Error occurred during "shipping_address" processing on guest checkout

[sorinsinner]

I can't seem to get around this. Everything is working perfectly for logged in customer checkout (both frontend, and admin side).

But guest customer cannot place error with the following error coming up in the first step (Shipping) of checkout:

Error occurred during "shipping_address" processing. Error occurred during "customAttributes" processing. A custom attribute is specified with a missing attribute code. Verify the code and try again.

Can you help me figure this out? Checked on two different Magento 2.3 installations. One was fresh made just for testing this, and the other one is also 2.3 but with a theme applied.

Did you ever resolve this issue?

I have just found a solution. You need to rename the "customAttributes" key from the JSON that will be sent to guest-rest-api, with "custom_attributes".

Here you can find the documentation:
https://devdocs.magento.com/redoc/2.3/guest-rest-api.html#operation/checkoutGuestShippingInformationManagementV1SaveAddressInformationPost

Hey @IonutGorgos could you eloborate how does the issue is resolved? did you override core code

[IonutGorgos]

Hello,

I think that the solution wasn't to rename the "customAttributes" key. I did other things too. I will enumerate the steps.

1. You need to create another plugin for GuestPaymentInformationManagement. Copy and paste this code in etc/di.xml file.

<type name="Magento\Checkout\Model\GuestPaymentInformationManagement">
        <plugin disabled="false" name="Experius_ExtraCheckoutAddressFields_Plugin_Magento_Checkout_Model_GuestPaymentInformationManagement"
                sortOrder="10" type="Experius\ExtraCheckoutAddressFields\Plugin\Magento\Checkout\Model\GuestPaymentInformationManagement"/>
</type>

2. Create the file Plugin/Magento/Checkout/Model/GuestPaymentInformationManagement.php
   You can copy and paste the PaymentInformationManagement.php file from the same folder and just add the email param in the beforeSavePaymentInformation method.

beforeSavePaymentInformation method:

public function beforeSavePaymentInformation(
        \Magento\Checkout\Model\GuestPaymentInformationManagement $subject,
        $cartId,
        $email,
        PaymentInterface $paymentMethod,
        AddressInterface $address
    ) {
        $extAttributes = $address->getExtensionAttributes();
        if (!empty($extAttributes)) {
            $this->helper->transportFieldsFromExtensionAttributesToObject(
                $extAttributes,
                $address,
                'extra_checkout_billing_address_fields'
            );
        }
    }

3. Now, if you did all this steps, the following error will occur:
   "Property "0" does not have accessor method "get0" in class "Magento\Quote\Api\Data\AddressExtensionInterface"."
   That is because you need to do some changes in view/frontend/web/js/action/set-shipping-information-mixin.js

We need to have the extension_attributes key something like that:

{
 attribute_code1_key: "attribute_code1_value",
 attribute_code2_key: "attribute_code2_value",
 ....... ....... ....... ....... ....... ........
 attribute_codeN_key: "attribute_codeN_value",
}

4. Some changes in view/frontend/web/js/action/set-shipping-information-mixin.js:

            if (shippingAddress.customAttributes !== undefined) {
                $.each(shippingAddress.customAttributes, function (key, value) {

                    var attrCode = value['attribute_code'];
                    var attrValue = value['value'];

                    shippingAddress['customAttributes'][attrCode] = value;
                    shippingAddress['extension_attributes'][attrCode] = attrValue;
                });
            }

5. Some changes in view/frontend/web/js/action/create-shipping-address-mixin.js:

            if (messageContainer.custom_attributes != undefined) {
                $.each(messageContainer.custom_attributes , function( key, value ) {
                    messageContainer['custom_attributes'][key] = value;
                });
            }

6. Some changes in view/frontend/web/js/action/set-billing-address-mixin.js:

                if (billingAddress.customAttributes != undefined) {
                    $.each(billingAddress.customAttributes, function (key, value) {

                        var attrCode = value['attribute_code'];
                        var attrValue = value['value'];

                        billingAddress['extension_attributes'][attrCode] = attrValue;
                    });
                }

7. Don't forget the fieldset.xml and extensions_attributes.xml files.
