如何解决由于不活动，重定向后 URL 抛出 500 错误
我有一个 .net Core 3.1 应用程序，在 20 分钟没有活动后，我重定向到一个已注销的页面。在那个页面上，我有一个指向主站点的 URL 的链接，用户应该能够点击它返回到主登录页面。但是，单击该链接会显示 500 错误而不是登录页面。我什至无法输入网址。重新访问该站点的唯一方法是关闭并重新打开浏览器。
我猜这与会话有关，但我不确定如何更正。这是在我的 statup.cs
services.AddSession(options => {
options.IdleTimeout = TimeSpan.FromMinutes(20);
options.Cookie.SecurePolicy = CookieSecurePolicy.Always;
});
我正在使用 bootstrap.session.timeout
这里是js文件：
(function($) {
/*jshint multistr: true */

keepAliveInterval: 5000,keepAlive: true,ignoreUserActivity: false,onStart: false,onWarn: false,onRedir: false,countdownMessage: 'Redirecting in:',//countdownMessage: false,countdownBar: true,countdownSmart: true
};
var opt = defaults,timer,countdown = {};
// Extend user-set options over defaults
if (options) {
opt = $.extend(defaults,options);
}
// Some error handling if options are miss-configured
if (opt.warnAfter >= opt.redirAfter) {
console.error('Bootstrap-session-timeout plugin is miss-configured. Option "redirAfter" must be equal or greater than "warnAfter".');
return false;
}
// Unless user set his own callback function,prepare bootstrap modal elements and events
if (typeof opt.onWarn !== 'function') {
// If opt.countdownMessage is defined add a coundown timer message to the modal dialog
