在 Teams 机器人中发送输入 activity 失败 - 网关错误

Question

我非常有信心这是由于 Teams 工程师又搞砸了，但可能值得一试...

使用 Microsoft.Bot.Builder 4.8.0

我其实是个很简单的问题。从 Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)、
调用时以下代码：

await turnContext.SendActivityAsync(typing).ConfigureAwait(false);

导致以下异常：

Operation returned an invalid status code 'BadGateway'

具有以下堆栈跟踪：

回复短信没问题。

哦，以防万一，如果您想知道我是否尝试使用 ShowTypingMiddleware 来显示 "typing" 指标，当然，也尝试过，但指标从未显示。我通过将 Use(new ShowTypingMiddleware(1000)); 添加到我的 BotFrameworkHttpAdapter 构造函数来做到这一点，该构造函数作为单例注册到 DI 容器。就是这样，它什么都不做。

查看 Microsoft Teams：开发人员博客； API outage: Bots posting typing indicators may receive 502s.

As a part of our commitment to customers and Microsoft cloud services continuity during these unprecedented times, we’re making temporary adjustments to select capabilities within Microsoft 365. One of those adjustments is that we are temporarily scaling back typing indicators support in Teams. As a result bots posting typing indicators to users in the Europe region using any of the following values for ServiceUrl may receive errors and users may not see the typing indicators sent by bots.

目前post上面的指导是：

As a bot developer, you may either modify your code to not use typing indicators for now, or ignore the errors encountered while sending typing indicators.
