我在aiyp刷新dataTables表时遇到问题。当我运行下面的脚本时，我得到以下错误：

Uncaught TypeError: Cannot set properties of null (setting 'data')
    at sa (jquery.dataTables.min.js:37)
    at Tb (jquery.dataTables.min.js:108)
    at s.<anonymous> (jquery.dataTables.min.js:108)
    at s.iterator (jquery.dataTables.min.js:100)
    at s.<anonymous> (jquery.dataTables.min.js:108)
    at Object.reload (jquery.dataTables.min.js:103)

    at Object.fireWith [as resolveWith] (jquery-1.9.1.min.js:3)
    at k (jquery-1.9.1.min.js:5)`

脚本示例

var recordid;
var flightno;
var airlinename;
var io;
var airlinecode;
$("#update_flight").submit(function(event) { //2
        recordid = $('#RecordID').val();
        hotelid = "<?php echo $_SESSION['_amember_user']['hotelid'];?>";
        flightno = $('#FlightNo').val();
        airlinename = $('#AirlineName').val();
        io = $('#EditIO').val();
        airlinecode = $('#EditAirlineCode').val();
        airlineprefix = $('#EditAirlinePrefix').val();
        $("#EditShowBar").show();
        var status = 1;
        console.log("RECORD ID ", recordid);
        var form = $('form')[1];
        console.log("Form", form);
        var formData = new FormData(form);
        formData.append("RecordID", recordid);

        $(".progress-bar").animate({
        width: "100%"
        }, 2500);

        $.ajax({
        url: "update-flight.php",
        data: formData,
        method: "POST",
        cache: false,
        contentType: false,
        processData: false,
        }).done(function(response) {
        $('#edit_data_Modal_2').modal("hide");
        $('#userTableAllFlights').DataTable().ajax.reload();
        });
});

谁能看出我错在哪里。
