User class instantiation in livequery is initiated

Is it possible to initialize the user class in a live query? I have initialized the user class in my index.js and it shows up in my network inspector. However, when I attempt to query, nothing appears in the websocket.

Below is the code showing how I initialize the live query:

var user = new Parse.Query('_User');
user.equalTo('email', $scope.currentUser.attributes.email);
user.include('money');
userSubscription = user.subscribe();

For incorporating LiveQuery into your parse-server, follow these steps:

  1. Ensure that the _User class is registered under LiveQuery classes within your ParseServer initialization (usually in the NodeJS index.js file). Add any additional classes to the array as needed

    liveQuery: {
      classNames: ['_User']
    }

  1. Start the Parse live query server with the following code:

let httpServer = require('http').createServer(app);
httpServer.listen(port);
var parseLiveQueryServer = ParseServer.createLiveQueryServer(httpServer);

  1. In your JS client, use the following approach:

script
let query = new Parse.Query('_User');
let subscription = query.subscribe();

subscription.on('open', () => {
  console.log('open event');
});

subscription.on('update', (object) => {
  console.log('user object updated!');
});

Additional events like 'create' and 'enter' are available. Refer to this guide for more details on usage.
