All Repos fail to sync PLP0000: can't compare datetime.datetime to NoneType

Problem:
All repos fail to sync, exception error: Katello::Errors::PulpError: PLP0000: can’t compare datetime.datetime to NoneType
Expected outcome:
Successful Repo sync
Foreman and Proxy versions:
Foreman 1.24.3
Foreman-tasks 0.17.5
Pulp Version 1.5.0
Pulp server version 2.21.5
Katello 3.14.1

Distribution and version:
CentOS 7.9.2009
Other relevant data:
Recent system change was a yum update all resulting in the pulp services failing to start with an error: “Pulp Fail with error: pulp.server.db.migrate.models:ERROR: pulp.server.db.migrations hasn’t been updated to the latest available migration.”
Resolved pulp not starting by reverting the pulp.server.db.migrations version back one version which has now resulted in none of the repos syncing with the PLP0000: can’t compare datetime.datetime to NoneType error.

Performing a ‘yum update all’ on your system definitely would require you to run the foreman-installer to ensure that everything is in the correct state if any of the foreman+katello packages changed. Can you give that a try (ie foreman-installer --scenario katello), do a foreman-maintain service restart at the end, and see if that gets you running again?

Could not find a solution to this and so had to rebuild the server
