Error: Codecov: Failed to properly upload: The process '/Users/runner/work/_actions/codecov/codecov-action/v3/dist/codecov' failed with exit code 255

The issue is usually fixed after running the failed job again.

Proposed solution

I believe the issue can be fixed:

1. Adding a codecov token
2. Updating the github action to use the token

The reason for that, is based on the following comment where other users seems to face the same issue and even codecov documentation doesn't mentioned the use of the token when the repo is public, this seems to fix the issue
