2 years ago Hi all
What is going on here is that, before the datachannel closes, the peers leaves the stream. In that case datachannel thinks the stream is still live and tries to send some data ( not important since you already left the stream, just ping like data ) and this error is logged since the stream is ended. You can just ignore this exception or close the data channel earlier while leaving such as;
Change following function in webrtc_adaptor.js (link: https://github.com/ant-media/StreamApp/blob/master/src/main/webapp/js/webrtc_adaptor.js#L605)
leaveFromRoom(roomName, streamId)
{
this.roomName = roomName;
var jsCmd = {
command : "leaveFromRoom",
room: roomName,
};
console.log ("leave request is sent for "+ roomName);
if (this.remotePeerConnection[streamId].dataChannel != null) {
this.remotePeerConnection[streamId].dataChannel.close();
}
this.webSocketAdaptor.send(JSON.stringify(jsCmd));
}Thanks
