Getting winrm.exceptions.InvalidCredentialsError: the specified credentials were rejected by the server

I am trying out SCVMM list vms method, but when i am running the code getting
File "/Users/rohsing2/.pyenv/versions/3.7.7/lib/python3.7/site-packages/winrm/transport.py", line 268, in _send_message_request raise InvalidCredentialsError("the specified credentials were rejected by the server") winrm.exceptions.InvalidCredentialsError: the specified credentials were rejected by the server

I am able to get information running command directly by importing winrm module stand alone
#ps_script = """ Get-SCVirtualMachine -All -VMMServer localhost """ #s = winrm.Session("http://x.x.x.x.:5985/wsman", auth=('test', 'test$@#123'), transport='ntlm',server_cert_validation='ignore') #r = s.run_ps(ps_script) #print(str(r.std_out))
my code is straightforward
system = SCVMMSystem(hostname='x.x.x.x', username='test', password="test$@#123",domain=somevalue", provisioning="xxxx") system.list_vms()
Do we need domain value , and provisioning value as standalone winrm code is able to get information without it.
value for domain is known but what will be value for provisioning field.

Start by reproducing the failure through SCVMMSystem.list_vms(), then inspect the SCVMMSystem constructor and compare its authentication arguments with the working winrm.Session example. Check how domain and provisioning are consumed and whether they alter the WinRM credentials. Done means the credential mismatch is explained and the required values or a confirmed code fix are documented.
