Discussion Details

Please note an additional inconsistency:

GitHub sent a failure notification for workflow run #575, reporting that the build succeeded in 18 seconds but deployment failed after 10 minutes and 13 seconds.

However, the GitHub Actions API continued to report the same workflow as queued, with no jobs returned.

Please investigate this inconsistent state and clear any stale Pages deployment or workflow lock affecting repository radimventus/embed-engine.

The previous workflow #574 also completed its build successfully but failed during deployment after approximately 10 minutes.

I looked at the public run data for embed-engine and the two things you see fit together.

Run #575 does have jobs, they just don't show up in the default jobs list. GET /actions/runs/42810220302/jobs?filter=all returns all three: build finished in 18s, report-build-status passed, and deploy failed at 11:57:19 after running for 10m13s. Only the run record at the top never got its final status written, so it still says queued. That's on GitHub's side and you can't cancel or clear it, but it also doesn't block anything. Nothing waits on it.

The actual problem is the deploy step stopping at about 10 minutes in both #574 and #575. That's the deploy-pages timeout (timeout, default 600000 ms = 10 min). So the step gave up while Pages was still syncing files. Before that your runs took ~40s from start to finish, so something changed on 11-10. Either Pages was slow that day or the artifact got a lot bigger. The repo is around 300 MB, and with "Deploy from a branch" the whole task-72-fix-01 branch gets uploaded as the site.

What I'd do:

1. Push a new commit to task-72-fix-01 (an empty one works: git commit --allow-empty -m "redeploy" && git push). That gives you a fresh run, no need to touch #575. In a couple of other threads this week the next deploy went through once Pages recovered.
2. If deploy fails at 10 min again, it's probably the size. Switch Settings → Pages → Source to "GitHub Actions" and use your own workflow. Then you upload only the folder that is the site with actions/upload-pages-artifact (path: ./dist or whatever yours is), and you can give actions/deploy-pages more time with timeout: 1200000.

Can you check the log of the "Deploy to GitHub Pages" step in #575? If the last lines say "syncing_files" over and over, that's the case above.
