Ошибка 404 при создании календаря с помощью Google Calendar Api

Я только что написал этот код, который должен проверять, существует ли календарь, а если нет, то создать его. Ну, он возвращает ошибку 404, когда я пытаюсь создать календарь, а календарь НЕ появляется. Любые идеи? Я удалил clientid, секрет, ключ приложения.
