Bot Framework Composer开发的Bot部署Azure Web App后Web Chat无响应排查

问题概述 #

我用Bot Framework Composer创建了一个Bot，通过「Create resources」和「Import resources」部署时遇到诸多问题，最终通过GitHub将其部署到Azure Web App。但现在在关联的Azure Bot门户「Test Web Chat」中测试时，Bot没有任何响应——此前在Bot Framework Composer内运行完全正常。

该Bot的功能是接收用户消息并发送到我的外部API，再将API回复返回给用户，但目前无法正常工作。查看Web App的Log Stream时发现：每次重启都会创建、启动然后停止容器，发送消息后没有任何日志记录，我无法调试Bot是否读取到消息，也不确定它是否调用了在Bot Framework Composer中关联的API。
