Multiple files not working properly

[RoosterH]

Hi,

Thanks very much for creating this wonderful package.
I tried it with multiple sizes yesterday. It worked when the request has one file. When there are multiple files, it doesn't seem to work.

In router, I am using:

fileUploadResizeS3.fields([
	{ name: 'eventImage', maxCount: 1 },
	{ name: 'courseMap', maxCount: 1 }
]),

fileUploadResizeS3 is where I define multer-sharp-s3:

const fileUploadResizeS3 = multer({
	limits: 1500000, 
	storage: s3Storage({
		ACL: 'public-read', 
		s3: s3,
		Bucket: process.env.S3_BUCKET_NAME,
		metadata: (req, file, cb) => {
			const ext = MIME_TYPE_MAP[file.mimetype];
			cb(null, { fieldName: file.fieldname });
		},
		Key: (req, file, cb) => {
			const UUID = uuid();
			const ext = MIME_TYPE_MAP[file.mimetype];

			let S3Folder;
                          .........

			cb(null, S3Folder + '/' + UUID + '.jpg');
		},
		multiple: true,
		resize: [{ suffix: 'small', width: 300 }, { suffix: 'original' }],
		toFormat: { type: 'jpeg', options: { quality: 100 } }
	}),
	fileFilter: (req, file, cb) => {
		const isValid = !!MIME_TYPE_MAP[file.mimetype];
		let error = isValid ? null : new Error('Invalid MIME type!');
		cb(error, isValid);
	}
});

It did return 2 file arrays:

req.files =  [Object: null prototype] {
  eventImage: [
    {
      fieldname: 'eventImage',
      originalname: 'Bowser.jpg',
      encoding: '7bit',
      mimetype: 'image/jpeg',
      small: [Object],
      original: [Object]
    }
  ],
  courseMap: [
    {
      fieldname: 'courseMap',
      originalname: 'CourseMap.png',
      encoding: '7bit',
      mimetype: 'image/png',
      small: [Object],
      original: [Object]
    }
  ]
}

The problem is files inside of eventImage are actually coureMap files. CourseMap files are empty, 0 byte.

Please look into this issue and let me know if you need more information.

Thanks again!
