Hello World, Unable to import module 'app': No module named 'app'

Dear folks,

I read through #1345 thread. It is closed.
There is a reference to the fact that on Linux (WSL falls into the definition) , a code must be in /home/{user} and in my case it is, yet the issue persists.
Running environment:
Windows 11, WSL 1
SAM CLI, version 1.97.0
Docker desktop version 4.21.1 (114176

The code is located in /home/{user}/sam-app

command:
sam local invoke HelloWorldFunction -e events/event.json --debug

2023-09-15 13:05:01,864 | Code /home/{user}/sam-app/.aws-sam/build/HelloWorldFunction is not a zip/jar file
2023-09-15 13:05:03,864 | Local image is up-to-date

Any suggestion?
Thank you

Reproduce the reported command, `sam local invoke HelloWorldFunction -e events/event.json --debug`, in the stated WSL and Docker environment. Inspect `/home/{user}/sam-app/.aws-sam/build/HelloWorldFunction` and the debug output to determine why the `app` module is not available; done means the HelloWorld function imports and invokes successfully.
