• Steps to reproduce the issue: unsure

Following up on the previous two problems with migration to commercial:

https://support.abp.io/QA/Questions/7345/Dependency-Injection-Exception-after-migration-from-open-source-to-commercial https://support.abp.io/QA/Questions/7398/DbMigrator-fails-silently-after-migration-to-abp-commercial

We have the exception seen above when logging in with the AuthServer Login UI (the AuthServer is standalone).

If I understand the error correctly, then IAccountExternalProviderAppService needs to be injected but is missing. This page https://docs.abp.io/api-docs/commercial/3.3/api/Volo.Abp.Account.ExternalProviders.AccountExternalProviderAppService.html says its part of theVolo.Abp.Account.Pro.Public.Application package, and it is installed.

How do I provide this Interface to the ServiceProvider? Or did I misunderstand the error?

You were right. I solved it. AbpLicenceCode in appsettings.secrets.json was not read in, because we added custom code to read in appsettings from different environments, which did not read in the secrets file since we did not need it before.

Now that the DbMigrator has the Licence Code, it does not crash anymore.

Maybe a suggestion: There should be an error message thrown, its really confusing and inconvenient if the program silently crashes.

Thank you for your help @liangshiwei

Further investigations:

• dotnet build works without issues
• The error occures in await application.InitializeAsync(); in StartAsync() in DbMigratorHostedService.cs:

public async Task StartAsync(CancellationToken cancellationToken)
    {
        Console.WriteLine("Starting DbMigrator...");
        using var application = await AbpApplicationFactory.CreateAsync<CapDbMigratorModule>(options =>
        {
            options.Services.ReplaceConfiguration(_configuration);
            options.Services.ReplaceConfiguration(BuildConfiguration());
            options.UseAutofac();
            options.Services.AddLogging(c => c.AddSerilog());
            options.AddDataMigrationEnvironment();
        });
        
        Console.WriteLine("0");
        
        await application.InitializeAsync();
        
        Console.WriteLine("1");

        await application
            .ServiceProvider
            .GetRequiredService<CapDbMigrationService>()
            .MigrateAsync();
        
        Console.WriteLine("2");

        await application.ShutdownAsync();
        
        Console.WriteLine("3");

        _hostApplicationLifetime.StopApplication();
        Console.WriteLine("DbMigrator finished.");
    }

It does not reach Console.WriteLine("1");. Now it comes to abp internals of which I have no idea. Maybe this helps?

You can try configure the appsettings.secrets.json

Thanks, but this is already implemented like you suggested. I'm not sure appsettings.secrets.json is even the problem :(

• ABP Framework version: v8.0

Following up on the last question with the migration to commercial: https://support.abp.io/QA/Questions/7345/Dependency-Injection-Exception-after-migration-from-open-source-to-commercial#answer-3a133714-a55b-6664-d7c0-1370c2b2102b

We now noticed that the DbMigrator does not work at all. When executed with dotnet run, there is no log output, no console output and nothing changes in the db.

I did confirm that it worked before, so it must be because of the changes while migrating to abp commercial.

dotnet -d run simply gives:

Telemetry is: Enabled
...\aspnet-core\src\Common\cap.DbMigrator\bin\Debug\net8.0\cap.DbMigrator.exe  wird ausgeführt.
Prozess-ID: 42116

and nothing more.

I don't even know how to debug this since there is no error message. It simply does nothing.

The only thing I could find where dotnet has the same behaviour is this: https://github.com/dotnet/sdk/issues/36819 where the error was in a false appsettings.json. During migration, I did fill the previously empty appsettings.secrets.json with the AbpLicenceCode. Maybe there is an issue with that?

Has anyone ever encountered this and can help?

I figured it out - I had to remove these two Packages from the .csproj File:

<PackageReference Include="Volo.Abp.Account.Application" Version="8.0.3" />
<PackageReference Include="Volo.Abp.Account.HttpApi" Version="8.0.3" />

Thank you.

• Steps to reproduce the issue: unsure

Hello,

we are currently migrating the abp open-source solution we created to abp commercial. I was following the official migration guide ( https://docs.abp.io/en/commercial/8.1/migrating-from-open-source?DB=EF ), which worked fine; I finished all steps.

Our solution is inspired by the "Mastering ABP Framework" book in which a solution with 2 application layers is presented, so the AuthServer is standalone.

Everything is working fine, but the AuthServer project throws the exception seen above at startup. Since we are relatively new to the abp framework, and a standalone AuthServer is not covered in the migration guide, we can not find the source of this exception.

Could you provide us with a guide to migrate a standalone AuthServer to ABP Commercial?
