// routeID extracts the ID from the request URL. If the ID is not in a valid

// from the handler. the validate.ErrInvalidID error is known by the error middleware
// and will be handled accordingly.

// Example: /api/v1/ac614db5-d8b8-4659-9b14-6e913a6eb18a -> uuid.UUID{ac614db5-d8b8-4659-9b14-6e913a6eb18a}
