HTTP 500 after repository mirroring

Dear GitLab Community Forum,

I’m having an issue with a self-hosted GitLab Instance and would be glad, if someone has an idea, how this could be fixed. Please find my description below.

In case there’s any information missing, that would be useful, please let me know and I will add it.

Problem to solve

Describe your question in as much detail as possible:

Steps to reproduce

1. Trying to setup a repository mirroring under Settings → Repository → Mirroring repositories
2. After confirming (creating) a new mirror repository, I keep getting a HTTP 500 Error
3. I made the mistake to add a repository in this format “https://gitlab.com/user/repository” without adding “.git” at the end

What is not working:

  • Access project directly via Project URL
  • Access “Committs”-Section, “Branches”-Section
  • Houskeeping actions (Archive project, Change path)

Workaround:

  • Access data via “Repository” tab

Versions

  • Self-managed

Versions

  • GitLab v16.11.5-ee

Configuration

Logs from /var/log/gitlab/gitlab-rails/production_json.log do look like the following:

Steps I took to resolve this:

- Look into the logs (obviously)
- Use API Call “https://gitlab.example.com/api/v4/projects/<project_id>/remote_mirrors” to display mirrored repositories.
Answer: “%[]” (None)
- Look into [Solved] Undefined Method - Error 500 and carry out “gitlab-rake db:migrate:status” (Result: all migrations are up)
- When carrying out “gitlab-rake gitlab:check” in the “Projects have namespace”-section, I do not see my private repository. Everything else is listed with a “yes” at the end.

Is there anything I do not see? Or anything I can do to solve this?

Thanks for taking the time to read through my problem! :blush:
