Export testcases from KIWI TCMS by python script does not work

问题

I have script for export some Testcases from KIWI TCMS system. Problem is, that script does not work. Script does not return anything. And second questions. What does it mean this: {'pk': 46490} Is it some filtr?

--------------------------------------- 
from tcms_api import TCMS
rpc_client = TCMS()
for test_case in rpc_client.exec.TestCase.filter({'pk': 46490}):
    print(test_case) 
--------------------------------------
