                    break;
                }
            }

    }
}

It can be because of registering domain to somewhere in QuickBlox settings but can't see this kind of step in documentation as well as in Quickblox Admin Portal.

Please help!!

Hi @tarungomile ,
As the error says - you're trying to assign a function to false. This can happen if you're trying to assign some handler to webrtc module while QB JS SDK is not yet initialized or if WebRTC is not available. In such case QB.webrtc will have value false.
