Getting an error while trying to test a plugin I'm writing, haven't seen this one before:

File "/home/jreed/.cache/pants/named_caches/pex_root/venvs/s/ec6445a5/venv/lib64/python3.9/site-packages/_pytest/config/__init__.py", line 1579, in parse_warning_filter
    category: Type[Warning] = warnings._getcategory(category_)  # type: ignore[attr-defined]
  File "/usr/lib64/python3.9/warnings.py", line 262, in _getcategory
    raise _OptionError("invalid module name: %r" % (module,)) from None
warnings._OptionError: invalid module name: 'pymysql'

This is the first time i'm trying pytest with pants on this container, wonder if it's possible that something is interfering
