+
+          GitHub Actions will not run workflows when a branch is pushed by or a PR is opened by a GitHub Action. To work around this, try:
+
+          ```sh
+          git branch -D update_flake_lock_action
+          git fetch origin
+          git checkout update_flake_lock_action
+          git commit --amend --no-edit
+          git push origin update_flake_lock_action --force
+          ```
