制表器网格ajaxError函数未调用

如何解决制表器网格ajaxError函数未调用

我在角度页面中使用制表符网格。我正在使用ajax调用将数据加载到网格中，但无法处理从网络调用引发的错误。我尝试使用ajaxError，但是在抛出500错误时永远不会调用该函数。我在下面提供了我的代码

this.exTable = new Tabulator("#test-table",{
  height: 450,layout: "fitColumns",placeholder: "No Records Found",ajaxLoader: false,columns: [
    { title: "Order",field: "Order",width: 80 }
  ],movableColumns: true,pagination: "remote",ajaxURL: url,ajaxParams: { order: orderId },ajaxRequesting:function(url,params){
    scope._ngxSpinner.show();
  },ajaxConfig: {
    dataType: 'json',credentials: 'include',headers: {
      'Accept': 'application/json',//tell the server we need JSON back
      'X-Requested-With': 'XMLHttpRequest',//fix to help some frameworks respond correctly to request
      'Content-Type': 'application/json; charset=utf-8',//set specific content type        
      'Authorization': 'Basic ' + btoa(userName + ':' + password),},ajaxResponse: function (url,params,response) {
    let tempObj = {};
    if (response.isSuccess == true) {
      this.gridData = response.data.rows;
      tempObj['data'] = this.gridData;
    } else {
      scope.logger.logError(response.error);
    }
    scope._ngxSpinner.hide();
    return tempObj;
  },ajaxError:function(xhr,textStatus,errorThrown){
    scope._ngxSpinner.hide();
    console.log('xhr'+JSON.stringify(xhr)+'textStatus'+textStatus+'errorThrown'+errorThrown)
  },paginationSize: 10,paginationSizeSelector: [10,20,30]
});
