Upgrading Ansible Tower to 3.5. failed on database schema migration stage

[Jia Sian Lee]

Trying to upgrade existing Ansible Tower from version 3.2.5 to 3.5.01 using the bundled installer but ran into the following problem during the upgrade (using setup.sh):

Did a search on " RuntimeError: dictionary changed size during iteration" and couldn't found anything related to the Ansible Tower upgrade. Has anyone encountered this before?

This is not the list for Tower, contact RedHat for support.
