Fails to merge more than 50% of the time

[snowe2010]

This action fails to merge quite a lot, with a message similar to this:

where it tries over and over to merge, even stating that it has the pull request number, but never merging. We always have to merge it manually. Thing is, this doesn't happen every time. Only most of the time.

Can you maybe try with debug output as described in the README? Maybe it will show some more info

[nopeless]

@pascalgn I'm not sure whether you will agree with me but I think debug should be on by default

[ffjdm]

I had the same error all the time and needed to add the following:

    permissions:
      contents: write

[pascalgn]

I think this is maybe fixed with the suggestion from ffjdm. However, it's a long time since there was some activity in this issue, so I will close it for now. If you have any new information or need any help, feel free to reopen this issue!

[snowe2010]

@pascalgn sorry, it takes quite a long time to get back to stuff with all the things I'm working on. I'll reopen/comment again when I find time to take a look back at these errors.

I'm back to looking at this and I've turned on TRACE logging. I'm able to see that it is able to find the PR just fine:

That's if I use a PAT. If I use the GITHUB_TOKEN with permission: write-all which sets all permissions to write then instead I get a Resource not found error:

The logs here don't seem very helpful... No error codes or messages.
