Property does not have corresponding setter in class Magento\Quote\Api\Data\AddressInterface while change checkout step

Question

1 - I add a eav attribute to customer_address

$attributesInfo = [
    'reference' => [
         'label' => 'Reference',
         'type' => 'varchar',
         'input' => 'text',
         'position' => 100,
         'visible' => true,
         'required' => false,
    ],
];

foreach ($attributesInfo as $attributeCode => $attributeParams) {
    $customerSetup->addAttribute('customer_address', $attributeCode, $attributeParams);
}

2 - I added the extension attribute in my module

<extension_attributes for="Magento\Quote\Api\Data\AddressInterface">
    <attribute code="reference" type="string"/>
</extension_attributes>

In my requirejs-config.js I override some javascript file to add reference field

var config = {
"map": {
    "*": {
        "Magento_Checkout/js/model/shipping-save-processor/default" : "Agr_Checkout/js/shipping-save-processor-default-override",
        "Magento_Customer/js/model/customer/address" : "Agr_Checkout/js/model/customer/address",
        "Magento_Checkout/js/model/address-converter" : "Agr_Checkout/js/model/address-converter",
        "Magento_Checkout/js/model/new-customer-address" : "Agr_Checkout/js/model/new-customer-address"
    }
}

3 - I confirm that the reference field is sending in address

4 - When i send my shipping information (Click on Next) I'm getting this error: "Property "Reference" does not have corresponding setter in class "Magento\Quote\Api\Data\AddressInterface"."

I already do: - Clean and flush magento cache - Run setup:upgrade - Run setup:di:compile

What I'm doing wrong?

Setting up attributes in an eav setup or upgrade script works best, and will automatically add to forms you request to add it to.

    class InstallData implements InstallDataInterface
    {
        private $_eavSetupFactory;
        private $_eavConfig;
        private $_attributeResource;
        protected $_logger;

        public function __construct(EavSetupFactory $eavSetupFactory, Config $eavConfig, Attribute $attributeResource, Monolog $logger)
        {
            $this->_eavSetupFactory = $eavSetupFactory;
            $this->_eavConfig = $eavConfig;
            $this->_attributeResource = $attributeResource;
            $this->_logger = $logger;
        }

        public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
        {
            $eavSetup = $this->_eavSetupFactory->create(['setup' => $setup]);
            $addressAttributes = [
        'attribute1' => [
            'type' => 'int',
            'label' => 'attribute1',
            'input' => 'text',
            'unique' => true,
            'required' => false,
            'visible' => true,
            'user_defined' => false,
            'position' => 100,
            'system' => false,
            'adminhtml_only' => 0
        ],
        'attribute2' => [
            'type' => 'int',
            'label' => 'attribute2',
            'input' => 'text',
            'required' => false,
            'visible' => true,
            'user_defined' => false,
            'position' => 110,
            'system' => false,
            'adminhtml_only' => 1
        ]
    ];

    $usedInFormsAddress = [
            'adminhtml_customer_address',
            'customer_address_edit',
            'customer_register_address'
        ];

    foreach ($addressAttributes as $code => $options) {
        $eavSetup->addAttribute(
            'customer_address',
            $code,
            $options
        );

        try {
            $attribute = $this->_eavConfig->getAttribute('customer_address', $code);
            $attribute->setData(
                'used_in_forms',
                $usedInFormsAddress
            );
            $this->_attributeResource->save($attribute);
        } catch (LocalizedException $exception) {
            $this->_logger->critical($exception->getMessage());
        } catch (Exception $exception) {
            $this->_logger->critical($exception->getMessage());
        }
    }

This code here will add to the forms and there won't be any issue saving or going to next step

$usedInFormsAddress = [
            'adminhtml_customer_address',
            'customer_address_edit',
            'customer_register_address'
        ];

try {
            $attribute = $this->_eavConfig->getAttribute('customer_address', $code);
            $attribute->setData(
                'used_in_forms',
                $usedInFormsAddress
            );
            $this->_attributeResource->save($attribute);
        } catch (LocalizedException $exception) {
            $this->_logger->critical($exception->getMessage());
        } catch (Exception $exception) {
            $this->_logger->critical($exception->getMessage());
        }

Answer 2

Try setting it via custom attributes.

Example:

...
 custom_attribute: [{"attribute_code": "reference", "value": "Your value"}]
...

Answer 3

how do you pass the attribute in the request? you can check browser console like that

{
    ...
    extension_attributes: {
         reference: "value"
    }
}

It's correct. You can remove var folder and generated folder var/cache var/page_cache var/view_proceed and generated/.
