Ajax没有调用webmethod

Question

Ajax方法没有调用web方法。当我在浏览器中检查它显示错误数据=对象{消息：“身份验证失败。”，StackTrace：null，ExceptionType：“System.InvalidOperationException”}如何解决，我也尝试更改Route.config设置.AutoRedirectMode = RedirectMode.Permanent;到settings.AutoRedirectMode = RedirectMode.Off;但它没有解决。

 $(document).on("click", ".editButton", function () {
                    $("#myModal").focus();
                    var id = $(this).attr("data-id");
                    debugger;
                    console.log(id);
                    $("#btnUpdate").attr("edit-id", id);
                    $.ajax({
                        type: "Post",
                        contentType: "application/json; charset=utf-8",
                        url: '<%= ResolveUrl("CustTableView.aspx/EditData") %>',
