How do you know that specific items map to a different asset ID, if the asset ID reported by the receipt exists?

Show your code. I suspect you aren't passing a function as the first argument to offer.send().

There is no need to call community.setCookies since you're using manager.setCookies and you passed the SteamCommunity instance to the TradeOfferManager constructor. Can you add some output to the webSession event to make sure that's getting emitted properly?

https://github.com/DoctorMcKay/node-steam-tradeoffer-manager/blob/master/examples/storehouse-steam.js You should be able to relatively easily modify this example to only accept offers where you don't give any items (e.g. offer.itemsToGive == 0)

steam-tradeoffer-manager never had anything to do with this, so there isn't anything to update.

See cancelTime here: https://github.com/DoctorMcKay/node-steam-tradeoffer-manager/wiki/TradeOfferManager#constructoroptions

I suggest you check again.

All the information I have is that it doesn't work. http://apistatus.steam.pm

A pretty easy way to invalidate your session: community.setCookies(["steamLogin=invalid", "steamLoginSecure=invalid"]);

You seem to be under the mistaken impression that any of us work for Valve.

42 = NoMatch Did you perhaps set the apiKey property manually?

Yes.

Can you console.log(offer.partner)?

Clearly the item ID doesn't exist in the inventory.

Your account is most likely limited. You can't use this module with limited Steam accounts.

I need to see your code.

Looks like one of the items you're trying to add is undefined. Perhaps someone's inventory is empty?

The first argument is me.

I don't work for Valve.

If you have the mobile authenticator enabled, then logging in from a new device won't ever result in a trade cooldown. Otherwise, it will, but only for that device, meaning you can test it safely without any risk.
