Azure functions 在application insights中获取异常消息

我有一个C#azure函数，它正在抛出一个异常：

[FunctionName（“Function1”）]
公共静态异步任务运行(
[HttpTrigger（AuthorizationLevel.Function，“get”，“post”，Route=null）]HttpRequest请求，
ILogger日志）
{
抛出新异常（“有用消息”）；
}

异常被运行时捕获并重新抛出。在application insight中，在执行function:Function1和调用堆栈时，这将与消息

异常一起记录。我在任何地方都找不到“有用的信息”

在Application Insights中，我看到此属性和非属性都有“有用消息”文本：

callstack显示错误的位置：
