Running AdminUI, when trying to add a new OIDC client or show an old one, the AdminUI reports:
An error occurred while displaying this page.
The AdminUI logs report the error:

This issue happens after doing a Parallel Upgrade, where the Policy Server and the AdminUI 12.9 have been installed, and they are pointing to the old and not upgraded Policy Store 12.8SP8CR01.
The root cause of this issue is that the AdminUI and Policy Server run with the Policy Store with data structure 12.8SP8CR01.
As per documentation, the Policy Store data should be upgraded to 12.9 before using the AdminUI 12.9 with it (1).
The main reason is that to work correctly, the AdminUI 12.9 expects the data definition from 12.9.
As a Parallel Upgrade, a new Policy Store should be set up with the data definition from Policy Server 12.9, before being able to run the AdminUI 12.9 (1).
Install and configure a new Policy Store, and then run the command XPSExport and XPSImport to replicate the old Policy Store to the new one in a Parallel Upgrade path (2)(3).
