Wcf request is always coming with null parameters

Question

I am trying to call through a REST request in SOAPUI a WCF service running in localhost from Visual Studio. My problem is that the request is coming with its properties to null. Here is the JSON of the request:

    { 
   "request":{ 
      "order":{ 
         "uuid":"FEAEBDE7-8328-4E39-99F3-CD83F7405573",

         ],
         "token":"971857af7a43f021059fb2c7f62cb90e601fafe9a133062d0bca224bf6fc33899b68092288772331f33c310e422c51b0ca9bfb7bf7a6cad3af30473c992a7776",

         "uuid":"756CC6A3-933F-424B-B53B-39EC52118E7D"
      }
   }
}

What am I doing wrong? I am not able to find why the request message is coming with both Order and Client null.

Answer 1

Finnally I found the reason why it did not work. I had to specify the namespace for the data contract.

   [DataContract (Namespace="my_namespace"]
        public partial class Source{}
