So the issue here is the backend service. If the DELETE request is sent and an application/json response is expected, the backend must send valid JSON. An empty response is not valid JSON so jQuery gets it right by throwing an error. This was a recent addition/bug fix in jQuery to throw this error since that is the correct way to handle invalid JSON. The backend service needs to send something like [].

Thanks. I thought that the message body could be empty for the responses of DELETE requests. However as of jQ 1.9 empty responses are rejected.
