I am also wondering why I get this error when testing the backported version.
```
_______________________________________________________ ERROR collecting

Hint: make sure your test modules/packages have valid Python names.

2.0.0 works fine.
I ran the prepare backport script `./scripts/ci/ci_prepare_packages.sh
amazon postgres mysql`.
@turbaszek do you have an idea?
EDIT:
@potiuk do you have any idea? I recreated the whole breeze env i.e. cleaned
docker (`docker system prune --all`)
