계속해서 JSON type 에 대한 에러 때문에
serialize 문제가 생기는 것 같다
그래서
json.dumps 를 쓰는 방법을 썼지만 해결되지 않았다.
문제는
Exception inside application: can not serialize 'UserLazyObject' object
Traceback (most recent call last):

async def receive(self, text_data):

await self.channel_layer.group_send(

'type': 'chat_message',
'message' : message,
'room_name' : room_name,
'user': self.scope['user']
}
) self.scope['user']
이 부분에서 문제가 생겼다
다른 예제를 보니
self.scope['user'].username
이렇게 사용하는 걸 보니 이부분에서 python type으로 보내진것으로
추측된다.
