RestSharp deserialize JSON content(represent an object contains an byte array) error
JsonDeserializer from RestSharp can not deserialize array. Instead of byte[] use List<byte>. For more information see https://github.com/restsharp/RestSharp/wiki/Deserialization
I have run into this issue, too. My solution was to use RestSharp to perform a raw execute and use Json.NET to deserialize the result:
var response = client.Execute(request);var keyResponse = JsonConvert.DeserializeObject<key>(response.Content);keyResponse should now be an instance of your key class deserialized from the JSON content.
In addition to Chris Hogan's reply, I'd like to point out that I got this error when RestSharp incorrectly used the default serializer instead of the custom JSON.NET serializer I had assigned.
The reason for this was that I added a handler with content type application/json whereas the API I was getting the response from returned the content as text/json.
So by changing the AddHandler call to AddHandler("text/json", jsonDeserializer), I resolved the issue.
