title: How to avoid console error 403 when backend not give return
body: <p>If I set my channel like this, I get console error 403. <br>
  note:: if ($user-&gt;status) isn't reg.</p>
  <pre><code>Broadcast::channel('using', function ($user) {
      if($user-&gt;status=='reg'){
         return $user-&gt;id;
      }
  });
  </code></pre>
  <p>If I set my channel like this, everything is okay.</p>
  <pre><code>Broadcast::channel('using', function ($user) {
      if($user-&gt;status=='reg'){
          return $user-&gt;id;
      }else{
          return 'invalid';
      }
  });
  </code></pre>
  <p>But I need to set my channel when $user-&gt;status isn't reg, I don't want to give any return. <br>
  <strong>Problem</strong> is if I don't give any return, I get console error 403. <br>
  <em>Sorry for my english skill</em></p>
