WCF wont accept JSON request

I have this code submitted to the server:

var obj = { "param": { "WithdrawalRequestId": window.Xrm.Page.data.entity.getId()} };
    $.ajax({
        type: "POST",
        dataType: "json",   
        data: JSON.stringify(obj),

        url: crmConfig.service + '/WithdrawRequestService.svc/ExecuteWithdrawalRequests/',

    });

the actual content that went to the server is:

{"param":{"WithdrawalRequestId":"{628E2E3A-283A-E311-B658-005056B7032A}"}}

The interface: 

 [OperationContract]
        [WebInvoke(Method = "POST",
            RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json,
            BodyStyle = WebMessageBodyStyle.Wrapped,
            UriTemplate = "/ExecuteWithdrawalRequests/")]
        void ExecuteWithdrawalRequests(GuidParameter param);

The GuidParameter class:

[DataContract]
public class GuidParameter
{
    [DataMember]
    public Guid WithdrawalRequestId { get; set; }

}

I am getting the following error:

The server encountered an error processing the request.

The exception message is 'The incoming message has an unexpected message format 'Raw'.
The expected message formats for the operation are 'Xml', 'Json'. This can be because a WebContentTypeMapper has not been configured on the binding.
See the documentation of WebContentTypeMapper for more details.

And this is the chrome output:

Add contentType: "application/json,

var obj = { "param": { "WithdrawalRequestId": window.Xrm.Page.data.entity.getId()} };
    $.ajax({
        type: "POST",
        dataType: "json",   
        data: JSON.stringify(obj),
        contentType: "application/json",
        url: crmConfig.service + '/WithdrawRequestService.svc/ExecuteWithdrawalRequests/',

    });
