I'm having a problem with a newly-generated Microservice template using Angular and EF Core (with Postgres) where after it is generated, if I try to run all services and then visit http://localhost:4200/ to view the default angular frontend, I only see a white screen with a console error that says NullInjectorError: No provider for InjectionToken CORE_OPTIONS.
I was able to consistently get this error every time I create a new project from a microservice template, whereas the angular frontend works fine if I use a multi-layer template instead. I'm not able to fix this issue.
I am running a Macbook Pro with M1 chip, on Sonoma (in case it helps).

- Steps to reproduce the issue:
 
- Create a new Microservice template solution with Angular, with all the other options as above (can use create command mentioned above)
 - Go to Solution Runner. Build and Run all. Once all solutions are running, go on http://localhost:4200/ (or right-click and select Browse for the Angular solution)
 - Note that the screen is blank, and when you open Dev Tools console, you see the error above.

Hello, this issue will be addressed in the upcoming Studio release. In the meantime, you can apply the following path configuration as a temporary workaround:
//apps/angular/tsconfig.json "compilerOptions": { ... "paths": { ... "@abp/*": ["node_modules/@abp/*"], "@volo/*": ["node_modules/@volo/*"] } ... },Thank you for your understanding and cooperation.

Hi Sumeyye,
Thank for providing the work-around.
It helped prevent that error.
I am wondering why ABP Studio is marking so many of the solutions as external, even though I am not editing or running them externally (e.g. through an IDE).
This is the state of the Solution Runner:

Also, even though the frontend was able to load,

I am getting this error when trying to login, even though all my services are running.

error:invalid_request error_description:The specified 'client_id' is invalid. error_uri:https://documentation.openiddict.com/errors/ID2052 culture:en ui-culture:enI have a suspicion that this error is because the services generated from the template assumed the default SQL Server instead of Postgresql which is what I chose in ABP Studio's dialog before creating the template. Perhaps there is a bug there?
I am also note sure if this is intended, but generating a microservice template using an older version of ABP also creates a DbMigrator project, whereas with Studio and v9.1, that wasn't the case.
