firebase部署错误，运行node.js 16函数应用程序（us-central1）似乎面临问题

Question

我将Express应用程序部署到Firebase功能上。但是在执行功能时会收到错误：创建node.js 16函数应用程序（us-central1）...

这是我的ExpressJS示例下的“ functions”文件夹。我不太确定正在发生的事情

const express = require('express')
const firebasefunctions = require('firebase-functions')
const cors = require('cors')
const dotenv = require('dotenv');
const fs = require('fs');
dotenv.config();


const app = express()
const port = process.env.DB_PORT

app.use(cors())
app.use(express.json())
app.use(express.urlencoded())

const knex = require('knex')({
    client: 'pg',
    connection: {
      host : process.env.DB_HOST,
      port : process.env.DB_DO_PORT,
      user : process.env.DB_USERNAME,
      password : process.env.DB_PASSWORD,
      database : process.env.DB_DO,
      ssl: {
        ca: fs.readFileSync('./ca-certificate.crt').toString()
      }
    }
});

app.get('/data', (req, res) => {
    knex.select().table('tablename')
    .then(response => res.json(response))
    .catch(console.log)
    
})

app.post('/update', (req, res) => {
    
    console.log(req.body)
    req.body.forEach(item => {
        knex('tablename')
        .where('number', '=', item)
        .increment({
            occurence: 1
        })
        .catch(console.log)
    })
    res.json("Success")
})

exports.app = firebasefunctions.https.onRequest(app)

和包装

  "scripts": {
    "serve": "firebase emulators:start --only functions",
    "shell": "firebase functions:shell",

    "logs": "firebase functions:log"
  },
