This is from https://community.theforeman.org/t/changing-puppet-master-for-multiple-hosts/30946

Problem:
When I select multiple hosts and click on action “Change Puppet Master”, all I get is the modal with the circling image. I can see in the firefox dev tools that it calls the URI /foreman_puppet/hosts/select_multiple_puppet_proxy and gets 500 error.

Expected outcome:
List of hosts to change puppet master.

Foreman and Proxy versions:
foreman-3.4.0-1.el8.noarch
katello-4.6.0-1.el8.noarch
rubygem-hammer_cli_foreman_puppet-0.0.6-1.fm3_4.el8.noarch
