jQuery突然:未捕获类型错误:非法调用

以下代码正在工作，但由于某种原因，第二天它一直在抛出：未捕获类型错误：非法调用

我似乎不知道它会在哪里破产。

function createFile() {
        var selected_retailer_uuid = $("#search_store_select").select2("val");
        var selected_video_uuid = $("#active_media_videos").select2("val");
        var StartDate = $("#add_new_row_start_date").val();
        var EndDate = $("#add_new_row_end_date").val();
        var number_of_screens = $("#num_of_screens").select2("val");
        var priority_upload_selected = $('#add_new_row_priority_upload').select2("val");
        var get_start_times = getFirstPlayedBox();
        var get_end_times = getSecondPlayedBox();
        var selected_weekday_val = $("#weekdays_selected_input").select2("val");
        $.ajax({
            type: 'POST',
            url: './inc/uploadManagerScript.php?argument=createVideoFile',
            data: {
                store_uuid: selected_retailer_uuid,
                media_uuid: selected_video_uuid,
                start_date: StartDate,
                end_date: EndDate,
                number_of_screens: number_of_screens,
                video_priority_upload: priority_upload_selected,
                start_time: get_start_times,
                end_time: get_end_times,
                weekday: selected_weekday_val
            },
            dataType: 'json'
            })
            .done(function(data) {
                if(data){
                    $(".upload_manager_confirm_save .upload_manager_confirm_text").html("File copied to process folder");
                    $(".upload_manager_confirm_save").fadeIn(300).delay(1000).fadeOut(500);
                }
            });
    }

此代码获取get_start_times，这与get_start_times相同。

 var start_time = [];
    function getFirstPlayedBox(){
        var start_time = [];
        $.each($('[class^=created_firstBox]'), function (i, item){
            start_time.push($(this).val());
        });
        for(i=0;i<start_time.length;i++){
            start_time[i];
        }
        return start_time;
    }

我正在为一个小团队工作。我不知道是谁改变了什么，但它坏了。有什么想法吗？
