Error pop up screen after input username and password in Aperture. WebAdmin login works normally.
Error screen may look like:
This happened immediately after upgrade to 17.2. Following the steps from this KB:
After enabling the showStackTrace option, and running directly on the server box, a new error message was received:
HTTP Status Code
Message From Server
Query; reflection initializer failed: see inner exception for additional information. InnerException: Attribute 'Validation State' is an unknown attribute definition; CacheEntryNotFound Parameter name: name
This error message means that a Product schema definition was not found, indicating that some schema update(s) during the upgrade process failed.
Run VCC.exe again, and select the Configure Products option. This will re-import all the product schema and add any missing definitions. Once VCC completes, restart IIS on all servers running the TPP web services to refresh the cache on each of them. After that, login to Aperture should work normally.
