It doesn't return or upload original image

[ghost]

Subject of the issue

I run the example provided in the documentation, urls of resized images is returned but original image url is never returned. Along with resize images urls i get the error: InvalidArgument, statusCode: 400

Your environment

• Operating system Mac

• Node.js version (node --version) Node.js v6.x

• ImageMagick version (identify -version)

  ImageMagick v7.0.x

• s3-uploader version v2.x

Steps to reproduce

var client = new Upload('mybucket', {
            aws: {
                path: 'images/',
                region: 'us-west-2',
                acl: 'public-read',
                accessKeyId: '******************',
                secretAccessKey: '**********************',
                maxRetries: 5,
                retryDelayOptions: 2000,
                httpOptions: {
                    timeout: 240000
                }
            },
            returnExif: true,
            cleanup: {
                versions: true,
                original: false
            },

            original: {
                awsImageAcl: 'public'
            },

            versions: [
                {
                    maxWidth: 200,
                    maxHeight: 200,
                    aspect: '1:1',
                    format: extension.replace('.', ''),
                    suffix: '-small'
                },{
                    maxHeight: 45,
                    maxWidth: 45,
                    aspect: '1:1',
                    format: extension.replace('.', ''),
                    suffix: '-thumb'
                }
            ]
        });

        client.upload(req.files[0].path , {}, function(err, versions, meta) {
            if (err) { throw err; }

            versions.forEach(function(image) {
                console.log(image.width, image.height, image.url);

            });
        });

Expected behaviour

It should return thumbnails as well as original image url

Actual behaviour

it only returns thumbnails and throws exception
