    needs: deploy-check
    if: needs.deploy-check.outputs.triggered == 'true'
    steps:
      - name: get pull request ref

        uses: octokit/[email protected]
        with:
          route: GET /repos/:repository/pulls/:issue_id
          repository: ${{ github.repository }}
          issue_id: ${{ github.event.issue.number }}
        env:
          GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
