正在注册应用程序。UseExceptionHandler导致中间件未接收到异常c#net7.0

我有一个简单的项目,我正试图将其配置为向外部错误报告服务报告异常。

在抛出异常时,我希望蜜獾中间件调用wait client.NotifyAsync(exception) 。这在我注册应用程序之前一直有效。UseExceptionHandler(“/error”)。

我可以看到调用到达中间件Invoke方法,但是当在等待的上下文中抛出expcption时,它不会返回到Invoke方法。

请有人解释为什么会出现这种情况,以及我能做些什么来确保HoneybadgerMiddleware在expection时首先被调用,报告expection,然后重新抛出异常,以便UseExceptionHandler控制器接收它。
