Apparently invalid "Missing base report"

Hi. I realized that there are a lot of threads here about coverage not being processed properly and I read at least some of them, but wasn’t able to find a solution, so here we go.

Description

On our GitHub Repo a recent PR at some point had issues with reporting coverage. While coverage was handled correctly for this commit, it wasn’t for the next one in the same PR. When comparing the failing commit to the parent it tells me “Missing base report.” even though the parent did have a successfull coverage upload.

Afterwards none of the commits to the PR got coverage reports and I also wasn’t able to get them to work with new PRs based on the same branch/branches forked from it.

I had hoped that the problem would resolve after merging the PR, but now we have the same problem on master.

This is somewhat similar to the thread here, though the fix of upgrading the codecov package doesn’t apply has our CI always fetches the latest version from pypi.org.

I’d be happy for any advice or hints on what to look for. If I can’t get it to work again, I guess I’ll have to re-setup codecov as reported here, but ofc I’d like to avoid that.
