I'm currently in the process of migration a Magento 188.8.131.52 project to Magento 2.2.2.
During Data migration I get this error:
SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '21-152' for key 'EAV_ENTITY_ATTRIBUTE_ATTRIBUTE_SET_ID_ATTRIBUTE_ID'
My understanding is that there are 2+ duplicate entries
21-152 in the
eav_entity_attribute table for columns
attribute_id - so I thought to just delete the duplicate.
But there is no duplicate entry with that value in the source database...in fact, there is no such value in that table (in any column).
While in the destination database, this table is completely empty.
So I'm really not sure what the problem is or how to fix it...
Does anyone know what
Duplicate entry 21-152 means exactly?
Or if someone could suggest an approach how to handle this issue?
