Node.js TurnContext.updateActivity（）引发错误：不是已知的活动id

我正在尝试更新由bot发送给用户的消息。用例是在后台进程中使用状态更改不断更新卡。我正在使用v4的bot框架和nodejs来实现bot

我正在尝试使用adapter.continueConversation（）传递状态更改，如代码段所示

server.post('/api/notify', (req, res) => {
    const conversationReference: ConversationReference = conversationReferences[req.query.refId]; //stored conversation references   
    adapter.continueConversation(conversationReference, async (context) => {
        //stored activities
        const activity: Partial<Activity> = activityMap[req.query.i];
        let updatedActivity: Partial<Activity> = {};
        updatedActivity.id = req.query.id || activity.id;
        updatedActivity.text = 'Finally updated';
        updatedActivity.serviceUrl = activity.serviceUrl;
        updatedActivity.conversation = activity.conversation;
        console.log(updatedActivity);
        await context.updateActivity(updatedActivity); //Error
    });
    res.send(200);
    res.end();
});

我认为该活动将使用文本“Finally updated”进行更新，但我得到的却是“Error:not a known activity id”。id为“8de84b20-9f4d-11e9-be24-034531d2d092”，与已发送的活动id相匹配。

您试图在哪个频道（即网络聊天、Facebook、MS团队等）上实现此功能？最终目的是为MS团队实现此功能，但在使用emulator测试此代码时会出现上述错误。我发现一个线程说emulator不支持更新和删除活动，但如果是这样的话，则该消息会产生误导。您试图在哪个渠道（即网络聊天、Facebook、MS团队等）上实现此功能？最终目标是为MS团队实现此功能，但是，当使用emulator测试此代码时，会出现上述错误。我发现一个线程说emulator不存在更新和删除活动支持，但如果是这样的话，这个消息是误导性的。
