Node JS post request not working?

Question

Node.js

I'm trying to process a post request. I found a simple code, but for some reason the result is an empty object without the data that I sent

const express = require('express');

const PORT = 8000;

const app = express();
const urlencodedParser = express.urlencoded({extended: false});

app.listen(PORT, () =>{
   console.log(`Server works on port ${PORT}`);
});

app.get('/', (req, res) =>{
    res.send('server works, PORT is ' + PORT);
});

app.post("/pos", urlencodedParser, function (request, response) {
    if(!request.body) return response.sendStatus(400);
    console.log(request.body);
    response.send(`${request.body.userName} - ${request.body.userAge}`);
});

const express = require('express');

const PORT = 8000;

const app = express();
app.use(express.json());
app.use(express.urlencoded({extended: false}))

app.listen(PORT, () =>{
   console.log(`Server works on port ${PORT}`);
});

app.get('/', (req, res) =>{
    res.send('server works, PORT is ' + PORT);
});

app.post("/pos", function (request, response) {
    if(!request.body) return response.sendStatus(400);
    console.log(request.body);
    response.send(`${request.body.userName} - ${request.body.userAge}`);
});
