pre-commit config top level exclude doesn't work? - mypy

Question

I have the following .pre-commit-config.yaml file. At the first line, I have this top level exclude path to exclude all checks in that folder, but for some reason, the mypy hook still outputs errors from files in that folder. Could someone help me understand what's going on? Thanks.
exclude: "src/project/proto/"

I also have this mypy.ini. Just in case, I missed anything here.

Answer 1

it is working, but not in the way you expect
mypy performs dynamic analysis and will follow imports. pre-commit is not passing those filenames onto mypy but they are being checked due to follow-imports
you will need to also use mypy's settings to ignore errors there
