在Magento 2中更新后，客户自定义属性将被删除

Question

从前端的“客户我的帐户”部分更新客户信息时遇到问题，即“客户自定义”属性在更新或保存客户信息时被删除。

为此，我根据此链接创建了一个插件-https://github.com/magento/magento2/issues/6411

代码编译后，我面临以下错误-

Fatal error: Uncaught TypeError: Argument 1 passed to Vendor\Customization\Plugin\saveCustomCustomerAttributes::__construct() must be an instance of Magento\Customer\Model\AttributeMetadataConverter, instance of Magento\Framework\ObjectManager\ObjectManager given, called in /htdocs/stage6/html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93 and defined in /htdocs/stage6/html/app/code/Vendor/Customization/Plugin/SaveCustomCustomerAttributes.php:35 Stack trace: #0 /htdocs/stage6/html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(93): Vendor\Customization\Plugin\saveCustomCustomerAttributes->__construct(Object(Magento\Framework\ObjectManager\ObjectManager)) #1 /htdocs/stage6/html/vendor/magento/framework/ObjectManager/Factory/Compiled.php(88): Magento\Framework\ObjectManager\Factory\AbstractFactory->createObject('Vendor\\Cust...', Array) #2 /htdocs/stage6/html/vendor/magento/framework/ObjectManager/ObjectManager.php(71): Magento\Framework\ObjectManager\Factor in /htdocs/stage6/html/app/code/Vendor/Customization/Plugin/SaveCustomCustomerAttributes.php on line 35

下面是我的代码-

请提供一些建议。
