错误-警告，缺少FIREBASE_CONFIG环境变量.初始化firebase管理将失败

Question

我试图将现有的firestore数据库连接到Dialogflow实现。该函数已成功部署到Google CLoud函数，但我无法将数据添加到我的数据库中。我曾尝试更改节点版本8，但仍然失败。请帮帮我。

索引.js

'use strict';
const admin = require('firebase-admin');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');

admin.initializeApp({
apiKey: "Axxxx",
authDomain: "/xxxxx.firebaseio.com",
databaseURL: "https:/xxxxxx.firebaseio.com",
projectId: "mxxxxx8",
storageBucket: "xxxxx.com",
});
const functions = require('firebase-functions');
const settings = {timestampsInSnapshots: true};
var db = admin.firestore();
admin.firestore().settings({ timestampsInSnapshots: true });

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?`);
}

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

Answer 1

解决方案是将您的Firebase项目计划升级为Blaze plan。然后在Firebase项目下创建一个新的Dialogflow代理。

Answer 2

您的Firebase初始化似乎是错误的。以下是你应该怎么做：

.
.
.
admin.initializeApp({
credential: admin.credential.applicationDefault(),
databaseURL: 'https://<DATABASE_NAME>.firebaseio.com'
});
.
.
.

这应该行得通。

Answer 3

根据文档，应该是这样的

serviceAccount = require('./serviceAccount.json');
const adminConfig = JSON.parse(process.env.FIREBASE_CONFIG);
adminConfig.credential = admin.credential.cert(serviceAccount);
admin.initializeApp(adminConfig);
