Botkit 不发送通用模板（附件）facebook messenger

Question

我正在尝试用这条消息回复用户：

  bot.reply(message, {
                    "attachment":
                    {
                        "type": "template",
                        "payload": {
                            "template_type": "generic",
                            "sharable": true,
                            "elements": [
                                {
                                    "title": "MY title of bd",
                                    "image_url": "https://storage.googleapis.com/ssfkj.com/undefined",
                                    "subtitle": "undefined/undefinedundefinedn(undefined)",
                                    "default_action": { "type": "web_url", "url": "https://ssfkj.com/profile", "messenger_extensions": true, "webview_height_ratio": "tall", "fallback_url": "https://ssfkj.com/profile" }
                                    , "buttons": [{ "type": "payload", "payload": "DEL__PA_undefined", "title": "View more" }
                                    ]
                                }]
                        }
                    }
                });

但是机器人没有发送任何东西。我的代码有什么问题？

我的问题是在这个层面上：

"buttons": [{ "type": "payload", "payload": "DEL__PA_undefined", "title": "View more" }]

type property

应该有值

postback

不是
