can you help?

[cforsyth68]

Same problem. No solution?

[harshitrathod1]

not showing dual window

socket.on('user-connected',(user_id) => { console.log("Hey someone just Joined" + user_id); setTimeout(connectToNewUser,1000,user_id,stream); //connectToNewUser(user_id,stream); });

wrap connectToNewUser function with a setTimeOut function as stream object is null if we don't use it. Navigator promise takes time to create a stream object and we are calling connectToNewUser function before stream has been created!
