botframework - 通过 ReplyToActivityAsync 发送消息时，Bot 框架没有响应

Question

以下部分通常运行良好，但有时它不会响应，该消息来自 Microsoft Teams。我确定端点已收到消息，但无法将消息发送出去。

     public async Task<HttpResponseMessage> Post([FromBody]Activity activity)
{   
  //show typing
  var reply = activity.CreateReply(String.Empty);
  reply.Type = ActivityTypes.Typing;
  ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl));
  await connector.Conversations.ReplyToActivityAsync(reply);
...
}
