  </code></pre>
  
  <p>I have commented out the consumers.py completely just to first solve this error so there are no consumers at the moment</p>
  
  <p>Library Versions</p>
  
  <pre><code>Channels 2.2.0
  asgiref 2.2.0
  redis 2.10.6
  asgi-redis 1.4.3
  </code></pre>
  
  <p>The other question I have is, is it not absolutely necessary to have a channel layer? because in the tutorial I am following they are setting no channel info in the settings.py. Does the latest channels library manage this under the hood?</p>
