Question

您好，有人可以向我解释此错误。它适用于本地机器，也可以在本地使用heroku时使用因为它是在heroku生产上运行的，它给了我这个错误，我已经完成了所有的测试，并试图获得更多的错误数据，但没有运气。

有什么用途：heroku，sidekiq，actioncable，ruby on rails 5.0.1

room_channel.rb

class RoomChannel < ApplicationCable::Channel
 def subscribed
  stream_from "room_channel"
 end

 def unsubscribed
 # Any cleanup needed when channel is unsubscribed
 end

 def speak(data)
  Message.create! content: data['message'], user: current_user
  end
 end

BroadcastMessageJob.rb

class BroadcastMessageJob < ApplicationJob
queue_as :default

def perform(message)
 ActionCable.server.broadcast 'room_channel', render_message(message)
end

private
def render_message(message)
 ApplicationController.renderer.render message
 end
end

model message.rb

 class Message < ApplicationRecord

提前谢谢。

有人可以给我一些关于这个actioncable错误的指示吗？
