从 Magento 1.9.2.1 迁移到 2.4.6，一切顺利，尝试在后端查看产品时出现问题（前端没有显示），我收到类型错误并且不确定如何解决此问题。
页面在尝试查看或编辑产品时显示此错误：
TypeError: Magento\Framework\View\Element\UiComponent\DataProvider\Sanitizer::sanitizeComponentMetadata(): Argument #1 ($meta) must be of type array, null given in /var/www/magento2/vendor/magento/framework/View/Element/UiComponent/DataProvider/Sanitizer.php:85

我已经重新编译、重新编制索引并清除了缓存，但没想到这会解决问题。
问题出在您的数据库上，对于某些产品，元属性为空，所以这就是您看到此错误的原因。
