1. After updating flake8-rst-docstrings to 0.0.12 i have the  violation RST214 about docstring in ./classes/typeclass.py .
I cant imagine how i can fix this docstring :( It seems to me that replacing the first letter with a capital letter is not quite the right solution?

2. I still have pip check error of importlib-metadata like python-poetry/poetry#2042 , but i can`t find any dependencies of it in poetry.toml or poetry.lock.
