节点JS Steam-Tradeoffer-Manager

Question

I'm working on a SteamTradeBot but I have a problem with getOffer() .

manager.getOffer(trade_id[i],function(offer){...});

My goal is to output the ID and accept the tradeoffer but it doesn't work because offer is set to null.

console.log(offer.id);
                  ^
TypeError: Cannot read property 'id' of null

Is there any way to fix it?

您缺少“错误”回调：

manager.getOffer(trade_id[i],function(err, offer){...});
