Parse Cloud httpRequest does not return a response

I am calling my Parse Cloud function from a js in my browser. I am doing merely as a test. I am trying to make a GET call to http://api.geonames.org . If I execute it in the browser as http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo it does work. It returns:

{"geonames":[{"fcodeName":"capital of a political entity","toponymName":"Mexico City","countrycode":"MX","fcl":"P","fclName":"city, village,...","name":"Mexiko-Stadt","wikipedia":"en.wikipedia.org/wiki/Mexico_City","lng":-99.12766456604,"fcode":"PPLC","geonameId":3530597,"lat":19.428472427036,"population":12294193},{"fcodeName":"capital of a political entity","toponymName":"Beijing","countrycode":"CN","fcl":"P","fclName":"city, village,...","name":"Peking","wikipedia":"en.wikipedia.org/wiki/Beijing","lng":116.397228240967,"fcode":"PPLC","geonameId":1816670,"lat":39.9074977414405,"population":11716620},{"fcodeName":"capital of a political entity","toponymName":"Manila","countrycode":"PH","fcl":"P","fclName":"city, village,...","name":"Manila","wikipedia":"en.wikipedia.org/wiki/Manila","lng":120.9822,"fcode":"PPLC","geonameId":1701668,"lat":14.6042,"population":10444527},{"fcodeName":"capital of a political entity","toponymName":"Dhaka","countrycode":"BD","fcl":"P","fclName":"city, village,...","name":"Dhaka","wikipedia":"en.wikipedia.org/wiki/Dhaka","lng":90.40743827819824,"fcode":"PPLC","geonameId":1185241,"lat":23.710395616597037,"population":10356500},{"fcodeName":"capital of a political entity","toponymName":"Seoul","countrycode":"KR","fcl":"P","fclName":"city, village,...","name":"Seoul","wikipedia":"en.wikipedia.org/wiki/Seoul","lng":126.9784,"fcode":"PPLC","geonameId":1835848,"lat":37.566,"population":10349312},{"fcodeName":"capital of a political entity","toponymName":"Jakarta","countrycode":"ID","fcl":"P","fclName":"city, village,...","name":"Jakarta","wikipedia":"en.wikipedia.org/wiki/Jakarta","lng":106.84513092041016,"fcode":"PPLC","geonameId":1642911,"lat":-6.214623197035775,"population":8540121},{"fcodeName":"capital of a political entity","toponymName":"Tokyo","countrycode":"JP","fcl":"P","fclName":"city, village,...","name":"Tokio","wikipedia":"de.wikipedia.org/wiki/Tokyo","lng":139.69171,"fcode":"PPLC","geonameId":1850147,"lat":35.6895,"population":8336599},{"fcodeName":"capital of a political entity","toponymName":"Taipei","countrycode":"TW","fcl":"P","fclName":"city, village,...","name":"Taipeh","wikipedia":"de.wikipedia.org/wiki/Taipei","lng":121.531846,"fcode":"PPLC","geonameId":1668341,"lat":25.047763,"population":7871900},{"fcodeName":"capital of a political entity","toponymName":"Bogotá","countrycode":"CO","fcl":"P","fclName":"city, village,...","name":"Bogotá","wikipedia":"en.wikipedia.org/wiki/Bogot%C3%A1","lng":-74.08175468444824,"fcode":"PPLC","geonameId":3688689,"lat":4.609705849789108,"population":7674366},{"fcodeName":"capital of a political entity","toponymName":"Hong Kong","countrycode":"HK","fcl":"P","fclName":"city, village,...","name":"Hong Kong","wikipedia":"en.wikipedia.org/wiki/Hong_Kong","lng":114.157691001892,"fcode":"PPLC","geonameId":1819729,"lat":22.2855225817732,"population":7012738}]}

Whereas if I execute it in my Cloud Code as:

Parse.Cloud.define("testRequest", function(request , response){
    Parse.Cloud.httpRequest({
        url: 'http://api.geonames.org/citiesJSON',
        params: {
            'north' : '44.1',
            'south' : '-9.9',
            'east' : '-22.4',
            'west' : '55.2',
            'lang' : 'de',
            'username' : 'demo'
        },
        success:function(httpResponse){
            console.log(httpResponse.text);
            response.success("success from response.success>>>>");
            console.log('httpResponse->'+ httpResponse.response +'  <<<');
            console.log('data>>'+httpResponse.data);
        },
        error:function(httpResponse){
            console.error('Request failed with response code ' + httpResponse.status);
            response.error(httpResponse.status);
        }, 
    });
});

With a script in my local machine of:

<script type="text/javascript">
    Parse.initialize("KEY", "KEY");



        Parse.Cloud.run('testRequest', {}, {
          success: function(result) {
            alert(result.httpRequest+"<----RESULT!")
            // result is 'Hello world!'
          },
          error: function(error) {
            alert("Something went wrong"+error.message);
          }
        });
  </script>

It returns a 200 status but no data. I made sure I deployed my code, and I see the latest code in the Cloud Code tab in Parse.com, so it's definitely not the case that I have old code running on the cloud.

Do you know how to correctly make a successful GET call from Cloud Code? Any help regarding this topic or helping me correcting any error in my code is greatly appreciated!

You should return the data from CloudCode by

response.success(httpResponse.text);

And use the data in JavaScript like this

Parse.Cloud.run('testRequest', {}, {
    success: function(result) {
        alert(result);
    }
});

You will see the result now.
