Я следовал учебнику https://developers.google.com/drive/api/v3/quickstart/nodejs и получил его, чтобы вывести список файлов на консоль, но когда я пытаюсь вернуть res.data.files, он выдает мне неопределенное значение и ошибки с: API возвратилошибка:
Ошибка: превышен суточный лимит для использования без аутентификации.Для продолжения использования требуется регистрация.
Пытался вернуть его из функции listFiles
