Virtual type does not exist but mentioned in

[bobdavison]

Magento 2.2.1, Migration Tool 2.2.1

I am getting the following error:
ERROR: Class Simplyhops\ProductAdmin\Model\Config\Source\Variety does not exist but mentioned in: eav_attribute.source_model for attribute_id=257

I have looked at the Migration Troubleshooting page and suggestions in issue #144.

This error is related to a new attribute in my Magento 2 code, it is not migrated but the migration tool seems to move it to a new attribute id and the volume check attempts to validate it. The class does not exists as it is a virtual type configured in my di.xml.

I have tried adding the effected attribute into the ignore section of eav-attribute-groups.xml and adding an empty class map to class-map.xml but to no avail.

I have got round this by providing a custom Migration\Step\Eav\Volume sub-class via config.xml that changes line 153 to also check if the ObjectManager can create an instance of the type.

It is not a great solution as it instantiates the objects rather than just checking that they are valid but it works for now.

@bobdavison I am also getting similar error below. Can you please help to fix it ?

Class Magento\Catalog\Block\Adminhtml\Product\Helper\Form\BaseImage does not exist but mentioned in: catalog_eav_attribute.frontend_input_renderer for attribute_id=74

I already tried after adding below in class-map.xml.dist but it didn't work.

<rename>
    <from>Magento\Catalog\Block\Adminhtml\Product\Helper\Form\BaseImage</from>
    <to />
</rename>

@kp-drc your problem is unrelated, the BaseImage class does not exist as it was removed from Magento between versions 2.0 and 2.1

You could set the offending frontend_input_renderer to null in the catalog_eav_attribute table but you should consider upgrading to a newer release of Magento 2.

@bobdavison I am using Magento 2.2.2. It is already latest.

@kp-drc your problem is unrelated to this issue and you already have your own issue open. If I can help I will comment on your issue.
