无法在 BotFramework 中接收来自 Skype 的附件

Question

在 BotFramework (NodeJS) 上，我试图复制 https://docs.microsoft.com/en-us/bot-framework/nodejs/bot-builder-nodejs-send-receive-attachments 上可用的演示。它实际上运作良好。

代码以防 ms 文章更改：

// Create your bot with a function to receive messages from the user
var bot = new builder.UniversalBot(connector, function (session) {
    var msg = session.message;
    if (msg.attachments && msg.attachments.length > 0) {
     // Echo back attachment
     var attachment = msg.attachments[0];
        session.send({
            text: "You sent:",
            attachments: [
                {
                    contentType: attachment.contentType,
                    contentUrl: attachment.contentUrl,
                    name: attachment.name
                }
            ]
        });
    } else {
        // Echo back users text
        session.send("You said: %s", session.message.text);
    }
});

但是，我面临的问题是，当我从 Skype（正常）拨打电话时，我收到一条错误消息：

2017-12-07T02:16:15.815Z Error: POST to 'https://smba.trafficmanager.net/apis/v3/conversations/<My Conversation>/activities' failed: [400] Bad Request

    at Object.onceWrapper (events.js:313:30)
    at emitNone (events.js:111:20)

有什么想法吗？

[更新：它仅在我创建附件响应时发生。所以我想这就是我遇到问题的地方]

实际上 MS 网站上的代码不是最新的（在某种程度上）。

如果我遵循可见的代码：https://github.com/Microsoft/BotBuilder-Samples/tree/master/Node/core-ReceiveAttachment

例如，我可以接收附件并将其保存在 public 文件夹中的某个位置。完成后，我可以将 "public" URL 作为附件发回，然后就可以使用了。
