inventoryTransferDelete adds INVALID_STATE error code for transfers with in-progress product import

Starting in version 2026-07, the inventoryTransferDelete mutation will return a new error code: INVALID_STATE. This error will be returned when a client attempts to delete an inventory transfer while a product import related to that transfer is in progress.

• New error code added: INVALID_STATE
• API affected: inventoryTransferDelete mutation
• Error enum updated: InventoryTransferDeleteUserErrorCode

For older API versions, the mutation will not include the INVALID_STATE code in the error payload. However, the message field will still provide context about the blocking product import.

For more details, see the updated InventoryTransferDeleteUserErrorCode enum and the inventoryTransferDelete mutation documentation.
