I need help, I want to exchange information via serialport between Arduino Pro mini with a distance sensor and a local website (e.g. provide information about the end of the session and its beginning) I use Windows 11, node.js with the 'serialport' library (installed locally and globally) , I installed everything a few days ago, because I'm just starting my adventure with it) and of course Arduino with its C++... I've reached the point of connecting via the serial port (now Arduino is on the COM3 port, which I can see in the Arduino IDE and Device Manager), but still I get the error message: "TypeError: SerialPort is not a constructor"...

The code of my app.js file (node.js version: v18.17.1, globally [C:\Users\ja\AppData\Roaming\npm] serialport version is: ` [email protected], and locally also: [email protected]):

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const port = 8080;
app.use(bodyParser.urlencoded({ extended: true }));
app.get('/', (req, res) => {
    res.sendFile(__dirname + '/index.html');
});
app.post('/start-session', (req, res) => {
    const SerialPort = require('serialport');
    const arduinoPort = new SerialPort('COM3', { baudRate: 9600 }); 
    arduinoPort.write('START_SESSION\n', (err) => {
        if (err) {
            console.error('Err Arduino:', err);
        } else {
            console.log('Success Arduino.');
        }
    });
    res.send('Session started.');
});
app.listen(port, () => {
    console.log(`Port ${port}`);
});

My website (lokal) index.html:

    
Hello. Start. :)
    

        Start session
    

Here are the local directories of my project: (images)enter image description here

and in the node_modules directory: enter image description here

Please help me remove the error and connect.
