jQuery's $.ajax() function will yield a JavaScript object if the response is JSON so I believe the error you're seeing is a result of trying to parse a JavaScript object and not a string as you're expecting. In the callback you're providing to the done function, inspect data and you'll find that it's an object and there is no need to JSON.parse the result.
