Here's the function that raises the exception.

    def send_message(self, text_data):

       session_id = self.scope['url_route']['kwargs']['session_id']

       AsyncToSync(self.channel_layer.group_send)(

           'chat-{0}'.format(session_id),

           {

               "type": "chat.message",

               "text": text_data,

           },

       )

Hi,

Sorry about this, it was a bug in the group_send method. It's been fixed in channels_redis version 2.0.2.
