printTask.execute not working on hosted application

[NovicaJosifovski]

I am trying to figure out why my printTask is not working when I host my .NET Core app on a server. It works locally, when I run the code via Visual Studio but not when I publish and host the app. 

For example, it works on line 12 in the code below. queryTask.execute(query).then(zoomToRoute) works but it does not work. I am not sure how or why it works when I run the app via Visual Studio but all I know is, it doesn't work when I host the app. Anyone with any insight will help me out, so please feel free to share any opinion.

function printMap() {
            require(["dojo/on", "esri/config", "esri/tasks/QueryTask", "esri/tasks/query", 'esri/symbols/SimpleMarkerSymbol', "esri/symbols/SimpleLineSymbol", "esri/Color", 'esri/geometry/Extent', "esri/tasks/PrintTask", "esri/tasks/PrintParameters", "esri/tasks/PrintTemplate", "dojo/domReady!"],
                function (on, esriConfig, QueryTask, Query, SimpleMarkerSymbol, SimpleLineSymbol, Color, Extent, PrintTask, PrintParameters, PrintTemplate) {
                    console.log("globalParcel :: " + globalParcel + " reportType :: " + reportType + " globalScale :: " + sentScale);
