[Bug]: pre-commit mypy does not catch errors

[neubig]

Is there an existing issue for the same bug?

• I have checked the existing issues.

Describe the bug and reproduction steps

Our pre-commit config includes mypy:

OpenHands/dev_config/python/.pre-commit-config.yaml

Lines 35 to 43 in ff3880c

	- repo: https://github.com/pre-commit/mirrors-mypy
	rev: v1.9.0
	hooks:
	- id: mypy
	additional_dependencies:
	[types-requests, types-setuptools, types-pyyaml, types-toml]
	entry: mypy --config-file dev_config/python/mypy.ini openhands/
	always_run: true
	pass_filenames: false

And it seems to be passing.

However, when running the same command with mypy directly results in many errors.

Found 94 errors in 27 files (checked 218 source files)

openhands-mypy.txt

We should examine why pre-commit is not catching errors, because our ci pipeline also relies on pre-commit.

It seems that the pre-commit yaml has version v1.9.0, while our pyproject.toml has 1.14.1. Could that be the issue?
