API диска Google возвращает 400 Bad request при использовании PageToken

Я пытаюсь получить доступ к файлам следующей страницы в Google Drive API v3. Но этот конкретный фрагмент терпит неудачу.

Я проверил https://stackoverflow.com/a/38479234/11705040, но мой запрос query_string="'{0}' in parents".format(item["id"]) в этом сообщении выглядит нормально.

temp = (
       self.service.files().list(
           q=query_string,
           pageToken=nextPageToken,
           pageSize=5,
           fields="nextPageToken, files(id, name, mimeType, size, parents, modifiedTime)",
       ).execute()
   )

Ошибка такая:

EDIT Добавление минимального воспроизводимого примера: эта проблема возникает, когда я пытаюсь выполнить запрос в подпапке
