Question

我的应用程序遇到了一些奇怪的问题，我不确定如何追踪，因为它是如此随机。我想知道是否有任何基于下面的堆栈跟踪的想法。

以下是一些快速要点：

问题似乎与View（.cshtml）
它随机出现，它与会话cookie有关，因为如果您从另一台计算机上尝试，那么它没有问题，或者如果您清除缓存，则没有问题
我的GetUserByIdentifier包含在try {} catch {}中，如果我们输入catch {} ..它将返回NULL，它应该重定向到登录屏幕。

这可能是内部导致错误消息的内容吗？这个未处理的异常甚至可能发生在我的login.cshtml页面上，该页面在视图中甚至没有任何代码。

错误消息：
