服务器在找到会话代码时挂起。我正在使用 Sequelize 来存储会话

Question

我有一个已经在运行的应用程序。当我对它的会话部分进行编码时，问题就开始了。当在控制器中找到这行代码时服务器挂起：

req.session.save(() => {
            req.session.loggedIn = true;
         });

用户-routes.js控制器是：

const router = require('express').Router();
console.log(__filename);


router.get('/login', (req, res) => {
    res.render('login');
});

router.post('/verify', (req, res) => {

    try {
        // HERE *********************************************************************
         req.session.save(() => {
            req.session.loggedIn = true;
         });

        const messages = {};
        res.render('dashboard', {messages, loggedIn:req.session.loggedIn},);
    } catch (e) {
    }
});

router.get('/newUser', (req, res) => {
    res.render('newUser');
});

router.post('/saveUser', (req, res) => {
    res.render('dashboard');
});
module.exports = router;

我的 server.js 是：

const root = require('app-root-path')
const express = require('express');
const path = require('path');
const exphbs = require('express-handlebars');

const session = require('express-session');
const SequelizeStore = require('connect-session-sequelize')(session.Store);
const sequelize = require('./config/connection');

const app = express();
const PORT = process.env.PORT || 3000;
const routes = require('./controllers/index');

const configSession = {
    secret: 'this is a secret',
    cookie: {maxAge: 86400,},
    resave: false,
    saveUninitialized: true,
    store: new SequelizeStore({db: sequelize}),
};

app.use(express.json());
app.use(express.static(root + path.sep + 'public'));
app.use(express.urlencoded({extended: true}));
app.use(routes);
app.use(session(configSession));

const hbs = exphbs.create();
app.engine('handlebars', hbs.engine);
app.set('view engine', 'handlebars');

const run = async () => {
    //const sequelizeResult = await sequelize.sync({force: true});
    //console.log("---> sequelizeResult :" + (sequelizeResult));
    await app.listen(PORT, () => {
        console.log('Server listening on port %j', PORT);
    });
}


//RUN 
run();

我正在使用 MySQL。我停止了服务器，删除了数据库表，重新创建并为它们播种。

可能是什么问题？非常感谢您的帮助。

Sequelize 需要在服务器启动时同步 tables（并添加会话 table）。我正在取消注释 sequelize.sync() 被调用的行

const run = async () => {
    const sequelizeResult = await sequelize.sync({force: true});
    //console.log("---> sequelizeResult :" + (sequelizeResult));
    await app.listen(PORT, () => {
        console.log('Server listening on port %j', PORT);
    });
}

问题解决了。
