We have a Python repository on GitHub that we set up with SonarCloud using GitHub actions.
The sonarcloud action is correctly uploading the coverage report for the main branch, and we can see line-by-line coverage too.
However, coverage is not showing in PRs, neither in the summary page nor in the Code page (actually, no code is visible):
The analysis / scanner log is what’s output from the analysis command. Hopefully, the log you provide - redacted as necessary - will include that command as well.
