智慧.ai不解析数据聊天响应

我的机智修改遇到了一些问题。ai的messenger.js在GitHub上。我添加了一些API调用来获得实时天气，但我在获得结果进入机器人的回复(context.forecast)时遇到了麻烦。上下文。天气预报线似乎无法"看到"我的天气数据。

最相关的行是:

context.forecast = 'Todays forecast is: ' + hourlyWeather +' in ' + location;

hourlyWeather有"今天晚上之前有小雨"这样的数据，但是机器人的回复忽略了它。

这里是相关的代码，我希望我只是在错误的地方/订单的东西，因为我是新的节点。谢谢你的帮助。

// Our bot actions
const actions = {
send({sessionId}, {text}, request) {

// Let's retrieve the Facebook user whose session belongs to

if (recipientId) {
  // Yay, we found our recipient!
  // Let's forward our bot response to her.
  // We return a promise to let our bot know when we're done sending

机器人的回复只有"今天的天气预报是:亚特兰大"。
