im using yajrabox datatables for laravel and I got response from server with ajax.

The question is how to print a default value when a record is null in our database and it is join column (creator_id column in table)

now when database record is null, it returns error in alert that it said [Undefined index]

my Jquery code is

<script>

    $(function() {

        $('#users-table').DataTable({

            processing: true,

            serverSide: true,

            oLanguage: {

                sProcessing: "<img width='300px' src='{{asset('123.gif')}}'>"

            },

            ajax: '{!! route('show_product_type_list.data') !!}',

            columns: [

                {   data: 'creator.fullname',

                    name: 'creator.fullname', 

                    defaultContent: "",

                    orderable: true

                },

                { 

                  data: 'type_name',

                  name: 'type_name' 

                },

                @can('product-type-detail')

                { 

                 data: function($type) { 

                     return '<a href="/admin/product/type/detail/' + $type['id'] + '" 

                                class="btn btn-primary btn-icon-anim btn-square">

                            <i class="fas fa-eye"></i>

                          </a>

                         </a>' },

                 name: 'view', sortable: false },

                @endcan

            ]

        });

    });

</script>

if i set defaultContent: "" and sortable: false code has not error but sorting has been disabled
