	router.get('/', (req, res) => {
	const { product_id } = req.query;
	ProductMeta.findOne({product_id})
	.then((metaData) => {
	const inputCharac = metaData.characteristics;
	const outputCharac = {};
	inputCharac.map((charac) => {
	if (charac.count) {
	outputCharac[charac.name] = {
	value: charac.avgValue,
	count: charac.count,
	id: charac.characteristic_id
	};
	}

	metaData.characteristics = outputCharac;
	res.status(200).send(metaData);
	})
	});

It looks like there is is no catch for this DB transaction so if it fails the client would never get a response. Remember to always send back a response even when there is an error.
