Installing Poetry in a Docker container no longer working

[radumarg]

I am using Poetry to install a python project using Poetry in a Docker container. Everything used worked fine until I switched to the latest version of Poetry (1.2.1). Now when I run my container, after starting a python shell, when I want to import any module installed by the project I get: ModuleNotFoundError: No module named xxxx.

The poetry install works fine, I attached to a running container and run it myself and found that it works without problems. I tried installing my project globally in the system environment and using a virtual env. In both cases, I get the same error: module not found when trying to import a module. I double-checked and verified that I am using the correct python executable when opening a python shell.

The docker file I used is listed here: https://stackoverflow.com/questions/73997844/installing-a-python-project-using-poetry-in-a-docker-container

What can I do to debug this issue?

Looks like #6459
