You are using memory therefore you are storing data in the memroy. you need to check what functions are you using that store data or fetch data. Does your bot is programmed to do a set of series every while? perhaps post a preview of your code so we can analyze.

Is calling SteamCommunity.checkConfirmations(); won't solve the issue?

Perhaps your application is not well designed?

Player #1 send offer to receive items from player #2. player #2 open steam client and click on accept. Prior confirming this offer, is the offer state remains as active? since createdNeedsConfirmation works for player #1 as he is sending his items to player #2.

Extracting the token from a trade url isn't a big issue, however I would stick to tokens since it's straight forward. if the token isn't validated means the token doesn't belong to the SteamID provided or is invalid. extracting a token can be as simple as it sounds, but i believe the act of sending an offer via a trade url is more of a hassle than sending an offer via tokens (as it needs more functions).

Hmm, I have multiple bots some doesn't have a phone. I'll do testing on a bot that is purely independent of mobile phones/desktop applications. Perhaps the one I used had mobile auth registered on an android device, not sure.

it's because of steam, you can use: setTimeout(function(){displayOfferUrl();}, 7000); on the client side, replace displayOfferUrl() with your own function(s) that will display the trade url, it will show the url after 7 seconds.

Can I provide my own device ID?

If you try to execute the bot using a user that doesn't have a home directory the application will crash on dataPath = path.join(process.env.HOME, ".local", "share", "{0}") perhaps check if process.env.HOME exists, otherwise set a fixed path?

empty as itemsToGive.length + itemsToReceive.length == 0?

Just realized one of the offers is stuck and the confirmation did not go through, is there a way around this as I'm only using SteamCommunity.startConfirmationChecker(12000, s); Would polling solve this issue? is there any other way around it?
