Python 2.7 Adwords API UserListService在调用mutate时导致属性错误

我正在使用Google AdWords API userListService添加一个新的用户列表，我已经通过了所有必需的输入，并且成功创建了adword客户端实例

但是在调用mutate方法时，它抛出了一个属性错误 “AttributeError:类HttpTransport没有属性'\u HttpTransport\u get\u request\u url'”

请找到StackTrace:

import uuid
from googleads import adwords
from googleads import oauth2

def main(client):
    # Initialize appropriate service.
    user_list_service = client.GetService(
        'AdwordsUserListService', version='v201702')

    # Construct operations and add a user list.
    operations = [
    {
        'operator': 'ADD',
        'operand': {
            'xsi_type': 'BasicUserList',
            'name': 'Mars cruise customers #%s' % uuid.uuid4(),
            'description': 'A list of mars cruise customers in the last 
    year',
            'membershipLifeSpan': '365',
            'conversionTypes': [
                {
                    'name': ('Mars cruise customers #%s'
                             % uuid.uuid4())
                }
            ],
            # Optional field.
            'status': 'OPEN',
            }
        }
    ]
    result = user_list_service.mutate(operations)

if __name__ == '__main__':
    CLIENT_ID = 'xxx'
    CLIENT_SECRET = 'xxx'
    REFRESH_TOKEN = 'xxx'
    DEVELOPER_TOKEN = 'xxx'
    USER_AGENT = 'xxx'
    CLIENT_CUSTOMER_ID = 'xxx'
    oauth2_client = oauth2.GoogleRefreshTokenClient(CLIENT_ID, CLIENT_SECRET, REFRESH_TOKEN)
    adwords_client = adwords.AdWordsClient(DEVELOPER_TOKEN, oauth2_client, USER_AGENT,client_customer_id=CLIENT_CUSTOMER_ID)
    main(adwords_client)

这是我的代码：

from googleads import oauth2

    # Initialize appropriate service.
    user_list_service = client.GetService(
        'AdwordsUserListService', version='v201702')

    # Construct operations and add a user list.
    operations = [
    {
        'operator': 'ADD',
        'operand': {
            'xsi_type': 'BasicUserList',
            'name': 'Mars cruise customers #%s' % uuid.uuid4(),
            'description': 'A list of mars cruise customers in the last

            ],
            # Optional field.
            'status': 'OPEN',
            }
        }
    ]
    result = user_list_service.mutate(operations)
