python应用websockets模块，范例代码出错

导入了websockets模块，用https://pypi.org/project/websockets/主页上的客户端和服务端范例代码跑了一下

服务端

import asyncio

import websockets



async def echo(websocket, path):

    async for message in websocket:

        await websocket.send(message)



asyncio.get_event_loop().run_until_complete(

    websockets.serve(echo, '192.168.0.100', 8765))

asyncio.get_event_loop().run_forever()

客户端

#!/usr/bin/env python



import asyncio

import websockets



async def hello(uri):

    async with websockets.connect(uri) as websocket:

        await websocket.send("Hello world!")

        await websocket.recv()



asyncio.get_event_loop().run_until_complete(

    hello('ws://192.168.0.100:8765'))

server和client都能正常运行
但是client一旦运行超server发送数据的时候，server就会报异常

异常信息:

求指教
