Magento 2 site, that had data transferred from a Magento 1.9 site.

When attempting to create a user, it fails with:

Class Magento\Eav\Model\Attribute\Data\Datetime does not exist

There are no entries that look like that in the eav_attribute table.

Is it looking for an eav_attribute in that table that isn't there? or is there an entry in another eav table that is making it look for a class somewhere?


The migration had brought over some customer eav attributes from a HORRIBLE module (FME Booking and Reservation). It was probably my fault for not mapping things correctly, however the solution was to delete the entries from the table customer_eav_attribute.

Hmmm..., You're config class-map incorrectly when migrate Magento 1 to Magento 2. You should be checked this attribute_code in Magento 1 and change it to:

    <!-- OR -->
  • Thanks Bill. As a last resort I will try the migration again. Do you have any idea how to correct this without a new migration? I don't understand where/how it's looking for this class. I don't see it in the database or anywhere in the code. Jan 4, 2018 at 13:29
  • You can see it on class-map.xml files
