Failed to set remote offer sdp: Called with SDP without DTLS fingerprint. about bowser

[Firegarden]

I have seen this before because I had the same issue. I believe I solved it by checking if the connection was stable before creating the offer. Eg.

pc.onnegotiationneeded = function () {
if (pc.signalingState === STABLE) {
trace('CreateOffer: ' + toUser);
pc.createOffer(function (offer) {

Bowser has the bug that the offer created by createOffer does not have any
fingerprint in it. A workaround is to do setLocal, and then send off the
pc.localDescription (which is an SDP with fingerprint info) to the other
side.

There is a PR to fix this bug,
EricssonResearch/openwebrtc#427, it seems I need
some help to get it reviewed and (hopefully) merged - perhaps you can say
you'd want this merged?

I just can't remember how I resolved this. Now that you say that I feel
like I had to make sure I didn't actually use the offer or answer in my
signaling rather I used the pc.localdescription

pc.createOffer(function (offer) {
pc.setLocalDescription(offer,
function () {

_signalChannel.server.signalOffer(toUser, _userName, _connectionId,
JSON.stringify({ 'data': pc.localDescription })); // NOTE I am NOT passing
the offer.

pc.setRemoteDescription(new RTCSessionDescription(offer.data), function () {
pc.createAnswer(function (answer) {
pc.setLocalDescription(answer,
function () {

_signalChannel.server.signalAnswer(fromUser, _userName, _connectionId,
JSON.stringify({ 'data': pc.localDescription })); // I am NOT using the
answer again pc.localDescription

stefhak - I commented on the pull request. Is there any other place I should post to show support?
