amazon ec2 - Can't install PM2 services via Ansible on an Ubuntu EC2 instance

I'm using Ansible to create a pm2 service on a EC2 / Ubuntu instance. Below is the script. When I run it, PM2 is installed and the service is enabled. When I run pm2 list, I don't the see the service, but I can grep it (ps aux | grep node) and see that it's running. It also seems like a shadow copy of pm2 is running and loading the app, but I can't seem to control it.

- hosts: comm
  sudo: yes
  tasks:
    - npm: name=pm2 global=yes
    - name: configure pm2 to restart on startup
      shell: pm2 startup ubuntu >& /dev/null chdir=~/ executable=/bin/bash
      sudo: yes

      sudo_user: root
    - command: sudo env PATH=$PATH:/usr/bin pm2 startup ubuntu -u ubuntu
      sudo: yes
    - command: /usr/bin/pm2 save
    - command: /usr/bin/pm2 start /home/ubuntu/something/app.js --name something
