[BUG] Coveralls does not report coverage

[niccokunzmann]

Describe the bug

Coveralls is supposed to generate a pull request summary. Currently, it breaks on main and on the pull requests.

To Reproduce

See main and the commits:

https://github.com/collective/icalendar/actions/runs/9751261758/job/26912463324#step:6:1

Error running coveralls: Could not submit coverage: 422 Client Error: Unprocessable Entity for url: https://coveralls.io/api/v1/jobs
Received 422 submitting job via Github Actions. By default, coveralls-python uses the "github" service name, which requires you to set the $GITHUB_TOKEN environment variable. If you want to use a COVERALLS_REPO_TOKEN instead, please manually override $COVERALLS_SERVICE_NAME to "github-actions". For more info, see https://coveralls-python.readthedocs.io/en/latest/usage/configuration.html#github-actions-support
Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.8.18/x64/lib/python3.8/site-packages/coveralls/api.py", line 298, in submit_report

    raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 422 Client Error: Unprocessable Entity for url: https://coveralls.io/api/v1/jobs

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

Traceback (most recent call last):
  File "/opt/hostedtoolcache/Python/3.8.18/x64/lib/python3.8/site-packages/coveralls/cli.py", line 98, in main

    return self.submit_report(json_string)

    raise CoverallsException(

/opt/hostedtoolcache/Python/3.8.18/x64/bin/coveralls

Expected behavior

I would like coveralls to

• run during PR and main builds
• provide a comment as it did before about the test coverage

Additional context

• Improve coverage report #644
• Make coverage report optional in case it fails to submit #664

coveralls is reporting coverage. #680 (comment)
