Mergify failed to merge the pull request: resource not accessible by integration

[Nun-z]

Mergify is failing to automatically merge pull requests.

Here is one of the pull requests in question: https://github.com/Nun-z/RetroArch/pull/40

It's because Mergify have not been allowed to commit to your repository. Maybe you have activated the Branch Protection and Mergify is not allowed to merge Pull Request. See: https://docs.mergify.io/faq.html#mergify-is-unable-to-merge-my-pull-request-due-to-my-branch-protection-settings

[Nun-z]

I have not activated branch protection for this repository.

GitHub doesn't give us more information about which setting blocks Mergify to merge this PR. Mergify call pull request merge API on your behalf and this is forbidden by GitHub. Usually, this is due to a change in .github/workflows or a miss-configured Branch Protection, or Mergify just uninstalled. I don't known other setting that triggers this restriction.

Does Allow merge commits is enabled in your repository settings?

[Nun-z]

Allow merge commits is enabled. Is it relevant that this is a public fork of a public repository? None of the other solutions I've tried have worked due to that fact. Only read access is given for the other things I've tried.

Edit: note that I am trying to merge pull requests from the repositories I have forked.
