title: Parse-Server LiveQuery not sending events
body: <p>I am trying to get live queries working with iOS and Parse-Server. The following is my setup for my Parse-Server:</p>
  <pre><code>...
  
  let api = new ParseServer({
      databaseURI: databaseUri || constants.DATABASE_URI,
      cloud: process.env.CLOUD_CODE_MAIN || constants.CLOUD_CODE_MAIN,
      appId: process.env.APP_ID || constants.APP_ID,
      masterKey: process.env.MASTER_KEY || constants.MASTER_KEY,
      serverURL: process.env.SERVER_URL || constants.LOCAL_SERVER_URL,
      fileKey: process.env.FILE_KEY || constants.FILE_KEY,
      appName: process.env.APP_NAME || constants.APP_NAME,
      publicServerURL: process.env.SERVER_URL || constants.LOCAL_SERVER_URL,
      liveQuery: {
          classNames: [Parse.User]
      }
  });
  
  ...
  
  let port = process.env.PORT || 1337;
  
  let httpServer = require('http').createServer(app);
  httpServer.listen(port, function () {
      console.log('parse_server running on port ' + port + '.');
  });
  
  ParseServer.createLiveQueryServer(httpServer, {logLevel: 'VERBOSE'});
  
  ...
  </code></pre>
  <p>And this is my code in the iOS app:</p>
  <pre><code>let liveQueryClient = ParseLiveQuery.Client(server: &quot;ws://serverurl/&quot;, applicationId: &quot;appID&quot;, clientKey: &quot;clientKey&quot;)
  
  let query = PFUser.query()?.whereKey(&quot;objectId&quot;, equalTo: &quot;ABC123&quot;) as! PFQuery&lt;PFUser&gt;
  
  let subscription = self.liveQueryClient.subscribe(query).handle(Event.updated) { _, user in
      debugprint(&quot;\(user)&quot;)
  }
  </code></pre>
  <p>Debugging on local, I can see the user is connecting using the socket because the server logs:</p>
  <pre class="lang-none prettyprint-override"><code>info: Create new client: 0
  </code></pre>
  <p>and when I disconnect, the server logs:</p>
  <pre class="lang-none prettyprint-override"><code>info: Client disconnect: 0
  </code></pre>
  <p>My problem is that whenever I modify the User object in Parse Dashboard, nothings logs on the server side, and the client doesn't receive any events.</p>
  <p>Is there another way to set this up?</p>
  <p>Can the User class not be used in live queries?</p>
