Почему мой фрагмент кода файла JSON работает, но полная загрузка JSON не работает ⇐ Python

[Anonymous]

У меня есть фрагмент файла JSON, который я нормализую и использую Record_path с мета-параметрами в других столбцах, и он работает нормально, но когда я загружаю весь файл, я получаю ключевую ошибку. Ниже приведен мой код для загрузки фрагмента и полной загрузки файла JSON.
Фрагмент работает
