Cleo exceptions don't use pep8 naming conventions (and pep8-naming flake8 plugin doesn't seem to care)
Cleo's exceptions end in the suffix *Exception. PEP8 stipulates that exceptions should end in the suffix *Error. The pep8-naming flake8 extension is installed as a pre-commit hook, but is not triggering (for some reason).
see https://peps.python.org/pep-0008/#exception-names
I investigated this a bit. pep8-naming is adding this error to default ignore of flake8 config here. I think it's to be adjusted in flake8 config.
I tried activating the flake8 error, but with no luck. Might be just my lack of experience with configuring flake8. However, I don't think that *Exception is really wrong. I know it's not strictly in line with PEP8, but it's quite common to see it in projects.
