            One or more files did not conform to the formatting. Maybe you did
            not run 'pre-commit' before committing, or your version of
            'clang-format' or 'prettier' has an incompatibility with the ones
            used here (see the "Check configuration" step above).

            Run 'pre-commit run --all-files' in your repo, and then commit and
            push the changes.
