Caught error trying to update branch: Resource not accessible by integration

[lucacome]

Seems like autoupdate is not able to update PRs from a fork?
It fails to update all the PRs coming from forks, with: Caught error trying to update branch: Resource not accessible by integration

Here's the full log from one of the PRs

  Evaluating pull request #1883...
  Checking PR ready state
  PR_FILTER=all, checking if this PR's branch needs to be updated.
  All checks pass and PR branch is behind base branch.
  Updating branch 'opentracing-update' on pull request #1883 with changes from ref 'master'.

Is there a way to at least exclude forks, so the workflow stops failing?

[chinthakagodawita]

Hey @lucacome - unfortunately this is expected as the Github token used by Actions won't have access to write to the fork (it's scoped to the repository that the Action runs on).

Good idea though, let me see if I can put something in to exclude forks.

[lucacome]

Thanks, that would be useful!
In the meantime, I changed the token to use a PAT (so it could trigger other workflows) and I noticed that the error changed

  Updating branch 'opentracing-update' on pull request #1883 with changes from ref 'master'.
  Attempting branch update...
  Error: Caught error trying to update branch: Must have admin rights to Repository.

Oh interesting I haven't see that happen before, what's your autoupdate config and what scopes does your PAT have access to?

[lucacome]

I didn't create that PAT but I think it's just write permission, this is the workflow https://github.com/nginxinc/kubernetes-ingress/blob/master/.github/workflows/autoupdate-pr.yml
