title: Derserializing Json Error : Unable to cast object of type 'Newtonsoft.Json.Linq.JObject' to type 'Newtonsoft.Json.Linq.JArray'
body: <p>I am trying to deserialize the Json object and it is throwing me the error  Unable to cast object of type 'Newtonsoft.Json.Linq.JObject' to type 'Newtonsoft.Json.Linq.JArray'.</p>
  
  <p>The error is surely  the new piece below as before adding , it was de-serializing correctly. I think it could be StressTestResults which has key value pair values and probably not an array.</p>
  
  <p>New Json added that led to the error above</p>
