Solution 1

UserBusiness appears to be null.
UserNotes appears to be null.
UserPreferences appears to be null.

With an object reference error, it probably means that one or more of these objects must be populated for the call to succeed.

Their can be multiple possibilities for universal error known as "Object reference not set to an instance of an object". :)

Check order of your nodes of XML matching with order of your DataContract Class properties. Because it wont deserialize if order is incorrect.

You can also have a look at my below Tip/Trick on the topic "Debug WCF REST Service".

Debug WCF REST Service.

Hope it should help to resolve your error.
