ASDF project CI/CD failure

I was looking at a merge request for ASDF, and it failed all the CI/CD tests. See, for example, https://gitlab.common-lisp.net/rbrown/asdf/-/jobs/103352 What's odd is that it looks like this failure isn't about anything failing, it's about CI/CD not being able to clone the git repo. ``` Getting source from Git repository 00:00 Gitaly correlation ID: 01K9DE5HXE6N8KDGC4YQ4ERFSV Fetching changes... Initialized empty Git repository in /builds/rbrown/asdf/.git/ Created fresh repository. fatal: unable to access 'https://gitlab.common-lisp.net/rbrown/asdf.git/': The requested URL returned error: 500 ``` Any idea what is going haywire here? Thanks! R
