Error: "Pull request is in unstable status"

[LucasForster]

Hi,

hope it's okay to ask for support this way. I've set up a workflow using this action to enable auto-merge on all pull requests from dependabot as shown in the readme. Unfortunately, the runs fail with the above error message.

I'm not quite sure what "unstable status" refers to, as I could neither find it in the source code of this action nor in the GitHub Docs 🤷🏻‍♂️ My first thought ran to some kind of timing issue, but re-running the workflow after the pr had been open for some time didn't yield another result.

I'm pasting my workflow file and debug log below – any ideas would be appreciated 👍🏻

Thanks

If you haven't resolved your issue by now, you may want to take a look at https://github.com/peter-evans/enable-pull-request-automerge/issues/355. Same error, similar workflow, but with a discussion of possible solutions.
