Retrieves the most recently modified active Cart of a Customer with CartOriginCustomer. If no active Cart exists, this method returns a ResourceNotFound error.
If the Cart exists in the Project but does not have a `store` specified, or the `store` field references a different Store, this method returns a [ResourceNotFound](ctp:api:type:ResourceNotFoundError) error.
To ensure the Cart is up-to-date with current values (such as Prices and Discounts), use the [Recalculate](ctp:api:type:CartRecalculateAction) update action.
