[otrs] Generic Interface with Python

I am attempting to use Python and SOAPpy as a requestor to the Generic Interface. However, I am having issues. This is the complete Python code for my test: http://pastebin.com/jD7jD5yv This is the SOAP request that it is sending out: http://pastebin.com/gUKc8np4 OTRS system log is reporting that it "Got no OperationType!" I am stuck and can't seem to find what I am missing. Can someone point me in the right direction? Thanks, Kris
