    var prices: [Decimal]
}

_ = try req.content.decode(ProductRequest.self).map(to: Product.self) { postData in

}

  http://localhost:8080/product \
  -H 'Accept: application/json' \
  -H 'Cache-Control: no-cache' \
  -H 'Content-Type: application/x-www-form-urlencoded' \
  -H 'Postman-Token: 430b8984-a57f-4aec-9d40-ec772a8d2f86' \
  -d 'prices[]=10000.0&prices[]=20000.0'

This should be fixed by #9 (related to #10). Adding a test to make sure.
