When a get the token from the web service, the result json have to be deserialized and converted to DataTable. I can't do it using Utility Json VBO, because it does not find some objects like JavaScriptArray or JavaScriptObject, so i am trying to write my own code. The json is like: { "access_token":"token", "token_type":"type", "expires_in":111111, "userName":"the username", ".issued":"a date", ".expires":"a date" } Using JsonConverter.Deserialize(json, Datatable) fails with error: "unexpected json token when reading datatable. expected startarray got startobject ...".   Any idea to solve it?   Regards.
