Try with this,
you are tring to do something inrelevent that is not supported.
const request = require('request');
const config = require('./config');
const {weatherAsQuickReply,getWeather} = require('./temp2');
const callSendAPI = (messageData) => {
......
}
const sendMessage = (event) => {
let sender = event.sender.id;
let text = event.message.text;
let apiai = apiaiApp.textRequest(text, {
sessionId: 'minaaaaa213'
});
apiai.on('response', (response) => {
...
});
}
module.exports = {
callSendAPI,
sendMessage
}
Second File
const request = require('request');
const config = require('./config');
const {callSendAPI,sendMessage} = require('./temp');
const weatherAsQuickReply = (messageData) => {
...
callSendAPI(sendQuickReply);
}
const getWeather = (result, messageData) => {
// Direct call Function like this
weatherAsQuickReply(messageData);
}
module.exports = {
weatherAsQuickReply,
getWeather
}
