I'm trying to migrate my Magento 1.9.3.4 to Magento 2.2.2 with the data-migration-tool.
I did it and the store is working in localhost; I have the customers, sales, static pages and products.
I receive this fatal error when I tried to edit one product:
Fatal error: Uncaught TypeError: Argument 2 passed to Magento\Framework\View\Element\UiComponentFactory::argumentsResolver() must be of the type array, null given, called in D:\xampp\htdocs\magento2\vendor\magento\framework\View\Element\UiComponentFactory.php on line 212 and defined in D:\xampp\htdocs\magento2\vendor\magento\framework\View\Element\UiComponentFactory.php:164 Stack trace:

Some suggestion?
