Issue with sent offer changed


Recommended Posts

manager.on("sentOfferChanged", (offer, oldstate) => {
  let oldState = TradeOfferManager.ETradeOfferState[oldstate];
  let currentState = TradeOfferManager.ETradeOfferState[offer.state];
  //console.log(offer.partner.getSteamID64());
  console.log(
    green,
    `Sent offer state changed from ${oldState} to ${currentState}`
  )};

Output:

Sent offer state changed from CreatedNeedsConfirmation to InvalidItems
Sent offer state changed from CreatedNeedsConfirmation to InvalidItems
Sent offer state changed from CreatedNeedsConfirmation to Accepted

So basically, I sent 2 trades from my BOT Account to 2 different accounts. The problem is both the trades changed their current State to InvalidItems when one of the offers was accepted and then later on that trade was confirmed. Why did both the trades emit InvalidItems? I am not able to replicate this issue again. Is this common? and is there any way to avoid this? Thanks

Steam is Steam and Steam sucks. It happens sometimes and you should probably either delay a little while before marking a trade as definitively closed, or otherwise allow for reopening trades in whatever system or database you're using if the offer should become Accepted.

What would be the best way to confirm a trade has 100% completed if there is no margin for error?

I've never seen a trade offer go from Accepted to some other state and actually mean that the trade didn't go through. Once it goes to Accepted you're pretty safe to say that it's completed.

It used to be possible for trades to go to InvalidItems after Accepted, but the trade had still gone through. I don't think that's possible anymore though.

I should mention, if you want to be absolutely sure that a trade completed (and hasn't been rolled back), you should take the tradeID property from the trade offer and plug it into GetTradeStatus. The values for the status property are documented here in ETradeStatus.

Or just use getExchangeDetails.

Thanks for your insights

Sorry for this huge code with only small parts of your modules. But if you can confirm if the way in which I've handled this trade can there be a chance for error? Thank you for your help
