监视器内置事件端点消息中的错误：至少为端点创建了一个接收者，纪元为“3”，
Error in monitor built-in event endpoint message: At least one receiver for the endpoint is created with epoch of '3',
我有一个 IoT 中心，我正在尝试监视传入的消息，我在 Visual Studio 2019 年和 VSCODE 都尝试过，右键单击端点内置的 IoTHub 监视器，我收到此错误.

这是错误还是我缺少配置以便能够监控消息？
当您有多个应用程序使用默认的 ($Default) 消费者组从端点读取时，可能会发生此错误。作为最佳实践，您应该为每个消费应用程序创建一个消费者组。当你在 VS2019 或 VS Code 中 right-click 和监控时，它使用默认的消费者组。所以你可以做的是使用 az iot hub monitor-events 命令并使用 -c 标志来指定你创建的消费者组。您可以在 Built-in 端点边栏选项卡的门户中创建一个：
