👋 In case it can help y'all isolate the cause in your case, one way these 503 can occur is if your running workflow jobs separately upload the same artifact name and path.

The risk of that is described in this project's README under Uploading to the same artifact:

Each artifact behaves as a file share. Uploading to the same artifact multiple times in the same workflow can overwrite and append already uploaded files:

[joshuapinter]

@solvaholic Yoooooo! I think that is our exact issue. We were uploading logs from multiple jobs with an artifact name that used the github.run_id, which is shared amongst all of the jobs. So if two or more jobs uploaded artifacts, they would be uploading artifacts with the same name. When done non-concurrently, this seemed to be just fine (I think). But perhaps when done concurrently, this was causing us to get 50x issues because the artifacts were becoming corrupt or having a conflict with two jobs writing to the same artifact/temp file.

I'm not 100% sure on this but your comment made me look at this again and think that this could be the issue. We're going to test out a solution where we use the github.job_id instead of the github.run_id to scope our log files per job and see if this issue reoccurs. I'll try and remember to post back here the results.

Thanks for commenting this and linking to that warning in the README. 🙏

@konradpabjan I just found your comment at https://github.com/actions/upload-artifact/issues/84#issuecomment-667256833. We're getting 500 errors fairly regularly. Up until today, we did have 3 jobs that were all sharing the same artifact name, which we realized was wrong. We have since fixed that bug in our workflow, but we are continuing to encounter 500 errors, such as in https://github.com/kcp-dev/kcp/runs/6264716798?check_suite_focus=true. Any chance you could take a look? Thanks!

We are also suffering from these errors. Ping @konradpabjan.

edit: Another process had one of the files being uploaded open simultaneously. This at least makes the issue occur more frequently if not the root cause. The error message should be improved at least.

v4 has shipped today https://github.blog/changelog/2023-12-14-github-actions-artifacts-v4-is-now-generally-available/

I recommend switching over as these classes of issues should no longer happen with the release

Would be nice to be able to do it but impossible on github enterprise....
