Sorry, there is some context missing. These kinds of errors occur frequently during export migrations with collective.exportimport (which uses plone.restapi under the hood). The error usually occurs when you export...

The analysis is like this: The issue is clearly an index corruption that happened within a Plone migration after a series of plone.restapi calls. The affected field index is department...

There is no Python 2 in the game here. The ZODB was created from scratch under Python 3.7/Plone 5.2RC3

The issue is still pending (any annoying)...I still see the error in Plone 6.0.0a4: `/Users/ajung/src/plone6.buildout/eggs/ZODB-5.7.0-py3.9.egg/ZODB/blob.py:338: ResourceWarning: unclosed file `

At least in my case, there is no add-on code involved that would deal with blobs directly.
