Invalid JSON response but contain no response data when checked

I created a SCRUD system by using Jquery JSON and DataTables but it returned an invalid JSOn response when i try to load my table. When i try to inspect for error it show This request has no response data available.Im sorry if it is a stupid mistake but i cant seem to find the error. This is is the link to the debug project demo code:

debug.datatables.net/amajom

The debug trace shows that the server isn't returning anything (which indeed is not valid JSON).

How are you checking it to see that it does contain data?
