I ran into this exact same error message. I tried Aditi's example, and then I realized what the real issue was. (Because I had another apiEndpoint making a similar call that worked fine.) In this case The object in my list had not had an interface extracted from it yet. So because I apparently missed a step, when it went to do the bind to the

List<OfthisModelType>

It failed to deserialize.

If you see this issue, check to see if that could be the issue.

For array type Please try this one    List lt MyStok gt  myDeserializedObjList    List lt MyStok gt  Newtonsoft Json JsonConvert DeserializeObject sc   typeof List lt MyStok gt       Please See here for details to deserialise Json

It looks like the string contains an array with a single MyStok object in it  If you remove square brackets from both ends of the input  you should be able to deserialize the data as a single object   MyStok myobj   JSON Deserialize lt MyStok gt  sc Substring 1  sc Length-2      You could also deserialize the array into a list of MyStok objects  and take the object at index zero   var myobjList   JSON Deserialize lt List lt MyStok gt  gt  sc   var myObj   myobjList 0
