Json deserialize error AggregateException c# - json

Question

I am getting an error trying to move a DataSourceResult from one web service to another... the client calls web service A which resides on our web server. We then make a call to web service B which resides on our db server. The intent is that web service A adds certain sensitive data to the call, that we want hidden behind our firewall... then the call gets handled by web service B, gets a DataSourceResult, and seems to serialize it just fine... note I am using the same set of serilization properties to bot serialize and deserialize, I am just not showing the call to serilize here for brevity. When I go to deserialize this, I get a System.AggregateException - thrown on line "return formatter.ReadFromStreamAsync(typeof(T), stream, null, null).Result as T;" of my deserialization code... any ideas? anything would be much appreciated :)
Serilize code:
string Serialize<T>(MediaTypeFormatter formatter, T value)
{
// Create a dummy HTTP Content.
Stream stream = new MemoryStream();
var content = new StreamContent(stream);
/// Serialize the object.
formatter.WriteToStreamAsync(typeof(T), value, stream, content, null).Wait();
// Read the serialized string.
stream.Position = 0;
return content.ReadAsStringAsync().Result;
}
Deserialize code:
T Deserialize<T>(MediaTypeFormatter formatter, string str) where T : class
{
// Write the serialized string to a memory stream.
Stream stream = new MemoryStream();
StreamWriter writer = new StreamWriter(stream);
writer.Write(str);
writer.Flush();
stream.Position = 0;
// Deserialize to an object of type T
return formatter.ReadFromStreamAsync(typeof(T), stream, null, null).Result as T;
}
Json Object / settings being passed into methods:
var json = GlobalConfiguration.Configuration.Formatters.OfType<System.Net.Http.Formatting.JsonMediaTypeFormatter>().FirstOrDefault();
json.SerializerSettings.Formatting = Formatting.None;
json.SerializerSettings.DateFormatHandling = DateFormatHandling.IsoDateFormat;
json.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Serialize;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
json.SerializerSettings.NullValueHandling = NullValueHandling.Include;
json.UseDataContractJsonSerializer = false;
DataSourceResult result = Deserialize<DataSourceResult>(json, loansJson);
I have this string I try to deserialize and it throws this
