Failed to load resource: the server responded with a status of 404 (Not Found) on routing - express

Question

I am trying to route in my project. I want that on clicking connect button the rooms page should get rendered. Home page is working fine but as soon I as click connect it shows Cannot GET /rooms/0b2636b5-c254-47f4-ade8-9e6b745a96d1.The code works fine when instead of routing to rooms it is on root url.
I am new to web development and I tried reading other questions on similar problem but couldn't understand.
Server side(Server.js):
const express = require('express');
const app = express();
const server = require('http').Server(app);
const { v4: uuidV4 } = require('uuid');
const io = require('socket.io')(server);
const { ExpressPeerServer } = require('peer');
const peerServer = ExpressPeerServer(server, {
debug: true
});
app.use('/peerjs', peerServer);
app.set('view engine', 'ejs');
app.use(express.static('public'));
app.get('/', (req, res) => {
res.render('home');
})
app.get('/rooms', (req, res) => {
res.redirect(`/rooms/${uuidV4()}`);
})
app.get('/rooms:room', (req, res) => {
res.render('room', { roomId: req.params.room })
})
server.listen(3000);
Client Side(script.js)
const socket = io('/rooms');
const videoGrid = document.getElementById('video-grid');
var peer = new Peer(undefined, {
path: '/peerjs',
host: '/rooms',
port: '3000'
})
Navigation bar on home.ejs
<nav class="nav">
<li class="nav-link">
Connect
</nav>
room.ejs
<script>
const ROOM_ID = "<%=roomId%>"
</script>
<script src="/socket.io/socket.io.js" defer ></script>
<script src="script.js" defer></script>
Structure of file
public
-script.js
views
-home.ejs
-room.ejs

You're really close to it, just 1 mistake in this block:
app.get('/rooms:room', (req, res) => {
res.render('room', { roomId: req.params.room })
})
It should be:
app.get('/rooms/:room', (req, res) => {
res.render('room', { roomId: req.params.room })
})
Express documentation page here in case you need it (section Route parameters).
