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
