Configurable Products with Simple Products as configurations can't be added to cart

[mohan-nishit]

Hi Michiel,

Running this on a M2.4.0 website, I was able to complete the entire order flow using only simple products. If I go to any Configurable product with the configuration as shown in the screengrab below, I get an error on adding the product to the cart.

Here is the product Detail Page. I'm able to see the configurations in the dropdown:

And here is the error I get on adding to cart:

FWIW, the SKU in the GraphQL request to add the product seems to be wrong. It seems the label is sent instead of the SKU.

The Magento 2.4 GraphQL docs have an example where the data for "Variants" can be fetched: https://devdocs.magento.com/guides/v2.4/graphql/interfaces/configurable-product.html#extended-example

I added the variants data to the App\GraphQL class, under PRODUCT_CONTENTS, and sure enough it returned the variant data as per my expectations:

Question is, how to go about modifying the checkout flow to accommodate for the variants?

Hi @mohan-nishit,

Thanks for opening this issue. When developing the configurable functionality I couldn't find the logic on how to find the correct SKU for the selected combination. So at this moment, the generated SKU is based on the parent SKU + the selected options. This works on the Magento Sample Data. You can find the code where this is done here:
