Ошибка Not Implemented в слоях каналов Django

Я следовал руководству Django channels tutorial для создания простого приложения чата. Но при попытке проверить, может ли канальный слой подключиться к Redis, я получаю эту ошибку Not Implemented Error.

>>> async_to_sync(channel_layer.send)('test_channel', {'type': 'hello'})

Конфигурация канальных слоев:

ASGI_APPLICATION = 'justchat.asgi.application'
CHANNEL_LAYERS = {
    'default': {
        'BACKEND': 'channels_redis.core.RedisChannelLayer',
        'CONFIG': {
            'hosts': [('redis://127.0.0.1, 6379')]
        },
    },
}

Redis Server запущен: Redis Server

Я следую этому руководству с самого начала, и мой код такой же, как там. Что мне делать?

В конфигурации допущена опечатка:
