I want my script to not automatically restart if there was an error. To only restart if it exited gracefully with exit code 0.

I created ecosystem.config.js in the script's folder and filled it with:

module.exports = {
  apps : [{
    name   : "My script",
    script : "./index.js",
    stop_exit_codes: [2]
  }]
}

So that when I use process.exit(2), it should stop the automatic restart.

However, it does not work and the script restarts automatically when I put this at the top of my script.

console.log("test");

process.exit(2);

So I tried using --stop-exit-codes instead:

pm2 start index.js --stop-exit-codes 2

But pm2 gives me this error:

error: unknown option --stop-exit-codes

How can I get the stop exit codes feature of PM2 to work?
