Ошибка Google AdManager getCurrentNetwork ()

Question

Я установил учетные данные менеджера объявлений.Я пытаюсь получить доступ к Admanager API, я получаю следующую ошибку.

from googleads import ad_manager
client = ad_manager.AdManagerClient.LoadFromStorage()
network_service = client.GetService('NetworkService', version='v201902')
current_network = network_service.getCurrentNetwork()

ошибка, с которой я сталкиваюсь:
