Puppet errors

Hiya Katello/Foreman folks!

Sooo, I've inherited an instance here at work, and it has seemed to have
broken, (the puppet end of it, I can build machines, but they're left
unconfigured, and management of existing machines has also broken)…

after running the following:
[PROD:root@uldcp-katello01:~/katello]# katello-installer
–certs-update-server
Marking certificate
/root/ssl-build/uldcp-katello01.teletech.com/uldcp-katello01.teletech.com-apache
for update
Marking certificate
/root/ssl-build/uldcp-katello01.teletech.com/uldcp-katello01.teletech.com-foreman-proxy
for update

it fails with the following:
(from /var/log/katello-installer/katello-installer.log)
[ERROR 2017-07-06 23:56:27 main] Could not find any content at
puppet:///modules/foreman/external_node_v2.rb
[ERROR 2017-07-06 23:56:27 main]
/Stage[main]/Foreman::Puppetmaster/File[/etc/puppet/node.rb]/ensure:
change from absent to file failed: Could not find any content at
puppet:///modules/foreman/external_node_v2.rb

So, I'm wondering if any of you have seen this before?

(running foreman version 1.10.4, and katello version 2.4)

Thanks in Advance!
