Error 415 while testing my wcf service

I have a Restful service that has this OperationContract

[OperationContract]
[WebInvoke(Method = "POST",
  ResponseFormat = WebMessageFormat.Json,
  BodyStyle = WebMessageBodyStyle.Wrapped,
  UriTemplate = "json")]
Response JSONData(Request request);

and configured in this way

The request object is formed in this way

[DataContract]
public class Query
{
    [DataMember]
    public string name { get; set; }

    [DataMember]
    public string birthDate { get; set; }
}

[DataContract]
public class Input
{
    [DataMember]
    public Query query { get; set; }

    [DataMember]
    public string login_username { get; set; }

    [DataMember]
    public string login_password { get; set; }
}

[DataContract]
public class Request
{
    [DataMember]
    public Input input { get; set; }
}

I created a small client to validate this request, and I also tested it with WCFTestClientand works great. If I try to access this through a violinist, although I get an error 415 Unsupported Media Type.

I tried this as follows

POST, http://localhost:8080/HostDevServer/SearchService.svc/json, HTTP/1.1

User-Agent: Fiddler
Content-Type: application/json;charset=UTF-8
Host: localhost:8080
Content-Length: 368

{ "input": { "login_password": "pass", "login_username": "login name", "query": { "birthDate": "", "name": "robert" } } }

I also tried to deploy this service and see if the violinist could access it, but everything became even more confusing, because now instead of receiving it 415I received a complaint 400about 'Reference to an object not set to an instance of the object.'and the small command-line client that I created will complain about the There was no endpoint listening atlocation of my service.
