Error: Invalid access of closed

I don't quite understand how to fix this problem. Tell me please.

ws.send(JSON.stringify({uuid: ws.uuid}))
                        ^
 Error: Invalid access of closed uWS.WebSocket/SSLWebSocket.

The ws was closed. Looks like you have async open event, then you should add ws.closed=true in your close event and check it after doing any async

Вс закрыли. Похоже, у вас есть асинхронное событие открытия, тогда вы должны добавить ws.closed=true в событие закрытия и проверить его после выполнения любого асинхронного

does the attempt to send a message happen after the socket is closed?

[e3dio]

Yes you tried to send a message after it closed. Set ws.closed = true in the close event, and check ws.closed after doing async before sending message
