Can't enable auto-merge for this pull request about fetch-metadata HOT 5 CLOSED

@bennycode - your action isn't actually using fetch-metadata (it's ignoring the output) - so it's equivalent to:

name: Dependabot auto-merge
on: pull_request_target

permissions:
  pull-requests: write
  contents: write

jobs:
  dependabot:
    runs-on: ubuntu-latest
    if: ${{ github.actor == 'dependabot[bot]' }}
    steps:
      - name: Enable auto-merge for Dependabot PRs
        run: gh pr merge --auto --squash "$PR_URL"
        env:
          PR_URL: ${{ github.event.pull_request.html_url }}
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

The error you're getting is being thrown by the github cli. I see you already posted about this cli/cli#3660 - if you got an answer on how we can update our example workflow to address this issue, please let me know.

@bennycode Did you resolve this issue? I am facing the same. In my repo, I have branch protection enabled with:

1. Require approvals
2. Require status checks to pass before merging
3. Restrict who can push to matching branches

My latest attempt (ampproject/amp-wp#6975) is to wait to run gh pr merge --auto until after all of the checks have passed but before I run gh pr review --approve. Not sure yet if it works.

@bennycode Does using a personal access token solve the issue?

from fetch-metadata.

I added a personal access token but I am still seeing this error:

gh pr merge --auto --squash "$PR_URL"
shell: /usr/bin/bash -e {0}
env:
PR_URL: ***
GITHUB_TOKEN: ***
Message: Can't enable auto-merge for this pull request., Locations: [{Line:1 Column:72}]
Error: Process completed with exit code 1.

I got it working in my personal public repository (implementation, proof that it works) but it doesn't work in my org's private repository (that uses the same YML config and has a personal access token configured in GitHub Secrets). 😢

Phew! I just found the issue. I ran into the "Can't enable auto-merge for this pull request" problem because auto-merge wasn't activated in my repo. After activating the "Allow auto-merge" feature in my repository settings it worked:

This made the GitHub Actions bot do the following:

Here is my final config:

name: Dependabot auto-merge

on: [pull_request_target]

permissions:
  pull-requests: write
  contents: write

jobs:
  dependabot:
    runs-on: ubuntu-latest
    if: ${{ github.event.pull_request.user.login == 'dependabot[bot]' }}
    steps:
      - name: Enable auto-merge on PR
        run: gh pr merge --auto --squash "$PR_URL"
        env:
          PR_URL: ${{ github.event.pull_request.html_url }}
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
      - name: Approve PR
        run: gh pr review --approve "$PR_URL"
        env:
          PR_URL: ${{github.event.pull_request.html_url}}
          GITHUB_TOKEN: ${{secrets.GITHUB_TOKEN}}

It actually works without "dependabot/fetch-metadata". I thought I needed "dependabot/fetch-metadata" because it was listed here. I also didn't knew that the secrets.GITHUB_TOKEN is something very special and not just a secret that you setup yourself in the "Action secrets" section of your repository settings.

Thanks to everyone who has helped!!

@brrygrdn: Can the "Can't enable auto-merge for this pull request" error message be improved in GitHub's cli to give a hint that auto-merge must be enabled on repository-level?
