Question

因此，我最近开始着手构建一些Firebase Cloud功能以实现Dialogflow代理。我在Firebase项目中实现了入职功能，但是在尝试与Firestore交互时出现错误。

我已仔细检查以确保我的package.json和本地开发环境相同，但仍然会看到此错误。

感谢您的帮助。如果使用测试Dialogflow控制台或Twilio，似乎没有关系，我会遇到相同的异常。不知何故，诺言有误。 liceRef.get()返回的承诺肯定正在发生，但是我不知道为什么。

'use strict';

const firefunc = require('firebase-functions');
const admin = require('firebase-admin');
const {WebhookClient} = require('dialogflow-fulfillment');
const serviceAccount = require('./service_account.json');

process.env.DEBUG = 'dialogflow:debug'; 
admin.initializeApp({
    credential: admin.credential.cert(serviceAccount)
});

const db = admin.firestore();
const settings = {timestampsInSnapshots: true};
db.settings(settings);

exports.dfWebhook = firefunc.https.onRequest(async (request, response) => {

  const agent = new WebhookClient({ request, response });

  var uid;
  if(agent.requestSource === 'twilio') {
    uid = request.body.originalDetectIntentRequest.payload.data.From;
  } else {
    uid = 'TESTER';
  }
  console.log("USER ID : ", uid);

  async function onboarding(agent) {
    const { name, email, license } = agent.parameters;

    console.log("-----STARTING ONBOARDING FUNCTION-----");

    try {
        const liceRef = db.collection('license').doc(license);
        const getLice = await liceRef.get(); 

        if(!getLice.exists) {
            agent.add("I'm sorry, this license does not exist. blah blah");
        } else {
            if (getLice.data().uid !== uid && getLice.data().uid) {
                agent.add("This license has already been activated for another user etc...");
            } else {
                await liceRef.set({
                    name: name,
                    email: email,
                    uid: uid
                });
                agent.add("blah blah success message");
            }
        }
    } catch (err) {
        console.error(err);
        agent.add("I'm sorry, an error occured and I wasn't able to activate your license. Please try again later or contact support.");
    }
  }

... INTENT HANDLING CODE ETC ...
}

如果没有失败，我在日志语句后会收到此错误：

8:11:13.748 AM - dfWebhook - Unhandled rejection
8:11:13.748 AM - dfWebhook - Error: No responses defined for platform: twilio
    at V2Agent.sendResponses_ (/srv/node_modules/dialogflow-fulfillment/src/v2-agent.js:243:13)
    at WebhookClient.send_ (/srv/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:505:17)
    at promise.then (/srv/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:303:38)
    at <anonymous>
    at process._tickDomainCallback (internal/process/next_tick.js:229:7)

我唯一能想到的是Firebase配置之间一定存在差异，也许Enterprise Google Cloud / Firebase与Personal不同？老实说，我很茫然。我或者丢失了一些显而易见的疯狂的东西，或者还有其他事情正在发生，但是看起来这段代码应该可以工作。

预先感谢您的帮助。
