What you expected to see, versus what you actually saw

Expected

A pull request being created for the npm and yarn ecosystem.

What actually happened

After submitting the metrics, and creating a commit for workspace changes the updater hangs until timeout on git stash show - at least that is the last thing printed to the logs

Native package manager behavior

Also, this seems to have nothing to do with the package manager itself.

I investigated running dependabot locally.
LOCAL_GITHUB_ACCESS_TOKEN=*** bin/dry-run.rb npm_and_yarn ***/***

That worked without issue.

Same thing is happening here. I've disabled groups as a temporary fix.

We have the same - though looking back at logs this happened the first time two weeks ago and happens constantly now in some repositories. A few more details from a repo where the daily update fails now:

• last successful run was on December 18th
• image versions read from the logs
  • failed run runner image version: ´20241215.1.0´
  • successful runner image version: ´20241211.1.0´
• minor difference in the job configuration json
  • failing runs have "enable-shared-helpers-command-timeout": true in the experiments field object
  • successful runs don't have it

I can dig up other information if need be, not sure what would be helpful. Above were the obvious differences.
