Failed to merge PR: Resource not accessible by integration

[lukejgaskell]

Description

Running into an issue where the action intermittently is unable to merge the pull request. It complains about the resource not being accessible from the integration (Failed to merge PR: Resource not accessible by integration).

Setup

• Pull Requests are coming from forks, but that shouldn't matter as we are using the pull_request_target event.
• We run an auto approve step and then an auto merge. The auto merge ends up failing all retries and returns the following.

Has anyone seen this issue? Is there a certain way a pull request could be created from a fork that might cause this?

I'm facing the same issue. Here is my yaml file :

name: automerge check

on:
  pull_request:
    types:
      - labeled
  check_suite:
    types:
      - completed

permissions:
  contents: read
  pull-requests: write

jobs:
  automerge:
    runs-on: ubuntu-latest
    steps:
      - name: automerge
        uses: "pascalgn/[email protected]"
        env:
          GITHUB_TOKEN: "${{ github.token }}"
          MERGE_LABELS: ":rocket: Ready to Merge"
          MERGE_COMMIT_MESSAGE: "pull-request-title"
          UPDATE_LABELS: ":rocket: Ready to Merge"
          UPDATE_METHOD: "rebase"
          MERGE_FORKS: "false"

It was working fine before I added the permissions part. Anyone has an idea ?

Works for me: Change the trigger event from pull_request to pull_request_target

Have same problem, Not work on forks?

I had the same issue, it fixes when you use a PAT with permissions to manage PRs

I met this problem and finally found that the GITHUB_TOKEN token does not exist. You can check whether the secrets.GITHUB_TOKEN exists or whether there is an error. @mmiranda @totoprayogo1916

I found the solution: Go to the settings of your repo, actions, general. Then change the permission to read and write, and allow it to open and approve pull requests.
