c# - Microsoft Bot v4 Skill Bot 响应 500（内部服务器）
问题描述
我正在使用带有 Master Bot 和 Child Bot 的 Microsoft Bot framework v4（CoreBot 模板）。
我已经修改了示例代码，并且能够在 Child bot 和 Master Bot 之间建立连接。准确地说，来自 Master bot 的请求成功地击中了 Child bot。但是，主机器人收到 500 内部服务器错误作为子机器人的响应。但是 Child 机器人可以独立工作。
这是我在 Master Bot 收到的错误消息：
An unhandled exception occurred while processing the request.

这种问题的可能原因是什么？我不明白 Child Bot 出现此问题的根本原因，因为它独立工作而没有任何错误。
如果您可以观察代码中是否有问题，请提供帮助。
谢谢。
