I have intigrated the sslcommerz payment gateway but when I am completing my transaction successfully, instead of redirecting me in the dashboard page, it is throwing the following error: UnhandledPromiseRejectionWarning: TypeError: Cannot read property '_id' of undefined Code for payment gateway is:
const express = require( 'express' );
const router = express.Router();

router.post( '/charge', isLoggedIn, async ( req, res ) =>
{
const id = crypto.randomBytes( 16 ).toString( "hex" );
const { amount } = req.body;
console.log( id + " " + amount );

Code of app.js:
//App creation
const express = require("express");
const app = express();
//port setup
require('dotenv').config();
const port = process.env.PORT || 8080;
//body parser configutation
const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({extended: true}));
//morgan configuration
const morgan = require('morgan');
app.use(morgan('dev'));
const cookieParser = require('cookie-parser')
app.use(cookieParser(process.env.SESSION_SECRET));
app.use(require('express-session')({
secret: process.env.SESSION_SECRET,
cookie :
{
expires: false
},
resave: true,
saveUninitialized: true
}));
//passport configuration
const passport = require('passport');
app.use(passport.initialize());
app.use(passport.session());
const localStrategy = require('passport-local');
const User = require('./models/user');
passport.use(new localStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
//router configuration
const userRoutes = require('./routes/user');
app.use('/user',userRoutes);
const loanRoutes = require('./routes/loan');
app.use('/loan',loanRoutes);
const adminRoutes = require('./routes/admin');
app.use('/admin',adminRoutes);
const paymentRoutes = require('./routes/payment');
app.use('/payment',paymentRoutes);
//database connection
const mongoose = require('mongoose');
mongoose.connect("mongodb+srv://sifat:12345@cluster0.xtknfmw.mongodb.net/test", function(err) {
if (err) {
console.log("Database Not Connected", err);
} else {
console.log("Database Connected")
}
});
mongoose.set('useFindAndModify', false);
//Other usage for application
app.use(express.static("public"));
app.use((req,res,next)=>{
res.locals.currentUser = req.user;
next();
});
app.set('view engine','ejs');
//Home page
app.get('/',(req,res)=>{res.render('home');})
//Server Start
app.listen(port, () => {console.log(`Server is running on port ${port}`);});
I think the problem is in the express session that I am using. I have set the cookie parser in my code but its still throwing the error
