I'm attempting to add a response-time poller to my recently created node, and getting an error message I don't understand. it tells me that 'properties' must not be null. Here is the soap message sent (edited for readability, and to remove all the excess namespace declarations...)
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope>
<soap:Body>
<tns:Create>
