All of my servers are failing when running the puppet agent, the puppetmaster returns an error that the ENC script (the node.rb script for Foreman) is returning exit code 127.

I'm not entirely certain what exit code 127 is, as the script itself is configured to return exit code 1 on failure it appears. Puppet has a colon after the error code like it is expecting to display more details but ... (more)

Exit code 127 indicates that the shell that executes your ENC script cannot locate an executable in the PATH variable. Have your environment variables changed since working on the other issue that you mentioned?

Since the script succeeds even when running it as the puppet user (assuming you are using su - puppet <rest of command>), can you post any relevant log output in case there is a clue contained within?

I finally solved this by using 'env' at the top of my nginx configuration file to manually set PATH and locale-related environment variables. These passed through to Puppetmaster via Passenger and made things work again.

I still don't know why it suddenly stopped working and required me to manually set these vars, but nonetheless, if you're in the same position I was, that was the solution that worked.
