new_assetid from getExchangeDetails is undefined

[G35]

Hi, 

I call getExchangeDetails immediatly after get event from receivedOfferChanged. This used to work fine, but today I started getting undefined new_assetid. Should I do something different to reliably get new_assetid? 

 

Thanks.

seems like steam changed something. tried adding delay before calling getExchangeDetails, but didn't change anything, still undefined

Running node-steam-tradeoffer-manager. Trades are completing normally (state 3, items physically transfer between inventories), but new_assetid is missing from every endpoint I'd normally use to retrieve it:

1. IEconService/GetTradeStatus — new_assetid field absent from response
2. IEconService/GetTradeOffer — same
3. IEconService/GetTradeHistory — same
4. /trade/{tradeid}/receipt/ — HTML returns 200 with "1 new item acquired" text and the standard layout, but the var oItem; declaration is empty (no oItem = {...} block, no BuildHover('item0', ...) call)

Tested on CS2 (appid 730). 

Inventory endpoints (/inventory/{steamID}/730/2 and /inventory/{steamID}/730/16) are returning correctly — items are arriving in contextid 16 with valid assetids, just no way to map them back to the trade.

Anyone else seeing this? Currently falling back to inventory diff (snapshot before/after accept and matching new assetids by classid+instanceid+pos).

Hi, have the same problem for some trades from 22.04, 28.04 and for all trades since 29.04. new_assetid does not appear event after trade hold as I expected. Have someone fount a way to figure out new asset id when an asset is transfered to a counterparty?

looks like steam changed something for cs trades. Still works fine for dota2

yes, but all trading sites working fine

new_assetid should be present after trade hold ends

what is your assumption based on? the issue started appearing less than a week ago

[JVz]

its based on trades that were made more than a week ago so they are not on hold anymore

[G35]

can confirm that new_assetid is still shown on old trades. can't confirm if it appears on trades made on 29th or later (after this update), I guess we will have to wait for tradelocks to expire for confirmation.

I faced with this change on 22.04 first time. And there're still no new_assetid, new_contextid for trades from 22.04. The hold ended a long time ago

The getExchangeDetails response still doesn’t seem to include new_assetid, even after the trade protection period has ended.
