InvalidStateError: Failed to set remote answer sdp: Called in wrong state: kStable

hey there,

I have implemented simple-peer.js and I have the error when I send the answer : InvalidStateError: Failed to set remote answer sdp: Called in wrong state: kStable

Here is my config :

let p = new Peer({
  			 initiator: initiator,
  			 stream: stream,
  			 config:
  			  {
			    'iceServers': [
				     {
				      'urls': 'stun:eu-xxxxx.com'
				    },
				    {
				      'urls': 'turn:eu-xxxxx=udp',
				      'credential': 'xxxxxxxx',
				      'username': 'xxxxxx'
				    },
				  ]
				},
  			 trickle:false
  			})

Have you an idea to fix this error ?

I have tracked down the issue by pure luck. Since most of us are probably started off the same tutorials… the issue only happens with more than 2 connections (peers). And the issue is this:

    onSignalingMessage = data => {
        let msg = JSON.parse(data);
    
        // make sure the message is for us
        // this lines were missing but without this it's broken
        if (msg.from != this.peerClient)
            return;
    
        // ... handling connection-answer, new-ice-candidate here ...
    }

The peerClient and msg.from are arbitrary Identifier of your peer between your javascript and the signaling server.

Basically what happens is you are trying to set an answer or ice-candidate on the wrong peer and they don’t like it 😃

Hope this helps.

my error was because i was accidentally creating peer with the current user’s connectionId instead of the connectionId of the user im trying to connect to…
