The syntax around cobertura changed in a recent GitLab release which I guess was recently integrated into Heptapod - https://gitlab.com/gitlab-org/gitlab/-/issues/361615#note_937496084
The remaining issues with CI seem related to pytest, it appears they've removed
py as a dependency as the library has been somewhat retired (ref. https://github.com/pytest-dev/pytest/pull/10396 and https://pypi.org/project/py/)
It seems there's a fair bit of py.path used throughout the code and their proposed fix is to swap that to pathlib. I can make those changes or we can add
py as a dependency, either would fix it.
