I deleted useless code

function sendSomeItem() {
	console.log('function started')
    const partner = '76561198989375284';
    const appid = 730;
    const contextid = 2;
    const offer = manager.createOffer(partner);

    offer.addTheirItem({
        'assetid': 18697938160,
        'appid': appid,
        'contextid': contextid
    });
    offer.setMessage('Test offer');
    offer.send((err, status) => {
        if (err) {
            console.log(err);
        } else {
            console.log(`Sent offer. Status: ${status}.`);
        }
    });
}

Now i get function started and error that i must have steam guard for at least 15 days. So i think this is working  Thank you so much for that fast answers <3 

I edited the code so you can see my partner variable. I thought that i must load somebody's inventory to add their items and the partner is his profile id.

I want to send trade offer where i add only somebody's item.

function sendSomeItem() {

    const partner = '76561198989375284';
    const appid = 730;
    const contextid = 2;
    const offer = manager.createOffer(partner);

    manager.loadInventory(appid, contextid, true, (err, myInv) => {

        if (err) {
            console.log(err);
        } else {
            manager.loadUserInventory(partner, appid, contextid, true, (err, theirInv) => {
                if (err) {
                    console.log(err);
                } else {
                    offer.addTheirItem({
                        'assetid': 18697938160,
                        'appid': appid,
                        'contextid': contextid
                    });
                    offer.setMessage('Test offer');
                    offer.send((err, status) => {
                        if (err) {
                            console.log(err);
                        } else {
                            console.log(`Sent offer. Status: ${status}.`);
                        }
                    });
                }
            });
        }
    });
}

I use this simple code to test my code. It logging me, and after delay, trying to send a trade offer. 

client.logOn(logInOptions);
client.on('loggedOn', () => {
	console.log('logged on');
	setTimeout(sendSomeItem, 5000);
});

But i get this error:

I don't know what is wrong. Logging works fine.

Hey, i would like to make a simple bot that decline all offers. I already installed node.js and used npm command to install code. But i don't know what to do know. Any helps? I tried following instructions but i can't find anything like step by step setup. I know that my message may be a bit annoying but i will really  appreciate any help.
