We are using SonarQube developer 7.7 and PR Decoration starting failing after git was upgraded to version 3.3. SonarQube is updated with the scanning on the branch, but the check in git is in waiting state and never completes.
Your version is past EOL. You should upgrade to either the latest version or the current LTS at your earliest convenience. Your upgrade path is:
7.7 → 7.9.6 → 8.9.8 → 9.4 (last step optional)
If your error persists after upgrade, please come back to us. I suspect that the way PR decoration was implemented in SonarQube v7.7 (a non-LTS version released in March 2019, over 3 years ago) is no longer compatible with GitHub Enterprise 3.3. Out of curiosity, what version were you on before?
We are in the process of upgrading Sonar to 7.9->8.9, but was hoping for a short term solution to this issue, other than telling our end users they’ll need to disable decoration for a couple months. I don’t know the previous version of Git and we are also going to see if anything changes with the git app or possibly a git date/time issue.
