SOLUTION:
https://puppet.com/docs/pe/latest/installing_agents.html
Add classes to the PE Master node group for each agent platform used in your environment. For example, pe_repo::platform::el_7_x86_64.
If that doesn't work, try deploying the production environment.
puppet access login --service-url https://$(hostname -f):4433/rbac-api --lifetime 5d
puppet code deploy production --wait
