I installed Magento 2.4.2

According to Magento GraphQL DevDocs updateCartItems mutation cart_item_id is Deprecated. Use cart_item_uid instead. The unique ID assigned when a customer places an item in the cart.

I can not get cart item's uid from customerCart and cart query.

Please help me.

check release notes: https://devdocs.magento.com/guides/v2.4/release-notes/open-source-2-4-2.html#graphql

  • Yes i installed and use magento 2.4.2 but i can't get uid. Please help me.
