RestSharp deserialize JSON content(represent an object contains an byte array) error

Question

The Client side receives a formal JSON content \"{\\\"Id\\\":[1,2,3],\\\"Size\\\":56}\", but get an error in deserialization the byte array.

1 Error occurs

Answer 1

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.
