Hey there,
we are trying to build a free gift with purchase functionality leveraging the LineUpdate operation of the Cart-Transform Function API. This works fine for normal products but I noticed that when using a Gift Card this error is shown in the checkout blocking it completely:
The function itself does not throw an error, but the request for adding the gift product to the has the following response: {"status":422,"message":"Cart Error","description":"The bundle product 'Gift Card - 10€' cannot be added to the cart."}the product is added regardless and shown as free in the cart on the storefront.
Is this a normal and expected behavior?
