Error: No responses defined for platform: DIALOGFLOW_CONSOLE

[DMani009]

Hi All,

I am trying to read data from an API in Dialogflow. Below is the code but I am getting the following error and it looks like I have defined my responses in agent.add but still getting the following error. I am not a java expert but trying to learn and maybe I am doing some syntax error. I am not sure but I would appreciate your time and help. Following are errors i am getting:

My code is below:
// See https://github.com/dialogflow/dialogflow-fulfillment-nodejs
// for Dialogflow fulfillment library docs, samples, and to report issues
'use strict';

const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const axios = require('axios');

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

function getSpreadsheetData(){
return axios.get('https://sheetdb.io/api/v1/y79vpk8pj29cv');
}

function welcome(agent) {
const city =agent.parameters.city;
return getSpreadsheetData().then(res => {
res.data.map(person => {
if(person.City === city)
agent.add(Here are the details for ${"city"}.CollectionC: ${person.CollectionC}, Address: ${person.Address}, Phone: ${person.Phone});
});
});
}

function fallback(agent) {
agent.add(I didn't understand);
agent.add(I'm sorry, can you try again?);
}

// // Uncomment and edit to make your own intent handler
// // uncomment intentMap.set('your intent name here', yourFunctionHandler);
// // below to get this function to be run when a Dialogflow intent is matched
// function yourFunctionHandler(agent) {
// agent.add(This message is from Dialogflow's Cloud Functions for Firebase editor!);
// agent.add(new Card({
// title: Title: this is a card title,
// imageUrl: 'https://developers.google.com/actions/images/badges/XPM_BADGING_GoogleAssistant_VER.png',

// buttonUrl: 'https://assistant.google.com/'
// })
// );
// agent.add(new Suggestion(Quick Reply));
// agent.add(new Suggestion(Suggestion));
// agent.setContext({ name: 'weather', lifespan: 2, parameters: { city: 'Rome' }});
// }

// // Uncomment and edit to make your own Google Assistant intent handler

// intentMap.set('your intent name here', yourFunctionHandler);
// intentMap.set('your intent name here', googleAssistantHandler);
agent.handleRequest(intentMap);
});

In my case I had to return an agent.
if(person.City === city)
return agent.add(Here are the details for ${"city"}.CollectionC: ${person.CollectionC}, Address: ${person.Address}, Phone: ${person.Phone});

Also make sure your Google Development account is activated with billing information. In trial mode remote call's are not allowed.
You can check the result in the Diagnostic info.

"webhookStatus": {
"message": "Webhook execution successful"
}

If an error is shown chances are your account is not acitvated. This took me a couple of days myself, billing information was defined but account was still in trial model, once activated the error No responses defined for platform: DIALOGFLOW_CONSOLE was gone!

I was struggling with this error for hours, only to find out I needed to change these 2 little things:

• in package.json, change the version of "dialogflow-fulfillment" to "0.6.1" (instead of 0.5.0)
• make sure your intent has at least 1 default response in the bottom section of the intent configuration screen (Dialogflow ES)

Thanks A LOT!

Hi guys! I'm new to nodejs and dialogflow and am getting this exact same error when trying to integrate my GPT-J from banana with Dialogflow, below is my codes and I would really appreciate any help 🙏🙏

const express = require("express");
require("actions-on-google")
require('dotenv').config();
const axios = require('axios');
const { WebhookClient } = require("dialogflow-fulfillment");
const app = express();
const fetch = require('node-fetch');
const banana = require('@banana-dev/banana-dev');

app.get('/', (req,res) => {
    res.send('Welcome to Dialogflow-GPTJ2 Application!!');
  })

app.post("/dialogflow", express.json(), (req, res) => {
const agent = new WebhookClient({ request: req, response: res });
let intentMap = new Map();
intentMap.set("Default Welcome Intent", welcome);
intentMap.set("Default Fallback Intent", defaultFallback);
agent.handleRequest(intentMap);

function welcome(agent) {
    agent.add('Hi, I am Debra! I am your virtual personal assistant from Orient Telecoms. How are you doing today?');
}

async function defaultFallback(agent) {
    let query = agent.query;
    console.log('querytext: ', query)
    var modelKey = "gptj"

    const modelParameters = {
        "text":query,
        "length":50,
        "temperature":0.9,
        "batchSize": 1
    }

    try {
        let run = async (modelParameters) => {
            var botResponse = await banana.run(process.env.apiKey, modelKey, modelParameters)
            
            console.log('botResponse: ', botResponse)
            agent.add(botResponse)
        }
    } catch (err) {
        console.log('This is error:', err);
        agent.add('Sorry. Something went wrong. Can you say that again?');
    }
}
});

const port = 3000;
app.listen(port, () => console.log(`App listening on port ${port}!`))

When I tried to use Dialogflow to update google Sheets using Axios. I met the same error, but an expert helps me fix the issue via the following code:
`'use strict';

const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const axios = require('axios');
// const qs = require('qs');

process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements

exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));

function welcome(agent) {
agent.add(welcome);
}

function fallback(agent) {
agent.add(I didn't understand);
agent.add(I'm sorry, can you try again?);
}

function bookkeepingHandler(agent) {
axios.post(https://sheetdb.io/api/v1/htvjf0t8az3f8?sheet=Entries, {"data": {
"EntryType":agent.parameters.entrytype,
"Date":agent.parameters.date,
"Amount":agent.parameters.amount
}
});
agent.add(Thank you! Check the google sheet for the data recorded.);
}
//data，{header: {'x-api-key': 'eRjwrg6ya88d1i@z#91cb01rz%u$6cxU5FOf#3LG#P%8$#JZwlj9aawgHhabpYGT'}}
// Run the proper function handler based on the matched Dialogflow intent name
let intentMap = new Map();
intentMap.set('Default Welcome Intent', welcome);
intentMap.set('Default Fallback Intent', fallback);
intentMap.set('bookkeepEntry', bookkeepingHandler);
//intentMap.set('bookNow', bookkeepingHandler);
// intentMap.set('your intent name here', googleAssistantHandler);
agent.handleRequest(intentMap);
});`

Pay attention to the code here (`` symbol is very important):
axios.post(https://sheetdb.io/api/v1/htvjf0t8az3f8?sheet=Entries, {"data": {
"EntryType":agent.parameters.entrytype,
"Date":agent.parameters.date,
"Amount":agent.parameters.amount
}
});
