[jquery-datatables] DataTables warning: Requested unknown parameter '0' from the data source for row '0'

Make sure that the column names are the same. They are case sensitive. Here, in my case, i got this error when the column names of my model are in capitalzed and i used all the lower case letters in the data of ajax request.

So,i resolved by matching the column names exactly the same way as the existing model names.

DataTable Binding

$("#Customers").DataTable({
            ajax: {
                url: "/api/customers/",
                dataSrc: ""
            },
            columns: [
                {
                    data: "Name",
                    render: function (data, type, customer) {
                        return "<a href='/customers/edit/" + customer.Id + "'>" + customer.Name + "</a>";


                    }

                },
                {
                    data: "Name"
                },
                {
                    data: "Id",
                    render: function (data) {
                        return "<button class='btn-link js-delete' data-customer-id=" + data + ">Delete</button>";
                    }
                }
            ]
        });

Web API Method:

  public IEnumerable<Customer> GetCustomers()
        {
            return _context.Customers.ToList();

        }

My Model:-

 public class Customer
    {
        public int Id { get; set; }

        [Required]
        [StringLength(255)]
        public string Name { get; set; }        

        [Display(Name="Date Of Birth")]        
        public DateTime? BirthDate { get; set; }


        public bool isSubscribedToNewsLetter { get; set; }

        public MembershipType MembershipType { get; set; }

        [Display(Name="Membership Type")]
        [Required]
        public byte MembershipTypeId { get; set; }
    }

so here in my case, iam populating datatable with columns(Name,Name,Id).. iam duplicating the second column name to test.
