Plone 5.2 rc3 on Python 3.6.x: DateTime Error in portal_catalog

Hello,

I created a new Plone instance from Plone 5.2 rc3 and took a look into the indexes of the portal_catalog. If I try to browse in the indexes for 'created', 'effective', 'modified' and 'expired' I get only error messages with tracebacks similar to the following:

2019-05-31 11:03:38,299 ERROR [Zope.SiteErrorLog:251][waitress] 1559293418.29886650.8541733846348719 http://localhost:58585/[plone-site-name]/portal_catalog/Indexes/created/manage_browse

Is this a known issue with Plone 5.2 rc3 on Python 3.x?

Kind regards,
Andreas

This is a Zope related issue, not Plone related.
Please file an issue with the Zope bugtracker.

Thanks for your info. I filed an issue for Zope.

As far as I call: a Zope Datetime index is intended to index Zope DateTime objects. Plone uses in some places Python's datetime objects and uses the DateTime indexes for indexing purposes. The core indexing functionality seems to work however the ZMI may assume that the content is DateTime only instead of datetime.
