@p-netm @jasonrogena I think how pm2 manages processes may be interefering (or interfered with) by how we build versioned app directories.

We need to investigate this.

For now, I have run pm2 manually by pm2 start dist/index.js (I ran that from this directory /home/reveal-web-stage/express/server - anything else fails)

The systemd service is failing at the moment.
