Invalid data passed to 'loop', it requires a list

[alexanderjacuna]

Expected Behavior

When executing the command: ansible-playbook site.yml -i inventory/my-cluster/hosts.ini I was expecting the playbook to complete as seen in the video tutorials. Instead it is getting hung up during the app armor task.

Current Behavior

Steps to Reproduce

1. Following steps detailed in https://www.youtube.com/watch?v=CbkEWcUZ7zM
2. Made adjustments to enable Proxmox LXC usage.
3. Ran the command: ansible-playbook site.yml -i inventory/my-cluster/hosts.ini
4. Seeing the following output...

Possible Solution

• [x] I've checked the General Troubleshooting Guide

[alexanderjacuna]

Adding the inventory/my-cluster/group_vars/proxmox.yml file.

Archive this issue. I think I need to double check my work. I expect that I'll need to open another issue but let me confirm a couple more things. Will open another issue if needed.
