Issue

The customer can’t update cart items because of a GraphQL UpdateCartItems mutation error.

Steps to reproduce:

  1. Create a configurable product (MH01) by assigning one simple (MH01-XL-Gray).

  2. Go to the Commerce Admin > Catalog > Products > SKU > MH01 > Customizable Options.

  3. Add a custom option to the product.

    • Option Title: Option1
    • Option Type: Field
    • Required: Yes
    • Price: 10.00
    • Price Type: Fixed
    • SKU: MHC1
    • Max Characters: 25

  4. Run the below GraphQL query to generate cart ID.

    code language-graphql 
    mutation {
  createEmptyCart
}

  5. Make a note of the cart ID code.

  6. Run the below query to add configurable product to the cart:

    code language-graphql 
    mutation {
addConfigurableProductsToCart(
input: {
    cart_id: "<cart ID from above step>",
    cart_items: [{
    parent_sku: "MH01",
    data: {
        quantity: 1,
        sku: "MH01-XL-Gray"
        },
        customizable_options: {
            id: 1,
            value_string: "2"
            }
        }
    ]
}
)
{
cart {
  items {
    uid
    quantity
    product {
      name
      sku
    }
    ... on ConfigurableCartItem {
      configurable_options {
        option_label
      }
    }
  }
}
}
}

  7. You will notice that the cart is populated with the configurable item.

  8. Make a note of the uid returned.

  9. Again, run the below query to update the cart item.

    code language-graphql 
    mutation {
  updateCartItems(
    input: {
      cart_id: "<cart ID from previous step>",
      cart_items: [
        {
          cart_item_uid: "<uid from previous step>"
          quantity: 3,
          customizable_options:[{
              id: 1,
              value_string: "67"
          }]
        }
      ]
    }
  ){
    cart {
      items {
        uid
        product {
          name
        }
        quantity
      }
      prices {
        grand_total{
          value
          currency
        }
      }
    }
  }
}

  10. Observe the response.

Expected results:

The cart is updated without any issue.

Actual results:

You get the following error:

{
  "errors": [
    {
      "message": "Could not update cart item: You need to choose options for your item.",
      "extensions": {
        "category": "graphql-input"
      },
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "updateCartItems"
      ]
    }
