Storefront cartDiscountCodesUpdate missing checkoutUserErrors

[Lennart-Franck]

Hey, 

as of Storefront API version 2024-04 the Checkout API’s will be marked as deprecated. The deprecated checkoutDiscountCodeApplyV2 has the return field checkoutUserErrors which also states error codes for why a discount code may not applied. The new alternative cartDiscountCodesUpdate does not have this field and therefore there is no way of indicating why a code was not applied. 

Is there a way of finding out, why a discount code was not applied if it was not applied. 

Thanks.
