For the context I'm trying to update a file through the GitHub API. Everything was fine until I tried to update the reference.
According to the doc, below are the requests I forged and their returns.
If anyone has an idea, I did find nothing to make it work.
$ curl -i -XPATCH -d '{"sha": "69d0a253406585d8faf616ce3ae0ff2453b346d7"}' -H "Authorization: token AUTH-TOKEN" https://api.github.com/repos/Trax-air/TraxIT/git/refs/heads/ci-migrate-quay

I tried to update the reference by itself, it worked:

This may be due to caching. I asked to Github support and here is their answer:
Thanks for reaching out. The commit in question (69d0a253406585d8faf616ce3ae0ff2453b346d7) doesn't exist in that repository, so you're not allowed to update the branch to point to it.
As far as I can tell, it did exist in the repository at some point, but was pruned because it was no longer reachable. I think the API was telling you that it still exists in the repository due to caching.
I just cleared our caches and I think you should see that it's no longer available if you try to fetch that commit. I'm sorry for the confusion about that -- I'll ask the team to investigate why this caching problem happened.
