Live query with include won't work

I have a table, one of the table fields points to the users table, here is my code:

var subscription = (new Parse.Query('Queue')).include('requestingUser').subscribe();
subscription.on('create', function(queueObject) {
    queueObject.get('requestingUser') // user object
    queueObject.get('requestingUser').get('name') // undefined
})

Within the parse server index.js I set:

liveQuery: {
    classNames: ["_User", "User", "Queue"] // Just in case I did try "_User" and "User"
}

I also tried another table, other than users table, doesn't work either.

This is the response(if it helps):

Honestly, I'm not sure if it's a bug but I was trying to find out if it's even possibly to use include with live query and didn't find anything like that in the docs, but the docs suggest that subscribe is just instead of find for example so I don't think include should be a problem and it is.

Start with the liveQuery configuration in index.js and reproduce the Queue subscription using the requestingUser include shown in the issue. Trace how Parse.Query(...).include(...).subscribe() handles related objects and compare the result with the reported response. Done means establishing whether includes are supported for live queries and resolving or clearly documenting the observed behavior.
