Error : TypeError: '>' not supported between instances of 'int' and 'NoneType'

報告されたスタックトレースを手がかりに、_vendored/pydevd/_pydevd_bundle/pydevd_frame_utils.py から始め、map_columns_to_line と _utf8_byte_offset_to_character_offset を追ってください。提供された Python 3.12 および debugpy のコンテキストを使って失敗を再現し、次にそれを引き起こす入力を特定して、その入力に対するテストカバレッジを追加してください。そのケースで TypeError が発生しなくなれば完了です。
