I've run into this issue after a data migration of 1.9.3.2 to 2.1.6
The error appears in the back-end when you try to access products in the catalog.
This was the closest thread I've come to anyone with a similar experience in data migrations. I've been up and down my eav_attribute table, but can't make any changes that'll remedy the issue.
