When I use Promise with dialogflow library in server - get Error












1















I try to execute this code on Firebase Cloud Functions



const functions = require('firebase-functions');
const admin = require('firebase-admin');
const firebase_database = require('./conf/firebase');
const { WebhookClient } = require('dialogflow-fulfillment');

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
function searcheColleagueByName(agent){
var lastname = agent.parameters.lastname;
firebase_database.ref().once('value')
.then(team => {
agent.add("some name " + lastname);
})
.catch(err=>{
agent.add("something wrong");
})
}


and after when i make request to my bot from telegram I get error in firebase console:



Error: No responses defined for platform: null
at V2Agent.sendResponses_ (/srv/node_modules/dialogflow-fulfillment/src/v2-agent.js:243:13)

at <anonymous>
at process._tickDomainCallback (internal/process/next_tick.js:228:7)


What's wrong? why when I use promisse my agent can't give me an answer?

  • You only define a function in the body of the onRequest callback; you don't do or return anything. NB: where would you get the value of agent from? Also, your code has more opening parentheses and braces than closing ones. Please take care of indenting you code properly.

The problem is that, if you're using an async function, then your intent handler must also return a Promise. It isn't enough that you send the reply as part of the then() clause, you must also return the Promise that the then() is part of.



In your case, this looks fairly easy. In the searchColleagueByName() function, you would return then once().then().catch() result, which is a Promise. (Since then() and catch() return a Promise.)



So it might look something like this:



   return firebase_database.ref().once('value')
.then(team => {
agent.add("some name " + lastname);
})
.catch(err=>{
agent.add("something wrong");
})
