Issue NodeJS extension not starting any process

[Emanuele Coppola]

Hello,
I'm relatively new to plesk since I used some older version and then now my company bought it again since it got better.

What I'm trying to achieve is a fully workng NodeJS application using Plesk.
I tried first with my application, but no proceeses was spawning.

Then I tried to install both of your demo applications here. Everything is set properly but no NodeJS process is spawning.

It looks like Passengers is not starting and when I see the Nginx logs there's this.

When I do "ps aux | grep node" I can't see any Node process.
When I run the start process from the "Run script" button it works fine, but then it doesn't use the Environment variables.
