websocket-rails: Redis error when sending two different messages

Hey guys,

On my websocket controller, if I trigger two different websocket events, I get an error message about redis and the server exits. Take a look:

#the action of my websocket controller, triggered after an event
def action
  WebsocketRails['private_channel'].trigger 'received_chat_message', json #I'm sending to a priva channel here
  WebsocketRails.users[current_user.id].send_message('notify_received_message', 'other_message') #I'm sending to a specific user here
end

The weird thing is that If I comment one line out (doesn’t matter which one), it doesn’t give me any error. But if the two statements runs, I get:

This happens both in production and development. Any special reason?
