How to fix module not found error, when ng serve is run in an app service

Hello, I made an angular test application to see if I could get it to run in an app service, to try and fix an error in a different project.
The application is the basic application you get, when creating a new angular app. I then pushed it to a GitHub repo and created an app service, which gets the project from GitHub, via the action workflow YAML file it creates (also uploaded with the post), when creating the deployment. Everything works and the deployment succeeds, but upon accessing the URL, I get an application error.

Upon further investigating, I looked into the docker logs, which I have uploaded with this post and saw, that the container tries to serve the application with ng serve. I don't quite understand why azure chooses this approach to host a web app, since the build artifacts are already present. So if this could be clarified or a link to the documentation for this could be posted, I would be very thankful.

It then fails to find the ./boostrap module, which is being found when running and building locally or in the GitHub actions workflow. I have absolutely 0 clue on how to add the module or even make it not use ng serve and simply host the build artifacts. Any help is welcome.

Main Frontend Test2.txt <- github actions workflow created by the app service, I only removed the run test step.
