TypeError: object of type 'NoneType' has no len() when uploading coverage

Hi there!

We've noticed that since release 10.1.0 went out that our codecov upload github action is failing with the following stack trace

 Traceback (most recent call last):
  File "codecov_cli/main.py", line 97, in <module>

I suspect this is due to this change #625
I'm not very well versed in python but maybe len(None) isn't allowed?

Thanks @joseph-sentry ! I didn't have the python chops to help out :)

@thomasrockhu-codecov @joseph-sentry FYI, you should be able to mark the PyPI release as yanked to limit the damage.

UPD: I see it got yanked which is why there's no mass reports with this traceback.

Oh, I'm still seeing this in CIs because the actions download 10.1.0 from another hosting: https://github.com/ansible/awx-plugins/actions/runs/13437325559/job/37542819968#step:24:41.

Interestingly, there's some API that returns HTML in place of JSON: https://github.com/ansible/awx-plugins/actions/runs/13437325559/job/37542819968#step:23:45. But it's probably being hit on the action side, not the CLI project...

@thomasrockhu-codecov any chance to change “latest” to the previous version there too?

Looks like the workaround would be use_pypi: true (bypasses integrity checks) or version: 10.0.1.

@webknjaz hoping to get out a deploy that should fix this today

version: 10.0.1.

Apparently, it's version: v10.0.1: https://github.com/ansible/awx-plugins/actions/runs/13438098254/job/37545385409?pr=86#step:23:43.
