calculatematrix using the javascript API rather than REST - mootools

Question

I'm trying to use the calculatematrix API to take a load of destinations and calculate the driving distance to them from a given location (my examples first convert the postcode to a latlng)
Using the REST api and JQuery I can get this to work fine. See this JSFiddle - https://jsfiddle.net/vostrx9m/
$.ajax({
url: 'https://geocoder.api.here.com/6.2/geocode.json',
type: 'GET',
dataType: 'jsonp',
jsonp: 'jsoncallback',
data: {
app_id: 'XHHvADl4hLUQWLbUOGNp',
app_code: '-Zhl4CYrM03JxXabdROElA',
searchtext: 'TR9 6QA'
},
success: function(data) {
var LatLon = data.Response.View[0].Result[0].Location.NavigationPosition[0].Latitude + "," + data.Response.View[0].Result[0].Location.NavigationPosition[0].Longitude;
$.ajax({
url: 'https://matrix.route.api.here.com/routing/7.2/calculatematrix.json',
type: 'GET',
dataType: 'jsonp',
jsonp: 'jsoncallback',
data: {
mode: 'fastest;truck;traffic:disabled;',
start0: LatLon,
destination0: '50.395118,-4.934356',
destination1: '50.464852,-5.031908',
destination2: '50.541548,-4.938789',
app_id: 'XHHvADl4hLUQWLbUOGNp',
app_code: '-Zhl4CYrM03JxXabdROElA',
summaryAttributes: 'distance,traveltime'
},
success: function(data) {
for (i in data.response.matrixEntry) {
$('p').append("dest(" + i + "), " + data.response.matrixEntry[i].summary.distance + " meters, " + data.response.matrixEntry[i].summary.travelTime + " seconds<br\>");
}
}
});
}
});
However our site uses MooTools, so I've rewritten this against mootools and I now get CORS issues. "has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status." It looks like the preflight gets a permission error - see this JSFiddle here - https://jsfiddle.net/1av2wkye/5/
getDistancesFromPostCode('TR84LP')
function getDistancesFromPostCode(StartPostCode) {
console.log('getDistancesFromPostCode: ' + StartPostCode)
var req = new Request({
method: 'get',
url: "https://geocoder.api.here.com/6.2/geocode.json",
data: {
app_id: 'XHHvADl4hLUQWLbUOGNp',
app_code: '-Zhl4CYrM03JxXabdROElA',
searchtext: StartPostCode
},
onComplete: function(data) {
console.log(data)
var StartLatLon = data.Response.View[0].Result[0].Location.NavigationPosition[0].Latitude + "," + data.Response.View[0].Result[0].Location.NavigationPosition[0].Longitude;
console.log(StartLatLon)
getDistancesFromLatLng(StartLatLon)
},
}).send();
}
function getDistancesFromLatLng(StartLatLon) {
console.log('getDistancesFromLatLng: ' + StartLatLon)
var req = new Request({
method: 'get',
url: "https://matrix.route.api.here.com/routing/7.2/calculatematrix.json",
data: {
mode: 'fastest;truck;traffic:disabled;',
start0: StartLatLon,
destination0: '50.4153650,-5.0698703',destination1: '50.4154830,-5.0698890',destination2: '50.473036820553446, -4.707902895605457',
app_id: 'XHHvADl4hLUQWLbUOGNp',
app_code: '-Zhl4CYrM03JxXabdROElA',
summaryAttributes: 'distance,traveltime'
},
onComplete: function(data) {
console.log(data)
for (i in data.response.matrixEntry) {
console.log("dest(" + i + "), " + data.response.matrixEntry[i].summary.distance + " meters, " + data.response.matrixEntry[i].summary.travelTime + " seconds<br\>");
}
},
}).send();
}
Any ideas what MooTools is doing wrong or how I fix that?
If not, I tried a different tactic by writing things against the Javascript API and I got the geoencode working, but I cannot see any reference to the calculatematric API in the JavaScript documentation, any ideas?
Thanks

As the request should be a JSONP type request , i would guess using Request.JSONP from MooTools should help with the CORS issue. HERE Javascript API does not have support for the calculate matrix end point of the API.
