WebRTC's CreateOffer appears to have broken the error handling

Question

I had a working implementation of WebRTC, using the Adapter.js pollyfill. It was previously working between Firefox and Chrome but now it appears to have a type error on the error handler. I had it set to use null, which still works in Chrome but Firefox now requires {} for an empty error handler (therefore breaking either Chrome or Firefox depending which I use). And it doesn't seem to work with an actual error handler either!
Example Code:
// Works in Firefox
pc.createOffer(function(description) {
console.log(description);
pc.setLocalDescription(description);
socket.emit('received_offer', JSON.stringify(description));
}, {}, mediaConstraints);
// Works in Chrome
pc.createOffer(function(description) {
console.log(description);
pc.setLocalDescription(description);
socket.emit('received_offer', JSON.stringify(description));
}, null, mediaConstraints);
