@louisbrulenaudet you'll just have to do a few style fixes (trailing whitespaces) before being able to merge.

Hi @aymeric-roucher, normally I've made the necessary corrections and removed the whitespaces, but I'm still getting a validation error that I can't explain.

Could you tell me what you think is wrong?

[aymeric-roucher]

@louisbrulenaudet the error in both check_repository_consistency and check_code_quality is the following:

The following objects docstrings do not match their signature. Run `make fix-copies` to fix this. In some cases, this error may be raised incorrectly by the docstring checker. If you think this is the case, you can manually check the docstrings and then add the object name to `OBJECTS_TO_IGNORE` in `utils/check_docstrings.py`.
- HfApiEngine

I believe it might be because 3 of the 4 arguments are defined as (str, optional) in the docstrings but are only str instead of Optional[str] in their signature, so should be strin the docstrings (yes the verification is picky 😅). You can run make fix-copies to check this.
