Я использую Dialogflow InLine Editor и пытаюсь получить результаты от внешнего API, но я получаю следующую ошибку в журналах Firebase:
TypeError: Невозможно прочитать свойство 'then' из неопределенного
на видео (/user_code/index.js:48:9)
в WebhookClient.handleRequest (/user_code/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:303:44)
at exports.dialogflowFirebaseFulfillment.functions.https.onRequest (/user_code/index.js:78:9)
в cloudFunction (/user_code/node_modules/firebase-functions/lib/providers/https.js:57:9)
на /var/tmp/worker/worker.js:725:7
по адресу /var/tmp/worker/worker.js:708:11
в _combinedTickCallback (внутренняя / process / next_tick.js: 73: 7)
at process._tickDomainCallback (internal / process / next_tick.js: 128: 9)
Вот мой код:
'use strict';
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
const request = require('request-promise-native');
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 to my agent!`);
}
function fallback(agent) {
agent.add(`I didn't understand`);
agent.add(`I'm sorry, can you try again?`);
}
function video(agent) {
agent.add(`Sure, You can access to external API`);
const url = "https://reqres.in/api/users?page=2";
return request.get(url)
.then(jsonBody => {
var body = JSON.parse(jsonBody);
agent.add(body.data[0].first_name)
return Promise.resolve(agent);
})
.catch(err => {
console.error('Problem making network call', err);
agent.add('Unable to get result');
return Promise.resolve(agent);
});
}
// 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('video', video);
// intentMap.set('your intent name here', googleAssistantHandler);
agent.handleRequest(intentMap);
});
EDIT :
Я добавил в index.js :
`const request = require('request-promise-native');`
и package.json :
"request-promise-native": "^1.0.5",
"request": "^2.88"
Спасибо за вашу помощь.
