Error closing websocket connection

I can not catch the exception

from sanic import Sanic, Request, Websocket
from sanic.response import text
from sanic.exceptions import ServerError, WebsocketClosed

app = Sanic("xxx")

@app.websocket("/ws")
async def sanic_ws_handler(request: Request, ws: Websocket):
    remote_address = (request.ip, request.port)
    db_pool = request.app.ctx.db_pool
    try:
  
        while True:
            logger.debug('waiting for message from {}', remote_address)

            data = await ws.recv()
            if data is None:
                logger.debug('waiting for message from {} done, None',
                             remote_address)
                continue

            logger.debug('waiting for message from {} done, {} bytes',
                         remote_address, len(data))

            result = await message_handler.dispatch(data, remote_address,
                                                    db_pool)
            if result is not None:
                await ws.send(result)  
    except WebsocketClosed as e:
        logger.error("{} closed: {}", remote_address, e)
    except Exception as e:
        logger.error(f"{remote_address} exception: {e}")
    finally:
        try:
           #
            pass
        except Exception as e:
            logger.error('断开连接异常: {}', e)


app.run(host="0.0.0.0", port=18765, debug=False)

it sometimes throw exception
