I'm using node.js 16 with es6 support enabled and express js,

    import express from 'express'
    import http from 'http'
    
    const app = express()
    app.get('/health', (_req, res, _) => {
    console.log('health check')
    res.sendStatus(200)
    },
    const server = http.createServer(app)
    server.listen(
         8000, '127.0.0.1'
        )

here everything works fine, sending get request on localhost:8000/health return 200

But when I attach socket.io to my HTTP server I get the following error

Server returned nothing (no headers, no data)

I added socket.io like so

import { Server } from 'socket.io'
onst io = new Server()
io.attach(server)

Hints everything was working fine with nodejs 14 that's how my package.json lunch scipt look like

"main": "src/index.js",
"type": "module",
"scripts": {
    "dev": "nodemon --es-module-specifier-resolution=node src/index.js",
},

I get no error when starting the server
