# Updated CalculateExchangeLineItemInput and CalculatedExchangeLineItem Variant nullability

As of Admin GraphQL API `2025-01` version, `CalculateExchangeLineItemInput.variantId` and `CalculatedExchangeLineItem.variant` fields are nullable at schema level.

This is in preparation of future feature changes. In the current state `CalculateExchangeLineItemInput.variantId` will still be validated via a returned error if not present.
