in the solution.

• Rebuild and then check the official upgrading notes for version-specific/manual steps (breaking changes, migrations, etc.):

  • https://abp.io/docs/latest/release-info/upgrading

• If you only want to update NPM packages (Angular UI), you can run the update command with the --npm option (supported by the ABP CLI):

abp update --npm

• Notes:

  • abp update targets ABP packages. For non-ABP NuGet packages, use standard .NET tooling (e.g., dotnet list package --outdated and update as needed), but keep ABP packages on consistent versions.

• You do not need to migrate to standalone (bootstrapApplication) just to fix this. ABP Angular packages still work with NgModule-based apps.
• RestService is already provided in root, so NG0201: No provider found for RestService typically indicates the @abp/* packages are not being resolved/loaded correctly, or ABP’s core options/providers are not actually being registered due to build/package resolution issues.

1) Ensure ABP Core is initialized exactly once (root module only)

Keep CoreModule.forRoot(...) only in a module that is imported by AppModule (directly or through your AbpModule) and make sure it is not imported again elsewhere.

Your AbpModule approach is OK, but make sure other feature/shared modules don’t import CoreModule again (they should import CoreModule without forRoot, or not import it at all if not needed).

2) Fix common Angular 20 + ABP DI “no provider” cause: TS paths overriding @abp/*

After upgrades, a very common reason for ABP DI tokens/providers not being found is that your tsconfig*.json contains paths mappings that cause @abp/* (and/or @volo/*) to resolve to something other than node_modules (e.g., a local projects/* folder, old source copies, monorepo mappings, etc.).

Add (or override) these mappings in the tsconfig used by the Angular app that runs (often tsconfig.app.json or apps/<app>/tsconfig.json):

{
  "compilerOptions": {
    "paths": {
      "@abp/*": ["node_modules/@abp/*"],
      "@volo/*": ["node_modules/@volo/*"]
    }
  }
}

Then clean + reinstall:

rm -rf node_modules package-lock.json yarn.lock
npm install   # or yarn
npm start

This ensures Angular resolves @abp/ng.core from the installed package (where RestService is registered), not from an unintended location.

3) Keep package versions normalized (important after major Angular upgrade)

Make sure all @abp/* and @volo/* packages are on the same ABP minor/patch line (don’t mix different 10.x.y versions). Mixed versions can cause DI/provider graph mismatches at runtime.

If you apply (2) + clean install, this usually resolves “No provider found for RestService” symptoms in Angular 20 upgrades.

• In ABP v8.2.3 there is no built-in API to read the “current retry/try count” from inside your IBackgroundJob<TArgs> implementation when you use the Default Background Job Manager.
• With the default manager, ABP persists jobs and keeps a try count internally; it retries until success or until the job times out, and if timed out it marks the job as abandoned and leaves it in the database. So the reliable way to detect “retries finished” is to use the persisted job record (e.g., IsAbandoned) rather than trying to infer it inside the job.

What to do for your requirement (recommended approach)

1. Do not wait for “retry count = 10” with DefaultBackgroundJobManager, because the default mechanism is timeout-based (abandon when timed out), not “max 10 tries”.
2. Implement “max 10 attempts” yourself in the job arguments and persist failures yourself:
   • Add fields to your job args like Attempt and MaxAttempts = 10.
   • In ExecuteAsync, wrap your logic in try/catch:
     • On failure, if Attempt < MaxAttempts, enqueue the same job again with Attempt + 1 (optionally with delay).
     • If Attempt == MaxAttempts, insert a row into your custom table (FailedJobs table) and stop re-enqueuing.
   • This gives you full control and lets you expose a “Re-run” button that simply enqueues the job again using the stored args.

Example skeleton:

public class MyJobArgs
{
    public int Attempt { get; set; } = 1;
    public int MaxAttempts { get; set; } = 10;

    public Guid BusinessId { get; set; }
}

public class MyJob : IBackgroundJob<MyJobArgs>
{
    private readonly IBackgroundJobManager _backgroundJobManager;
    private readonly IFailedJobRepository _failedJobRepository; // your table/repo

    public MyJob(
        IBackgroundJobManager backgroundJobManager,
        IFailedJobRepository failedJobRepository)
    {
        _backgroundJobManager = backgroundJobManager;
        _failedJobRepository = failedJobRepository;
    }

    public async Task ExecuteAsync(MyJobArgs args)
    {
        try
        {
            // Do work...
        }
        catch (Exception ex)
        {
            if (args.Attempt >= args.MaxAttempts)
            {
                await _failedJobRepository.InsertAsync(new FailedJob(
                    args.BusinessId,
                    args.Attempt,
                    ex.ToString(),
                    args // store serialized args so UI can re-run
                ));
                return;
            }

            await _backgroundJobManager.EnqueueAsync(
                new MyJobArgs
                {
                    BusinessId = args.BusinessId,
                    Attempt = args.Attempt + 1,
                    MaxAttempts = args.MaxAttempts
                },
                delay: TimeSpan.FromMinutes(1) // choose your backoff strategy
            );

            throw; // keep ABP logging behavior for the current failure
        }
    }
}

Alternative (if you must use ABP/Hangfire retry metadata)

If you are using Hangfire integration as the background job manager, Hangfire itself tracks retry attempts, but that is Hangfire-specific (not ABP’s default job manager abstraction). In that case you’d typically implement your “moved to failed table after retries” using Hangfire filters/continuations rather than ABP’s default job storage.

• Your screenshot shows the app trying to load bootstrap.bundle.min.js.map, bootstrap.min.css.map, and dotnet.runtime*.js.map and getting 404. These .map files are source maps used only for debugging. They are not required for offline/PWA runtime. You can ignore these warnings, or disable source-map generation in your build pipeline if you don’t want the console noise.

• The real problem in the screenshot is this runtime error:

  WebAssembly.Compile is disallowed on the main thread if the buffer size is larger than 4KB ...

  This typically happens when the browser blocks synchronous WASM compilation on the main thread (often due to browser/runtime constraints). In an offline/PWA scenario, this is frequently triggered by an incorrect or incomplete service-worker cache, where some of the Blazor runtime files (dotnet.native*.wasm, dotnet.runtime*.js, dlls, etc.) are served from cache in an unexpected way/version mismatch.

Solution

1. Use ABP’s standard PWA service worker setup (and don’t customize it until it works)
   • Ensure your Blazor WASM client has:
     • wwwroot/service-worker.js
     • wwwroot/service-worker.published.js
   • Ensure your *.Blazor.Client.csproj includes:

<PropertyGroup>
     <ServiceWorkerAssetsManifest>service-worker-assets.js</ServiceWorkerAssetsManifest>
   </PropertyGroup>

   <ItemGroup>
     <ServiceWorker Include="wwwroot\service-worker.js"
                    PublishedContent="wwwroot\service-worker.published.js" />
   </ItemGroup>

2. Ensure your published service worker caches the required Blazor assets Use the standard service-worker.published.js pattern (the important part is that it caches .dll, .wasm, .js, .json, .css, etc. from service-worker-assets.js). ABP docs include the canonical version; make sure yours matches that behavior.

3. After deploying changes, force a clean service-worker update

   • In browser dev tools → Application → Service Workers:
     • Unregister the service worker
   • Clear site data (cache storage included)
   • Reload, then test offline again

4. Verify the app is actually caching the Blazor runtime

   • DevTools → Application → Cache Storage → check the offline-cache-* entries
   • Confirm you see cached entries for:
     • index.html
     • service-worker-assets.js
     • dotnet.native*.wasm
     • dotnet.runtime*.js
     • *.dll

If you do the above and offline still fails with the same WebAssembly.Compile... error, then your service-worker.published.js is almost certainly serving a stale/incorrect cached runtime asset (version mismatch). The “unregister + clear site data” step resolves that in most cases.

• This is expected behavior and usually happens due to cold start + first-time client initialization:

  1. Angular first load downloads large JS/CSS bundles (and browser cache is empty). On refresh, these files come from cache so it becomes fast.
  2. After the UI loads, ABP Angular calls /api/abp/application-configuration to get localization, permissions, settings, current user, etc.
     On the very first request after an app restart (or after caches are cleared), the backend may spend time building/reading caches (especially permission/localization related). Next requests are fast because data is served from memory/distributed cache.
  3. In hosting environments (IIS/Azure/App Service/Docker), the backend can also be sleeping/idle; the first request “wakes” it up.

• What you should do (practical checklist):

  1. Measure what is slow
     • Open browser DevTools → Network and check which request takes ~1 minute:
       • If it’s mostly .js/.css files → it’s frontend bundle size / CDN / caching.
       • If it’s /api/abp/application-configuration → it’s backend initialization/cache building.
  2. Enable production optimizations
     • Make sure you deploy in Release and follow ABP production optimization guide (compression, caching headers, etc.).
  3. Warm up the backend
     • Configure your hosting to avoid cold start (always-on / preload / keep-alive). This eliminates the “first request after idle” delay.
  4. If first-load delay is UX problem: use SSR
     • ABP Angular supports SSR configuration; SSR improves First Contentful Paint and avoids long blank/white screen while bundles load.

• If the slow request is application-configuration specifically:

  • The most common reason is permission/localization config building on first hit (then cached). Ensure your distributed cache (e.g., Redis) is correctly configured and performant if you use it.
