/**
 * Based on the GraphQL query, this method returns a Magento <code>Products</code> object
 * that "matches" the data expected by each CIF component. Each CIF component indeed expects a
 * specific JSON response. Luckily, each GraphQL query sent by each component is different so
 * we can "detect" what response should be returned.
 * 
 * @param env The metadata of the GraphQL query.
 * @return A Magento <code>Products</code> object.
