Question Getting user's name on a sent trade

[Meshi8]

Hey,

 

so I'm trying to get user's personaName in a sent trade offer.

 

I'm pretty sure I'm doing this right, but I can't figure out what's causing the error..

manager.on("sentOfferChanged", (OFFER, OLDSTATE) => {
	
	OFFER.getUserDetails((err, me, them) => {
               theirname = them.personaName;
		console.log(theirname);	

});
});

What error?
