#4916 (comment)

Howdy, I cloned nav2 in a fresh ros:rolling docker image + apt upgrade and ran pre-commit. ament_mypy seems to be failing (error log is much longer but I'll spare you the details); is this expected? How come it's not caught in CI?
I can open a separate issue if it's not expected and actually a bug.

@mini-1235 do you use pre-commit locally? If yes, are you able to reproduce?
