coveralls fails with "422 Client Error: Unprocessable Entity"

[andy-maier]

Since a few days, coveralls fails to upload from GitHub Actions as follows:

 coveralls --service=github
 shell: /usr/bin/bash -l {0}

The above exception was the direct cause of the following exception:

coveralls.exception.CoverallsException: Could not submit coverage: 422 Client Error: Unprocessable Entity for url: https://coveralls.io/api/v1/jobs

This happens on all Python versions we support (2.7, 3.5-3.11) and with and without --service=github specified.
The coveralls version is 2.1.2 for our minimum version runs and 3.3.1 for our latest version runs.

This started occurring only a few days ago. Before that, it ran fine.
The latest failing run with my attempts to fix it is: https://github.com/zhmcclient/python-zhmcclient/actions/runs/4839303086
The last run where it still ran fine is from 4/23 and is: https://github.com/zhmcclient/python-zhmcclient/actions/runs/4774941292

I could not identify any relevant package version changes between the last run that worked and now.

I tried the recommendation in #1435 (comment) but it did not help.

Sorry, wrong repo. This should have gone to TheKevJames/coveralls-python. Closing it.

All good, @andy-maier. We think this is actually being caused from our end right now and are looking for a fix.

We think it relates to the issue in #1708 but noticed that when that issue resolved for users of the Coverage Reporter and Coveralls Github Action, it did not resolve for users of coveralls-python.

I see you came back and opened #1710 about it, so we'll pick it up there.

We believe this issue has been resolved, but we are continuing to monitor:

If you are using the coveralls-python integration with Github Actions for CI, please let us know if the issue is not resolved for you: support@coveralls.io
