Error after upgrading to latest version

23 Jul 2021

      I have three Uyuni servers that I've updated to the latest version.  The first two went well.  The third fails on the startup of Tomcat.  This one was from an older revision.  The other two were running an Uyuni version at Leap 15.2, but the one with the problem was old enough to be on 15.1.
I did "zypper up susemanager"
Ran server-migrator.sh
Then ran pg-migrate-10-to-13.sh
All completed with no errors.

On restart, there is an issue with Tomcat.  This appears in the most recent catalina log:
