Import from github fails
I'm running a gitlab omnibus installation (8.9.3) and when I try to import a larger project from github, the importer fails partially. Here are the results:
- code is imported
✅ - issues are imported
✅ - branches for pull requests with deleted branches have been recreated (but not for all)
- no pull requests have been imported
- created branches aren't deleted on github
We have >2k PRs on github and I have to delete >1k branches after each attempted import. First, I thought it has something to do with #17766 (closed), because I actually found two deleted branches that had two PRs each. But I couldn't reproduce the error with a minimal repository with similar duplicate PRs. I just don't get anywhere near what's going wrong. And I don't find anything in the log files. Where exactly can I find error messages on why the importer fails? If I could find what's going wrong, I could probably fix the problem and provide you with a more detailed error report.
