Issue

Two parallel requests in GraphQL for adding the same configurable product to the cart resulted in two separate items on the cart with the same product SKU.

Steps to reproduce:

  1. Create a configurable product with SKU Test and a simple product with SKU Test-A.

  2. Create a new empty cart via GraphQL (change the location with your own URL):

    code language-graphql
    curl --location 'http://mag.local/graphql' \
    --header 'Store: default' \
    --header 'Content-Type: application/json' \
    --data '{"query":"mutation{\n createEmptyCart\n}","variables"{}}'
    
  3. Run two concurrent requests to add the same product to the cart (change cartID and location for both requests):

    code language-graphql
        curl --location 'http://mag.local/graphql' --header 'Store: default' --header 'Content-Type: application/json' --data '{"query":"mutation($cartId: String!, $preSku: String!, $preParentSku: String!) {\r\n addConfigurableProductsToCart(\r\n input: {\r\n cart_id: $cartId\r\n cart_items: [\r\n {\r\n parent_sku: $preParentSku\r\n data: {\r\n quantity: 1\r\n sku: $preSku\r\n }\r\n }\r\n ]\r\n }\r\n ) {\r\n cart {\r\n items {\r\n id\r\n product {\r\n name\r\n sku\r\n }\r\n quantity\r\n \r\n prices {\r\n price {\r\n value\r\n currency\r\n }\r\n }\r\n ... on ConfigurableCartItem {\r\n configurable_options {\r\n option_label\r\n value_label\r\n }\r\n }\r\n }\r\n total_quantity\r\n prices {\r\n grand_total {\r\n value\r\n currency\r\n }\r\n discounts {\r\n amount {\r\n value\r\n currency\r\n }\r\n label\r\n }\r\n subtotal_excluding_tax {\r\n value\r\n currency\r\n }\r\n } \r\n }\r\n }\r\n}","variables":{"cartId":"VV85vRfmCrRm0aKLKkNDrXH2S5y7sSpf","preParentSku":"Test","preSku":"Test-A"}}' & curl --location 'http://mag.local/graphql' --header 'Store: default' --header 'Content-Type: application/json' --data '{"query":"mutation($cartId: String!, $preSku: String!, $preParentSku: String!) {\r\n addConfigurableProductsToCart(\r\n input: {\r\n cart_id: $cartId\r\n cart_items: [\r\n {\r\n parent_sku: $preParentSku\r\n data: {\r\n quantity: 1\r\n sku: $preSku\r\n }\r\n }\r\n ]\r\n }\r\n ) {\r\n cart {\r\n items {\r\n id\r\n product {\r\n name\r\n sku\r\n }\r\n quantity\r\n \r\n prices {\r\n price {\r\n value\r\n currency\r\n }\r\n }\r\n ... on ConfigurableCartItem {\r\n configurable_options {\r\n option_label\r\n value_label\r\n }\r\n }\r\n }\r\n total_quantity\r\n prices {\r\n grand_total {\r\n value\r\n currency\r\n }\r\n discounts {\r\n amount {\r\n value\r\n currency\r\n }\r\n label\r\n }\r\n subtotal_excluding_tax {\r\n value\r\n currency\r\n }\r\n } \r\n }\r\n }\r\n}","variables":{"cartId":"VV85vRfmCrRm0aKLKkNDrXH2S5y7sSpf","preParentSku":"Test","preSku":"Test-A"}}'
    
  4. Get the cart to see the items (change cartId and location):

    code language-graphql
    curl --location 'http://mag.local/graphql' \
    --header 'Store: default' \
    --header 'Content-Type: application/json' \
    --data '{"query":"{\n cart(cart_id: \"VV85vRfmCrRm0aKLKkNDrXH2S5y7sSpf\") {\n items {\n id\n product {\n name\n sku\n }\n quantity\n }\n\n }\n}\n","variables":{}}'
    

Expected results:

Item listed once with qty = 2.

    {"data":{"cart":{"items":[{"id":"5","product":{"name":"config1","sku":"config1"},"quantity":2}]}}}%

Actual results:

Item listed twice with qty = 1.

    {"data":{"cart":{"items":[{"id":"1","product":
    {"name":"config1","sku":"config1"},"quantity":1},
    {"id":"3","product":{"name":"config1","sku":"config1"},"quantity":1}]}}}%
