I am having problems trying to replace the QueryTask for the 4.24 release, since tasks are no longer supported. I was able to do this for Identify and GeometryService tasks, but the query one is not working for me.
I am using the 4.23 version of the javascript api, and would like to upgrade to 4.24.  The issue here is that I cannot seem to create a constructor for rest/query, and my query code all is in a separate module, not within the require block. It's a fairly complex application, and the query module itself is over 1000 lines of code, dynamic html, etc. So I've always created a constructor for the querytask, and used that in the query module. That doesn't seem to be possible now, unless I'm missing something.

I made a stripped down version of this here: https://codepen.io/jsauder/pen/ExLXLYq just showing how the constructor for the query cannot be created, and passed to javascript outside of the require block. If there is a way to do this, I would greatly appreciate if anyone could share this. Thanks in advance for any assistance you may be able to provide.

The abbreviated setup below is probably along the lines of what you're looking for:

var queryTask;
var queryObj;

require(["esri/rest/query/executeQueryJSON","esri/rest/support/Query"], function(QueryTask, Query) {
	queryTask = QueryTask;
	queryObj = new Query();

	//other stuff
});

function runPolygonQuery(qIdx, qErr) {
	//other stuff

	queryTask.executeQueryJSON(sQryUrl+"/" + qIdx, queryObj);
)

The new query doesn't have a constructor, so instead of creating it using "new query", you have to use the createQuery method on a FeatureLayer.
