WebSocket connections with undefined properties | Deno | Page 1

Every client trying to create a socket connection with my Deno Socket Server seems to give undefined values for everything. I don't know if this is client sided or server sided (Both clients connected are using different socket libraries for different languages, Javascript and Python)
