Pull Requests from outside contributors do not get the correct ref

[cellistigs]

Pull Requests from forks/outside contributors (not sure which) don't trigger the right pull in get_pull_request_ref action. In particular, look at the code here:

deploy:
    runs-on: ubuntu-latest
    needs: deploy-check
    if: needs.deploy-check.outputs.triggered == 'true'
    steps:
      - name: get pull request ref
        id: get_pull_request_ref
        uses: octokit/[email protected]
        with:
          route: GET /repos/{owner}/{repo}/pulls/{issue_id}
          owner: cunningham-lab
          repo: neurocaas
          repository: ${{ github.repository }}
          issue_id: ${{ github.event.issue.number }}
        env:
          GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}"

Later, we explicitly call fromJson(steps.get_pull_request_ref.outputs.data).head.ref as the output of this step, which will just get the ref for master. We need to find a way to reference the ref of the forking repo.

Play around with the first solution suggested here:
actions/checkout#455

Fixed. The solution was to get the head.sha attribute instead of the head.ref attribute.
