Error 500 while comparing large project and fork

Describe your question in as much detail as possible:

I’m submitting a drive-by doc change to gitlab. My tiny changes - a mere nit - is on me/gitlab at a branch named after me (he said, avoiding dumping a URL into the forum).

When I generate a merge request and/or compare I get a “Whoops, something went wrong on our end.” 500 Error when merging / comparing one specific branch.

  • What are you seeing, and how does it differ from what you expect to see?

Seeing 500 error page (no further info) - expecting to see merge or compare

  • Consider including screenshots, error messages, and/or other helpful visuals
  • What version are you on (Hint: /help) ? and are you using self-managed or

The current .

  • What troubleshooting steps have you already taken? Can you link to any docs or other resources so we know where you have been?

I’ve searched for similar tickets, but I’m at a loss as to where else to go for a 500 error.

Thanks for taking the time to be thorough in your request, it really helps! :blush:

For my case, I am able to compare but get a 500 when trying to submit a merge request.

The specific MR I was trying to create was from my old fork of gitlab-org/gitlab-ee to the current gitlab-org/gitlab project. I made sure to update the fork and make the diff minimal in commits and changes (1 line, 1 commit) but still get a 500.[source_branch]=qayshp-master-patch-98927&merge_request[source_project_id]=8281994&merge_request[target_branch]=master&merge_request[target_project_id]=278964&tab=diffs
