git_client.create_repository() Failing with msrest.exceptions.SerializationError

I am trying to create a git repository using the azure devops python module.

Here is the script I am using

personal_access_token = 'xxxxxxxxxxxxxxxxxx'
org_url = 'https://dev.azure.com/xxxxxxxxxxxxxxxxxxxxs'
project_name = 'testProject'

credentials = BasicAuthentication('', personal_access_token)
connection = Connection(base_url=org_url, creds=credentials)

git_client = connection.clients.get_git_client()

git_client.create_repository("repotest", project=project_name, source_ref=None)

The create_repository command is failing with the following error:

Tái hiện script được cung cấp và kiểm tra entry point create_repository trong azure/devops/v7_0/git/git_client_base.py quanh dòng 2986, sau đó lần theo lỗi tuần tự hóa model qua msrest/serialization.py. Được xem là hoàn tất khi cùng lời gọi tạo repository hoàn thành mà không có SerializationError đã báo cáo; issue không xác định file kiểm thử nào.
