Hi ,
I am using datatables in my spring project and i am sending ajax call to the controller to fetch the data , and data is fetched from the controller when i debugged the code but is not able to show on the datatables because of the above error.

Here is the request code :

              table=$('#employee-table').DataTable({
            'serverSide' : true,
            'ajax' : {
                url : 'getallemployees',
                type : 'POST',
                contentType : "application/json",
                data: function ( d ) {
                    // Modify data into what is required by backend API
                    d.searchParam = d.search.value;
                    console.log(d.sEcho);
                    delete(d.search);
                    delete(d.columns);
                    delete(d.order);
                  return JSON.stringify(d);
                },
                dataSrc: "EmployeeEntries"
            },
            columns: [
              { data: 'username' },
              { data: 'firstname' },
              { data: 'role' }
            ],
            select: 'single',
            filter: true
        });

The error suggests that EmployeeEnteies might not be an array in the returned object, but without a test case or debug trace it is impossible to say. Can you please provide a link, per the forum rules.

p.s. The link for how to format code is shown just before the text input box.
