Hi, i have a problem which encounter error at staging environment kf-jabatan:2645 Uncaught ReferenceError: KoolReport is not defined

At local environment it works well. But when we copy folder app to staging, getting error Uncaught ReferenceError: KoolReport is not defined

GET https://ddmsstaging.dbkl.gov.my/era/public/era/vendor/koolreport/core/src/clients/core/KoolReport.js net::ERR_ABORTED 404 (Not Found)

KoolReport.widget.init({"js":["\/era\/vendor\/koolreport\/core\/src\/clients\/jquery\/jquery.min.js",    ["\/era\/vendor\/koolreport\/core\/src\/widgets\/koolphp\/table\/table.js"]],"css":    ["\/era\/vendor\/koolreport\/core\/src\/widgets\/koolphp\/table\/table.css"]},function(){
tableData = new KoolReport.koolphp.table('tableData',{"cKeys":["adt_id","fungsi","aktiviti","sub_aktiviti","bil_fail"],"removeDuplicate":[],"paging":{"pageSize":10,"pageIndex":0,"align":"center","itemCount":132,"pageCount":14}});
    });

below is my code using Table:

        Table::create(array(
                    "name"       => "tableData",
                    "dataSource" => $tableData,
                    "columns" => array(
                        "adt_id" => array(
                            "label" => "No"
                        ),
                        "fungsi" => array(
                            "label" => "Fungsi",
                            
                        ),
                        "aktiviti" => array(
                            "label" => "Aktiviti",
                            
                        ),
                        "sub_aktiviti" => array(
                            "label" => "Sub Aktiviti",
                            
                        ),
                        "bil_fail" => array(
                            "label" => "Bilangan Fail",
                            "formatValue" => function ($value, $rowData) use ($listsArray) {
                                $ddms_file_classification_id = $listsArray[$rowData['adt_id'] - 1]['ddms_file_classification_id'];
                                $ddms_file_classification_id1 = $listsArray[$rowData['adt_id'] - 1]['ddms_file_classification_id1'];
                                $ddms_file_classification_id2 = $listsArray[$rowData['adt_id'] - 1]['ddms_file_classification_id2'];
                                $organization_id = $listsArray[$rowData['adt_id'] - 1]['organization_id'];
                                $url = '/report/details-kf-fail/'.$organization_id.'/' . $ddms_file_classification_id . '/' . $ddms_file_classification_id1 . '/' . $ddms_file_classification_id2;
                                return '<a href="' . $url . '">' . $value . '</a>';
                            },
                        )
                    ),
                        "cssClass"=>array(
                        "table"=>"table-bordered table-striped table-hover"
                    ),
                    "paging"=>array(
                        "pageSize"=>10,
                        "pageIndex"=>0,
                        "align"=>"center"
