Ran these in shell (with actual params):

set TESTLINK_API_PYTHON_DEVKEY=[Users devKey generated by TestLink]
set TESTLINK_API_PYTHON_SERVER_URL=http://<url>/testlink/lib/api/xmlrpc.php

and getTestCase gives this error:

TypeError: ProxiedTransport.send_request() takes 4 positional arguments but 5 were given

Log:
