How to forward a Telegram to another network?

[illia-piskurov]

I am writing a program that will allow you to send telegrams from one network to another and back, it works, but unfortunately not with all types of telegrams. I can't understand why the telegram receiving event doesn't have a data type, so that I can specify it in the justification. Need help!

const KNX = require('knx');

const knxConfig1 = {
    ipAddr: '192.168.31.12',
    ipPort: 3671,
    // physAddr: '1.1.112'
};

const knxConfig2 = {
    ipAddr: '192.168.31.11',
    ipPort: 3671,
    // physAddr: '0.0.253'
};

const knxConnection1 = new KNX.Connection(knxConfig1);
const knxConnection2 = new KNX.Connection(knxConfig2);

knxConnection1.on('connected', () => {
    console.log('Connected to KNX network 1');
});
knxConnection2.on('connected', () => {
    console.log('Connected to KNX network 2');
});

knxConnection1.on('event', (evt, src, dest, value) => {
    debugger;
    knxConnection2.writeRaw(dest, value, (err) => {
        if (err) {
            console.error('Error forwarding telegram to network 2:', err);
        } else {
            console.log(`Forwarded telegram to network 2: ${dest} with value ${value}`);
        }
    });
});

knxConnection2.on('event', (evt, src, dest, value) => {
    knxConnection1.writeRaw(dest, value, (err) => {
        if (err) {
            console.error('Error forwarding telegram to network 1:', err);
        } else {
            console.log(`Forwarded telegram to network 1: ${dest} with value ${value}`);
        }
    });
});

knxConnection1.on('error', (err) => {
    console.error('Error in KNX connection 1:', err);
});

knxConnection2.on('error', (err) => {
    console.error('Error in KNX connection 2:', err);
});
