TypeError: Cannot read property 'name' of undefined in Nodejs-CodePudding

I am working with Nodejs(Express.js), I am sending form data to "controller" but I am getting folllowing error

TypeError: Cannot read property 'name' of undefined

Here is my controller code,My req.body.name is not working

userController.save = function (req, res, next) {
    var name = req.body.name;
    console.log(name);   
}

Here is my app.js, I am using MVC structure in nodejs

const express = require('express');
const mysql = require('mysql');
const expressValidator = require('express-validator');
const bodyParser = require('body-parser');
const cookieParser = require('cookie-parser');
const session = require('express-session');
const flash = require('connect-flash');
const app = express();
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use('/', routes);
app.set('view engine', 'pug');
app.set('views', path.join(__dirname, 'views'));
app.use(express.static(__dirname   '/public'));
app.use(cookieParser('keyboard cat'));
const PORT = 4000
app.listen(PORT, function (err) {
  if (err) console.log(err);
  console.log("App started on PORT", PORT);
});

Here is my view file code(signup.pug)

 form#myForm.my_form.pt-3(action='', method='POST')
     .form-group
         .row
             .col-md-3
                  label(for='Name') Name
             .col-md-9
                  input#name.form-control(type='text', name='name', placeholder='Enter your name')
     .form-group
         .row.pt-2
              .col-md-12
                  input#submit.btn.btn-dark.form-control(type='submit', name='submit', value='Register')

Although lacking of information, I believe your app.use('/', routes) must be put after the view engine, file path etc.

    const express = require('express');
    const mysql = require('mysql');
    const expressValidator = require('express-validator');
    const bodyParser = require('body-parser');
    const cookieParser = require('cookie-parser');
    const session = require('express-session');
    const flash = require('connect-flash');
    const app = express();
    app.use(bodyParser.urlencoded({ extended: true }));
    app.use(bodyParser.json());

    app.set('view engine', 'pug');
    app.set('views', path.join(__dirname, 'views'));
    app.use(express.static(__dirname   '/public'));
    app.use(cookieParser('keyboard cat'));

    app.use('/', routes);

    const PORT = 4000

    app.listen(PORT, function (err) {
      if (err) console.log(err);
      console.log("App started on PORT", PORT);
    });

You are trying to access the name property on an undefined value, you can avoid this error by using req.body?.name.
