Hi ,
You don't need to explicitly clear the registry cache. The cache will
automatically invalidate within 15 minutes. Or the cache will be cleared
when server is re started.
The issue you are facing is trying to access the cache using newly crated
tenant which causing a security issue. Seems like the owner of cache
instance still the old tenant.
Thanks!
