File Transfer loses params option when using SSL

[metalaureate]

When I run the following code without SSL, params is passed as expected. When I run the same code and the same endpoint but with SSL, params is not passed. Can anyone else reproduce that?

 var options = {
                fileKey: 'photo1',
                fileName: 'imageName.jpg',
                httpMethod: 'POST',
                params: {user_id: user.user_id}
            };

 $cordovaFileTransfer.upload(AppConfig.apiHost + "/api/photo/", filePath, options,true)
                .then(function (result) {
                    // Success!
                    $log.debug(result);
                    deferred.resolve(result);

                }, function (err) {
                    // Error
                    $log.debug(err);
                    deferred.reject(err);
                }, function (progress) {
                    // constant progress updates
                    $log.debug(progress);

                });

I am using Cordova 6.0, Ionic 1.0.
