ngCordova camera upload to Amazon S3

I'm trying to upload an image taken from the iOS camera in ngCordova to a bucket on Amazon S3. I have no way of debugging this code. Im not sure if my problem is with S3 or my camera. Is there a way to debug an ionic/ngCordova app running on a device?

.controller('AddMediaCtrl', function($scope, $cordovaCamera) {

  //////////////////////////////////////////////////////////
  //                     AMAZON S3                       //
  ////////////////////////////////////////////////////////
    $scope.creds = {
      bucket: 'bucket_name',
      access_key: '*************',
      secret_key: '*************'
    }

    var bucket = new AWS.S3({params: {Bucket: $scope.creds.bucket }});
    AWS.config.update({accessKeyId: $scope.creds.access_key, secretAccessKey: $scope.creds.secret_key});
    AWS.config.region = 'us-east-1';

    var upload = function(file){

      results.innerHTML = '';

      var params = {Key: file.name, ContentType: file.type, Body: file};
      bucket.upload(params, function (err, data) {
        console.log(err);
      });
    }
