"Reference already exists" on GitHub import
Summary
Upon importing our Github repo, import fails with "Reference already exists".
Steps to reproduce
- Authorize GitLab on Github
- Import our repo from Github
- Import fails. Logs show "Reference already exists" error from Github API.
Unfortunately, this is a private repo, which I cannot provide a public copy of. We may be able to grant access to individual Gitlab developers to diagnose the issue.
Relevant logs and/or screenshots
