Passing offer.addMyItem or offer.addTheirItem as argument error

Recommended Posts

const manager   = new TradeOfferManager ({
  steam: client,
  community: community,
  language: 'en'

function make_trade(partner, sellingit, item){ // {"name":"","amount":0,"price":{"ref":0,"keys":0}}
    const offer = manager.createOffer(partner);

    function test(sellinv){
      var sell_added = 0
      for(var c=0; c<=sellinv.length-1; c++){
        if(sellinv[c].market_name == item.name && sell_added < item.amount && sellinv[c].tradable == true){
      offer.send((err, status) => {
        if (err) {
        } else {
          console.log(`Sent offer. Status: ${status}.`);
          client.chatMessage(partner, `The offer is ${status}`)

  	var buyer_add = offer.addTheirItem
    manager.getUserInventoryContents(partner, appid, contextid, true, (err, inv) => {})

    var seller_add = offer.addMyItem
    manager.getInventoryContents(appid, contextid, true, (err, inv) =>{test(inv)})

I dont know if i am doing it right or its just tradeoffer manager, when changed seller_add() at test function to offer.addMyItem Works fine
