Upload to S3 not showing in bucket

I'm trying to upload to S3 using aws-sdk and Node/Express. When I go through this process I get no errors and land on the "successfully uploaded" page. However the new file does not show up in my amazon bucket. Where am I going wrong?

Thank you for any help!

var aws             = require('aws-sdk');
var multerS3        = require('multer-s3');
var  multer          = require("multer");



aws.config.update({
    secretAccessKey: 'MYKEY',
    accessKeyId: 'MYKEY',
    region: 'us-east-2'
});

var s3 = new aws.S3();

var upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: 'medstayfiles',
    metadata: function (req, file, cb) {
      cb(null, {image: file.fieldname});
    },
    key: function (req, file, cb) {
      cb(null, Date.now().toString())
    }
  })
})

Posting

router.post('/', upload.array('photos', 1), function(req, res, next) {
  res.send('Successfully uploaded')
})
