Sign Commits of GitHub Actions

[MrZep]

Hello! I am looking for a way to sign the commits for my GitHub Actions which suppose to commit files the files created in the branch where I'm running my pipeline. On my Repo is a rule created which only allows verified commits.

Maybe I have imported the key pair at the wrong place. I dont know. Please help!! 😅

This is what my relevant steps of my pipeline look like: (Do not be suprised about some things there, beceause I was troubleshooting quite a while without a result :( )

    - name: 1 file generator | Prepare GitHub Actions Signed Commit with GPG Key
        id: import-gpg
        uses: crazy-max/ghaction-import-gpg@v6
        with:
          gpg_private_key: ${{ secrets.BOT_GPG_PRIVATE_KEY }}
          passphrase: ${{ secrets.BOT_GPG_PASSPHRASE }}
          git_user_signingkey: true
          git_commit_gpgsign: true
      - name: 1 file generator | Terraform format and copy created files into branch
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        run: |
          gpg -K
          terraform -chdir=./.created_files/ fmt
          git config --global user.email "${{ steps.import-gpg.outputs.email }}"
          git config --global user.name "${{ steps.import-gpg.outputs.name }}"
          git remote set-url origin https://x-access-token:${{ secrets.GITHUB_TOKEN }}@github.com/${{ github.repository }}
          git add .
          git commit -S -m "Check-In created Terraform Files"
          git push
          # echo "The monitoring-baseline.tf has changed since the last run and will now be overwritten in the ./.created_files folder"

This is my error:

Does anyone have an Idea why my Pipeline keeps failing?
