Я следую руководству sentdex по созданию чат-бота с использованием комментариев reddit и загрузил месяц комментариев в виде файла .bz2.
Когда я запускаю код, указанный ниже, я получаю сообщение об ошибке
Traceback (most recent call last):

Спасибо за ваше время!
PS Извините, если я задаю глупый вопрос, я довольно новичок в sqlite и json
