pydrive.auth.RefreshError: Refresh_token не найден

Я пытаюсь загрузить файл с диска Google с помощью pydrive. код изменен из Автоматизация процесса проверки pydrive

И это дает следующую ошибку.

$ python driveDownload.py a a.xls
Google Drive Token Expired, Refreshing
Traceback (most recent call last):
  File "driveDownload.py", line 26, in <module>
    gauth.Refresh()
  File "build/bdist.linux-x86_64/egg/pydrive/auth.py", line 369, in Refresh
pydrive.auth.RefreshError: No refresh_token found.Please set access_type of OAuth to offline.

Поэтому я следовал инструкциям в соответствии с stackoverflow здесь

Не удалось заставить его работать. Я пропустил что-то основное?

мои настройки .yaml ниже

client_config_backend: settings 
client_config:   
  client_id: ###
  client_secret: ###

save_credentials: True 
save_credentials_backend: file 
save_credentials_file: credentials.json

get_refresh_token: True

oauth_scope:
  - https://www.googleapis.com/auth/drive.file
  - https://www.googleapis.com/auth/drive.install

Я получаю следующую ошибку:
