jquery DataTable sometimes showing error on load

Question

I am showing a list using jquery DataTable on page load, it's working perfectly, but sometimes it's showing error immediately after requesting page. On request, i fetch data from db and passed to DataTable. I shared error screenshot. plz find attachment.

Sachin Singh · Answer

it means on page load you are not getting json data that is specied on Ajax request which causing the error. better is to show your ajax code where you are binding datatable. and also the backend code.
