Hi ${{ steps.commit.outputs.name }},
Thank you for your modifications, that's great!
But sadly, our CI spotted some issues with it when trying to build it.
You can find more details there:
${{ github.server_url }}/${{ github.repository }}/actions/runs/${{ github.run_id }}
Status: ${{ needs.build.result }}
Initiator: ${{ steps.commit.outputs.committer }}
Commits: ${{ github.server_url }}/${{ github.repository }}/commits/${{ steps.commit.outputs.sha }}
Patchwork: ${{ steps.commit.outputs.series }}
Feel free to reply to this email if you cannot access logs, if you need
some support to fix the error, if this doesn't seem to be caused by your
modifications or if the error is a false positive one.
Cheers,
