The same error was thrown to me .This is because your peers are not connected and you are sending data.This was solved by this:

peer.on('connect', () => {
    console.log('I am connected now')
    peer.send('sending data blah blah')
  })

Add ondatachannel handling after removing {optional: [{RtpDataChannels: true}]}:

  myConnection.onicecandidate = function (event) { 

     if (event.candidate) { 
        send({ 
           type: "candidate", 
           candidate: event.candidate 
        });
     } 
  }; 

  myConnection.ondatachannel = function(event) {
     var receiveChannel = event.channel;
     receiveChannel.onmessage = function(event) {
        console.log("ondatachannel message:", event.data);
     };
  };

  openDataChannel();
