Websocket Error: Исключение внутри приложения: объект 'set' не имеет атрибута 'decode'

Я изучаю Django для школьного проекта и пытаюсь создать сервер websocket, используя Django Channels с Daphne и Redis, но получаю ошибку "AttributeError: 'set' object has no attribute 'decode'"

При загрузке приложения происходит рукопожатие websocket и создается соединение, однако сразу после этого я отсоединяюсь от сервера со следующей ошибкой и трассировкой.

HTTP POST /chat/signin/ 200 [0.61, 127.0.0.1:54147]

Вот как настроен мой сервер

import chat.routing
import os

from channels.routing import ProtocolTypeRouter, URLRouter
from channels.security.websocket import AllowedHostsOriginValidator
from django_channels_jwt_auth_middleware.auth import JWTAuthMiddlewareStack
from django.core.asgi import get_asgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'core.settings')

django_asgi_app = get_asgi_application()

application = ProtocolTypeRouter({
    'http': django_asgi_app,
    'websocket': AllowedHostsOriginValidator(
        JWTAuthMiddlewareStack(
            URLRouter(chat.routing.websocket_urlpatterns)
        )
    )
})

Я пытался найти похожие вопросы, но все они вызывали атрибут decode, а я нет. Как я могу решить эту проблему?
