@2can

your newOffer event should be

processOffer(offer)

 Its better off you coding it yourself since you can learn your mistake and improve. Not by copying blindly from others and not knowing what is it doing

Edited May 3, 2020 by xLeeJYx
quote is too long

[Heateen]

manager.on('newOffer', (offer) => {
     processOffer(offer);
});

 

now it should work properly
