Coveralls stopped working with no code changes in project

[superm1]

Recently fwupd CI started to break on any jobs that upload to coveralls.

We're using 3dfc556 and here is the failure in CI logs.

Here is an example failure: https://github.com/fwupd/fwupd/actions/runs/8877359982/job/24370866636?pr=7179

Here is one that passed (again no changes on our side for coveralls).

Maybe the same problem as #205 ? The confusing thing to me though is that both the pass and fail used 0.6.10 it looks like.

Double checked with --debug on the job added, and calling pip install coverage before running it doesn't change anything.

Run coveralls report --debug

Something must have changed in the container we use. I changed our job to upload artifacts including the coverage file and I see it it's missing data. Sorry for the noise!

Hi @superm1. No worries. Based on that error from our API, it means our integration (Coverage Reporter) sees a file, coverage.xml, in your environment but doesn't recognize the format and can't parse it.

If the format you're using is one of the formats we support, then this can be fixed by using the --format flag (or the format: input option if you're using the Coveralls GitHub Action), to specify the format of the coverage report(s) you want to upload.

For instance, given you're in python, if you've converted your .coverage file into XML format with the coverage xml command, then the specific XML format of your new coverage report will be Cobertura XML, and therefore you should use --format cobertura.

Using --format is not required in general, but is recommended since it will tell our integration (Coverage Reporter) that it should only focus on reports of that format and should ignore reports in other formats, which will prevent errors when you have duplicate reports in different formats in the same environment.
