Exception when client disconnects from server

[stas-andr]

Hello, I use WebsocketServer from ypy-websockets:

    while True:
        try:
            async with (
                WebsocketServer(log=logger) as websocket_server,
                serve(
                    my_ws_handler(websocket_server),
                    GeneralConfig.WS_SERVER_HOST,
                    5567,
                    ping_interval=None,
                ),
            ):
                await asyncio.Future()
        except Exception as exp:
            global PREV_COUNT_CLIENTS_WS
            print(websocket_server.rooms)
            PREV_COUNT_CLIENTS_WS = 0
            logger.error(str(exp))
            logger.info('Restart server')

When my client disconnects, the server crashes due to the below fault. I had to restart the server, what are the alternatives?
Error:
