How can I edit the SKU of a variant using GraphQL?

[Eric-HAN]

Hi, there

The sku field is in the InventoryItem .you could refer to this

mutation UpdateProductVariantSKU {
  productVariantUpdate(input: {
    id: "gid://shopify/ProductVariant/xxxxxx",
    inventoryItem: {
      sku: "xxxxxxxxx"
    }
  }) {
    productVariant {
      id
      sku
    }
    userErrors {
      field
      message
    }
  }
}
