Javascript 当我的js文件中有异步方法时，ASP.NET MVC绑定失败

我们开始移动遗留的js脚本以符合最新的规范，并将一些js方法更改为async。比如说

const persistMode = async (serverUrl, id, mode) => {
   const data = JSON.stringify({id: id, mode: mode});
   const ajaxProperties = {
       type: "POST",
       url: serverUrl,
       data: data,
       dataType: "json",
       contentType: "application/json"
   };
   return await $.ajax(ajaxProperties);
};

现在我定义了一个bundle，并在cshtml文件中引用它，如下所示

@Scripts.Render("~/bundles/fc")

现在，当视图加载时，我得到以下错误

    System.NullReferenceException: Object reference not set to an instance of an object.

知道这里出了什么问题吗。而且，如果我从上述方法中删除async/await，绑定就会起作用。

尝试使用以下算法：

function onSuccess(result) {

       ....succes code
    };

function onError(xhr, exceptio) {

       .... error code
    };

function getData( serverUrl, id, mode ) {

       var data={id: id, mode: mode}
        $.ajax({
            async: true,
            url: serverUrl,
            type: "POST",
            cache: false,
            data: data,
            dataType: "json",
              contentType: "application/json"
            success: function (result) {

                onSuccess(result);
               return true;
            },
            error: function (xhr, exception) {
                onError(xhr, exception);
                return false;
            }
        });
    };
