Any idea?

beshoo commented 3 years ago

As I can see the panic start on //github.com/Rhymen/go-whatsapp@v0.1.2-0.20210331105008-20ff81390fcd/conn.go:240 err := wac.ws.conn.Close() But I can not understand how com wac.ws.conn is nil.

How can I reproduce this?

danielspk commented 3 years ago

Try to reproduce the panic without success. It occurred unexpectedly without any handlers being called according to the application logs.

Will this be related to a gorilla/websocket fix?

Well, I tried also, Anyway... it is normal to have such cases, you need to set a service to check if go-whatsapp is working or not, if not, just restart the service.

Just use SYSTEMCTL, works for me. http://maratgaliev.com/go-service/
