Как перейти на другую страницу ejs?

Question

[Vit632]

Не получается перейти на другую страницу ejs.

Index.ejs

<h1>Index page</h1>

<a href="/about" >About-1. Описание</a> </br>
<a href="http://localhost:3000/About/" >About-2. Описание</a>

В файл routes.js добавил.

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

routes.js Полный код.

const multer = require('multer');
const rand = require('randomstring');

const filesStorage = multer.diskStorage({
  destination: (req, file, next) => {
    next(null, 'static/uploads/files');
  },
  filename: (req, file, next) => {
    const ext = file.originalname.split('.').pop();
    next(null, rand.generate({
      length: 32,
      charset: 'alphabetic'
    }) + '.' + ext);
  }
});
const filesUpload = new multer({
  storage: filesStorage
});
