AzureDevOpsAuthenticationError: The requested resource requires user authentication: https://dev.azure.com/myorg/_apis

I followed the sample code:

        credentials = BasicAuthentication(username=user, password=pat)
        self.connection = Connection(base_url="https://dev.azure.com/myorg/", creds=credentials)
        testClient = self.connection.clients.get_core_client()

But I get exception. Did I miss something?

從 Connection(...) 和 BasicAuthentication 範例開始，接著沿著 azure/devops/connection.py 和 azure/devops/client.py 中的 get_core_client 追蹤到堆疊追蹤中顯示的 resource-area 請求。重現驗證失敗，並找出缺少的設定或 endpoint 詳細資訊；當範例成功完成驗證，或已記錄必要的修正時，即表示完成。
