                    git commit -m "Add ${file_name}"

Trial

If I remove

                    git config --global user.email "[email protected]"
                    git config --global user.name "GitHub Actions"
                    git commit -m "Add ${file_name}"

it can works fine

Another issue

If it all works fine, how can I check the generated file as my expected?
