DeliveryAddressInput requires exactly one of delivery_address, customer_address_id

[JoseDinkbit]

When I send direction in null, I have the error DeliveryAddressInput requires exactly one of delivery_address, customer_address_id. Can I send the direction in null or I have to send at least one direction?

Hi @JoseDinkbit could you confirm which mutation you're using?

Hi, my query is:

        val checkout = CartInput()
        checkout.setBuyerIdentityInput(
            Input.value(
                Storefront.CartBuyerIdentityInput()
                    .setEmail(email)
                    .setDeliveryAddressPreferences(
                        listOf(
                            DeliveryAddressInput().setDeliveryAddress(
                                address
                            )
                        )
                    )
                    .setCustomerAccessToken(DataTemp.getInstance().accessToken?.token)
            )
        )

    return Storefront.mutation { query ->
        query.cartCreate({ cartCreate ->
            cartCreate.input(
                checkout
            )
        }) { cartCreate ->
            cartCreate.cart { checkoutQuery ->
                checkoutQuery.checkoutUrl()
            }.userErrors { errorQuery ->
                errorQuery.code()
                    .field()
                    .message()
            }
        }
    }

But, when i send the address in null, I had that error, but I found the solution, it was dont send the deliveryAddress parameter.

Thanks a lot.

Thanks for sending that, delivery address isn't required in buyer identity input, e.g. any of these would be accepted:

{ buyerIdentity: { deliveryAddressPreferences: [] }
{ buyerIdentity: { deliveryAddressPreferences: null }
{ buyerIdentity: {} }

But this would be treated as invalid:

{ buyerIdentity: { deliveryAddressPreferences: [ {} ] }

Looking at the code I think you'll likely need to avoid calling setDeliveryAddress() where address is null to avoid seeing the validation message.

There's an example of setting delivery address preferences in the sample app that might help.
