It usually helps to print out values of variables when debugging. In this case, I suspect one of appid, contextid, or assetid is undefined or not the value you are expecting.

If you want to do anything that limited users can't do, then you need to spend $5 on Steam.

"Currencies" are a weird thing that I don't think anyone except Spiral Knights uses.

You must use assetid. You can't use classid or instanceid when sending a trade offer.

Never throw away an error. Check err before you try to do anything. Also, I sincerely hope that isn't your actual secret.

https://github.com/DoctorMcKay/node-steamcommunity/wiki/SteamCommunity#sessionexpired When your session expires, just log in again. If you logged in via steam-user, call webLogOn again. If you logged in via steamcommunity, call login again.

Your session has expired. Log in again.

Use the WebAPI for that.

There is no way to do this. You can parse the CS:GO item schema that ships with the game, but I don't believe it'll get you what you want.

Log in again.

You should try again.

Use node-steamcommunity for that: https://github.com/DoctorMcKay/node-steamcommunity/wiki/CSteamGroup#joincallback

Right. If you were using node-steam-user then just using offer.partner would work, but since you're using node-steam you need to convert it to a string.

Run npm update and it should go away.

I assume friends is not node-steam-user?

Once you're logged in, you need to use the same IP for all your requests.

Yes, the exterior is available in both the tags and the market_name.

offer.addMyItem(inventory) inventory here is an array of items. If you want to grab the first item from your inventory then use inventory[0].

You need to confirm the offer. https://dev.doctormckay.com/topic/289-trading-and-escrow-mobile-trade-confirmations/

It does not.

That looks right to me. Are you friends with the people you're requesting data for?

client.setPersona(SteamUser.EPersonaState.Offline); That says offline to me.

That shouldn't be possible. All I can figure is that you aren't grabbing the same item, or else it's already left your inventory.

I'm not sure I'm following. An offer is accepted, you call getReceivedItems and save its ID. Then you load your inventory and the ID of the item in your inventory is different?
