Why is my Parse subscription not receiving any events (not even 'open')? - node.js

Question

I am trying to host my parse server locally, but on my frontend I do not receive any events, not even the 'open' (connection opened) event. I also do not receive any errors that could help me solve the problem.
On my server I am using the following code:
var api = new ParseServer(
{
(... more properties and keys)
liveQuery:
{
classNames: ['Sticky', 'Canvas']
}
});
var app = express();
var mountPath = something;
app.use(mountPath, api);
var httpServer = require('http').createServer(app);
httpServer.listen(port, function(){ console.log('Running on http://localhost:' + port); });
var parseLiveQueryServer = ParseServer.createLiveQueryServer(httpServer);
On the frontend I am using the following code:
const stickyQuery = new Parse.Query(Sticky);
this.stickySubscription = await stickyQuery.subscribe();
console.log(this.stickySubscription); // This gets printed, nothing weird
this.stickySubscription.on('open', () => {
console.log('SUBSCRIPTION: opened'); // This is not printed
});
this.stickySubscription.on('create', (sticky) => {
console.log('SUBSCRIPTION: Sticky created, ', sticky); // This is also not printed
});
this.stickySubscription.on('update', (sticky) => {
console.log('SUBSCRIPTION: Sticky updated, ', sticky); // This is not printed
});
The subscription gets printed, and I don't see anything weird. It seems like connecting with the Parse server is going wrong. Does someone know what I'm missing or doing wrong?
Update: I added the following code to the frontend to show the websocket status and whether error events were triggered, but these events are also not triggered:
this.stickySubscription.on('close', () => {
console.log('SUBSCRIPTION: closed'); // This is not printed
});
Parse.LiveQuery.on('open', () => {
console.log('socket connection established'); // Gets printed
});
Parse.LiveQuery.on('close', () => {
console.log('socket connection closed'); // Is not printed
});
Parse.LiveQuery.on('error', (error) => {
console.log('socket error: ', error); // Is not printed
});

In your subscription query , write your className inside quotations:
const stickyQuery = new Parse.Query('Sticky');
