offer.addMyItems Error Context

[ahmet]

checks the user's gems and sends a trade offer. but I want the bot to add 1 gems to the trade offer created, but it always gives an error.

I'm trying to do this with the following code trying to add 1 ore from the bot's inventory

offer.addMyItems(item.amount = 1);

I want the bot to add 1 gems to the trade offer. How can I do that?

My Codes; 
 

case "gems":

community.getUserInventory(partner, 753, 6, true, (error, items) => {
	if(error) {
		users.removeReservation(partner, true, removeFunc);
		return callback(error);
	}

	let accepted = files.getConfig().steamGems;
	var botgems = 0;
	var need = price;

	for (var i = 0; i < items.length; i += 1) {
		var item = items[i];
		if (need !== 0) {
			if (accepted.indexOf(item.market_hash_name) >= 0) {

				item.amount = need <= item.amount ? need : item.amount;
				need -= item.amount;
				botgems += item.amount;

			}
		}

		offer.addTheirItem(item);
		offer.addMyItems(item.amount = 1);

		if(botgems == price)
			break;
	}

	if(botgems < price) {
		users.removeReservation(partner, true, removeFunc);

		
			return callback("/quote You do not have enough gems to purchase unique games.");

	}


	if(botgems > price) {
		users.removeReservation(partner, true, removeFunc);

		
			return callback("/quote ❌ An error occurred, please try again later.");
		
	}

	offer.send((error, status) => {
		if(error) {
			users.removeReservation(partner, true, removeFunc);
			return callback(error);
		}

		if(status == "pending") {
			community.acceptConfirmationForObject(files.getConfig().identity, offer.id, error => {
				if(error) {
					users.removeReservation(partner, true, removeFunc);
					return callback(error);
				}

				callback(null, "https://steamcommunity.com/tradeoffer/" + offer.id);
			});
		} else if(status == "sent")
		callback(null, "https://steamcommunity.com/tradeoffer/" + offer.id);
	});
});

break;

You can't do offer.addMyItems(item.amount = 1)

You need to do it like this:

item.amount = 1;
offer.addMyItem(item);
