Class adminhtml/catalog_product_helper_form_config does not exist but mentioned in: catalog_eav_attribute.frontend_input_renderer

When migrating from Magento EE 1.14.2.3 to Magento EE 2.1.8 I got this message:

Class adminhtml/catalog_product_helper_form_config does not exist but mentioned in: catalog_eav_attribute.frontend_input_renderer for attribute_id=110
Class adminhtml/catalog_product_helper_form_config does not exist but mentioned in: catalog_eav_attribute.frontend_input_renderer for attribute_id=134

Those two attributes are:

• gift_message_available
• gift_wrapping_available

Looking at those attributes in M2 I can see that the class being used as frontend_input_render for both is Magento\GiftWrapping\Block\Adminhtml\Product\Helper\Form\Config

Is this the right class?
Can someone confirm this?
If so, why adminhtml/catalog_product_helper_form_config is not mentioned in class-map.xml.dist?

Thank you @diazwatson for sharing this fix. I believe it occurs for those who updated to 1.14.2.3 from previous versions. Because if I install Magento EE 1.14.2.3 these attributes get

giftmessage/adminhtml_product_helper_form_config
enterprise_giftwrapping/adminhtml_product_helper_form_config

in frontend_input_renderer field and they are covered in class-map.xml.dist
Anyway, internal issue MAGETWO-71810 to fix your scenario.
