Print widget implementation : TypeError issue with PrintTask.js

This print widget is blocked before creating an output. The combobox properly retrieves the print task url, but the console shows "TypeError: b is undefined" for http://js.arcgis.com/3.17/esri/tasks/PrintTask.js:25:13.

 

Map is created in Map.js

 

var map;
var baseMapLayerWorld;

require([
"esri/map", "esri/dijit/Search", "esri/layers/ArcGISDynamicMapServiceLayer","esri/layers/FeatureLayer", "esri/InfoTemplate", "dojo/domReady!"
], function (Map, Search, DynamicMapServiceLayer, FeatureLayer, InfoTemplate) {

baseMapLayerWorld = new esri.layers.ArcGISTiledMapServiceLayer("http://services.arcgisonline.com/arcgis/rest/services/World_Street_Map/MapServer");

map = new Map("map", {
center: [-150, -17], // lon, lat
zoom: 8
});

map.addLayers([baseMapLayerWorld);
});

 

The print widget is implemented in Print.js:

 

var app = {};
require([
"esri/map", "esri/layers/FeatureLayer",
"esri/dijit/Print", "esri/tasks/PrintTemplate",
"esri/request", "esri/config",
"dojo/_base/array", "dojo/dom", "dojo/parser",

"dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!"
], function(
Map, FeatureLayer,
Print, PrintTemplate,
esriRequest, esriConfig,
arrayUtils, dom, parser
) {
parser.parse();

app.printUrl = "https://sampleserver6.arcgisonline.com/arcgis/rest/services/Utilities/PrintingTools/GPServer/Export%20Web%20Map%20Task";

esriConfig.defaults.io.proxyUrl = "http://our-server/Java/proxy.jsp";

// get print templates from the export web map task
var printInfo = esriRequest({
"url": app.printUrl,
"content": { "f": "json" }
});
printInfo.then(handlePrintInfo, handleError);

function handlePrintInfo(resp) {
var layoutTemplate, templateNames, mapOnlyIndex, templates;

layoutTemplate = arrayUtils.filter(resp.parameters, function(param, idx) {
return param.name === "Layout_Template";
});

if ( layoutTemplate.length === 0 ) {
console.log("print service parameters name for templates must be \"Layout_Template\"");
return;
}
templateNames = layoutTemplate[0].choiceList;

// remove the MAP_ONLY template then add it to the end of the list of templates
mapOnlyIndex = arrayUtils.indexOf(templateNames, "MAP_ONLY");
if ( mapOnlyIndex > -1 ) {
var mapOnly = templateNames.splice(mapOnlyIndex, mapOnlyIndex + 1)[0];
templateNames.push(mapOnly);
}

// create a print template for each choice
templates = arrayUtils.map(templateNames, function(ch) {
var plate = new PrintTemplate();
plate.layout = plate.label = ch;
plate.format = "PDF";
plate.layoutOptions = {
"authorText": "Made by: Esri's JS API Team",
"copyrightText": "<copyright info here>",
"legendLayers": [],
"titleText": "Pool Permits",
"scalebarUnit": "Miles"
};
return plate;
});

// create the print dijit
app.printer = new Print({
"map": app.map,
"templates": templates,
url: app.printUrl
}, dom.byId("print_button"));
app.printer.startup();
}

function handleError(err) {
console.log("Something broke: ", err);
}
});
