#WebSocket DISCONNECT /ws/server/ [127.0.0.1:56029

I have a problem with HANDSHAKING consumer.

class WSServerConsumer(JsonWebsocketConsumer):
    START_CMD = 'start'
    STOP_CMD = 'stop'

    def __init__(self, *args, **kwargs):
        super(WSServerConsumer, self).__init__(*args, **kwargs)
        self.active_channels = {}

    def get_channel(self, name):
        channel = self.active_channels.get(name)
        if not channel:
            self.register_channel(name)
        return self.active_channels.get(name)

    def register_channel(self, name):
        self.active_channels[name] = FactoryChannel.get_channel_instance(name)

    def handler_message(self, event):
        channel = self.get_channel(event['channel'])
        if channel.is_open:
            self.send_json(
                {
                    'channel': channel.name,
                    'response': event['result']
                })

    def connect(self):
        print('START')
        self.accept()
        # await self.send('Hello client!')

    def disconnect(self, code):
        print('CODE: %s' % code)
        self.close()

    def receive_json(self, content, *args):
        action = content.get('action')
        channel_name = content.get('channel')
        init = content.get('init')

        channel = self.get_channel(channel_name)

        channel.switch(action)
