Unable to delete AppUser on CUCM through Python.

[himanshu87]

I am able to add Application user to CUCM using python but i am unable to delete it. Here is the code snippet:

client = Client(wsdl,location=location, username=AXL_USER, password=AXL_PASS, plugins=[ImportDoctor(imp)])
if action=='Add':
    result = client.service.addAppUser(appUser={'userid':user,'password':passw, 'associatedGroups':{'userGroup':[{'name':grp}]}})
if action=='Delete':
     result = client.service.removeAppUser({'userid':user})

Error from CUCM server:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://www.cisco.com/AXL/API/10.5" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<ns1:Body>

</ns1:Body>
</SOAP-ENV:Envelope>

Please help me on this error.
