Description
I set up Soketi on docker server and when i send this pattern of message with postman to soket disconnect my connection and docker container down! and show this error!
((1006 Abnormal Closure:No close frame was received.))
Actually, I enter the wrong channel index and I want to avoid this type of errors

{ "event":"pusher:subscribe", "datsa":{ "auth":"app-key:0c080bf328ca9fd6b54c00d7fe14480c5c55ede03a995ae0afe4399feedd8fd4", "channels":"private-notification.user.65214916d365f04e880c24f5" } }
How can I prevent this from happening?
