NodeJS代码在本地运行,但在Azure应用服务中不运行

我正在尝试使用简单的API登录在Azure中创建一个应用服务,该登录在本地运行良好,但在Azure中失败。

const express= require("express");
const app = express();
const bodyparser = require('body-parser')
const mysql = require("./DbConnect").connection;
const port = process.env.port || process.env.PORT || 3001;

app.use(bodyparser.urlencoded({extended: false}))
app.use(bodyparser.json())

app.post("/login", (req, res) => {

    let user  = req.param('user',null);
    let password = req.param('password',null);
    
    let qry = "select * from user where username ='" + user + "' AND password='" + password + "'";
    
    mysql.query(qry, (err, results) => {

        if (err)
            res.status(500).send("DB is not available!")
        else {
            if (results.length > 0) {
                res.status(200).send(results);
            }else{
                res.status(404).send("Email Or Password InCorrect")
            }
        }
    });

});

当我使用postman在本地运行这个程序时,我立即收到“DB is not available!”错误消息。但是当我在Azure应用服务中运行这个程序时,我收到“:(Application Error)”。请注意,构建和部署是成功的。我做错了什么?

但是我的package.json没有任何demon。

{
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon App.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.18.2",
    "mysql": "^2.18.1",
    "nodemon": "^2.0.20"
  }
}

终于用Docker解决了这个问题!
Package.json应该具有

"main": "app.js",
  "scripts": {
    "start": "node app.js"
  },
