无法读取null jQuery数据表的属性“错误”

Question

在数据表加载期间出现错误“未捕获的TypeError：无法读取null的属性'error'”。以下是ajax调用并填充表的代码。该错误似乎是jquery数据表中的内部错误。如何检查返回的ajax响应中的空值

table = $('#data-table').DataTable({
            destroy: true,
            responsive: true,
            serverSide: false,
            autoWidth: false,
            paging: true,
            filter: true,
            searching: true,
            stateSave: true,
            scrollX: true,
            displayLength: 10,
            language: {
                "search": "Filtrer: "
            },
            ajax: {
                url: '/Observer/GetActiveClientsByFloor',
                type: 'POST',
                data: {
                    FloorId: floorId,
                    TypeId: typeId
                },
                dataSrc: ''
            },
            columns: [
                {
                    title: 'Zone',
                    data: 'LastKnownZone',
                },
                {
                     title: 'SSID',
                     data: 'ssId',
                },
                {
                    title: 'Status',
                    data: 'Statut',
                },
             
            ],
            
            createdRow: (row, data, dataIndex, cells) => 
            {

                const selectedRowProfileId = $('#selectedRowProfileId', window.parent.document).val();

                

                }
            },

            initComplete: function (settings, json) {

                clients = json;
                console.log(clients);
                if (clients.length !== 0) {

                    clients.forEach(client => {

                       


                    });

                }

            }
        }).order([[1, 'asc']]).draw(false);
