To use Node Sequelize findOne to find the latest entry, we order the result by createdAt in descending order.
For instance, we write
model.findOne({
where: { key },
order: [["createdAt", "DESC"]],
});
to call findOne with order set to an array [["createdAt", "DESC"]] to order the result by createdAt in descending order to get the latest result.
