Some JSON objects is undefined - json

Question

So I'm working a bit with nodeJS and Steam API to try and make a trade bot
I need to know what items was recieved, but when I do I get
undefined
Here's the JSON:
{

}
I can easily get partner, id, message, state, isOurOffer and all the time things, but when I try to get itemsToRecieve, it just throws undefined
The JSON is gathered through an event and the above is the exact JSON that I recieved
This is the event:
manager.on('sentOfferChanged', function(offer, oldState) {
var state = offer.state;
if(state == 3) {
console.log("Offer " + offer.id + " was accepted");
console.log("[Offer #" + offer.id + "] The following items was recieved: ");
console.log(offer.itemsToReceive);
}
});
Why would it do that for only one of the objects?

Answer 1

Maybe you can use a for to log each item of itemToReceive.
Something like this:
manager.on('sentOfferChanged', function(offer, oldState) {
var state = offer.state;
if(state == 3) {
console.log("Offer " + offer.id + " was accepted");
console.log("[Offer #" + offer.id + "] The following items was recieved: ");
for(var i in itemstoReceive)
{
var name = itemsToReceive[i].name;
console.log(name);
}}
});
