title: TypeError: Invalid attempt to destructure non-iterable instance
body: <p>I'm new in this project and I'm trying to use the <code>react-redux-universal-hot-example</code> API, but using my code:</p>
  
  <pre><code>export function showMessage() {
    return {
      type: SHOW_MESSAGE,
      promise: (client) =&gt; client.get('/posts')
    };
  }
  </code></pre>
  
  <p>I get this error in my browser:</p>
  
  <p><code>TypeError: Invalid attempt to destructure non-iterable instance</code></p>
  
  <p>Can anyone help?</p>
