我正在使用Firebase云函数作为webhook来执行我在谷歌对话流实现上的操作。
我的index.js文件如下
'use strict';
process.env.DEBUG = 'actions-on-google:*';
var requestcall = require('request');
var date = require('date-and-time');
var promise = require('promise');
var AmazonDateParser = require('amazon-date-parser');
var moment = require('moment-timezone');
var accountnum;
var accessToken;
var timePeriod;
var acctnums =[];
// Create functions to handle requests here
const WELCOME_INTENT = 'input.welcome'; // the action name from the Dialogflow intent
const NUMBER_INTENT = 'account_number'; // the action name from the Dialogflow intent
const NUMBER_ARGUMENT = 'number'; // the action name from the Dialogflow intent
const OUT_CONTEXT = 'output_context';
const ACCOUNT_ARG = 'info';
const ACCOUNT_NUM = 'myAccountNum';
const AccountNums = 'AccountNums';
const CURRENCY_SYMBOL = 'CurrencySymbol';
const TIME_ZONE = 'TimeZone';
const STATS_ARG = 'nextStatsData';
const {dialogflow} = require('actions-on-google');
const functions = require('firebase-functions');
const {
SimpleResponse,
BasicCard,
Image,
Suggestions,
Button
} = require('actions-on-google');
const app = dialogflow(
{debug: true,clientId: 'xxxxxxxxxxx.apps.googleusercontent.com'});
app.middleware((conv) => {
});
app.intent('Default Welcome Intent', (conv) => {
console.log('Request headers: ' + JSON.stringify(conv.headers));
console.log('Request body: ' + JSON.stringify(conv.body));
accessToken =conv.body.originalDetectIntentRequest.payload.user.accessToken;
console.log('accessToken: ' + accessToken);
if (accessToken !== null) {
return getaccountDetails(conv).then((entity)=>{
return getMessageFromAccount(entity,conv);
});
}
else{
return conv.close(new SignIn('To get your account details'));
}
});
exports.stats = functions.https.onRequest(app);
我的package.json文件如下

我在谷歌上测试我的操作时出现以下错误
TypeError: Cannot read property 'stack' of undefined
at standard.then.catch (/workspace/node_modules/actions-on-google/dist/framework/express.js:37:32)
at process._tickCallback (internal/process/next_tick.js:68:7)
错误不在我的index.js中。错误在express.js.的谷歌npm模块库上的操作中
我删除了我的节点模块，重新安装并重新生成代码。仍然会出现同样的错误。
请帮我解决这个问题。
如果您在Firebase中使用云函数，我根本不会想到会调用该代码。
我怀疑包括"；express"；依赖项中的包引入了express的外部版本，这混淆了google库上的操作，该库单独定义了express类型。a-o-g库将此库用于那些直接使用express来设置路由的人，如果您使用云函数，则不必使用此库。
我建议删除该包，并确保它不在您的节点模块中。
