How to reload the configuration after starting the configuration update?

What's going wrong?

How to reload the configuration after starting the configuration update "cwd" field?

ecosystem.config.js：

{
  "apps": [
    {
      "name": "app",
      "cwd": "/data/demo",
      "instances": 1,
      "exec_interpreter": "/bin/node",
      "exec_mode": "fork",
      "log_date_format": "YYYY-MM-DD HH:mm:ss",
      "error_file": "/logs/app-err.log",
      "out_file": "/dev/null",
      "env": {
        "NODE_ENV": "production"
      }
    }
  ]
}

When I change the cwd field and run pm2 startOrReload ecosystem.config.js --only app, I run pm2 info app to see that cwd field is not updated.

Now I must delete and restart to update. Is there a more friendly way to reload it?

Reproduce the behavior with ecosystem.config.js and pm2 startOrReload ecosystem.config.js --only app, then inspect the result with pm2 info app. Trace how the cwd field is handled during reload. Done means changing cwd and reloading updates the process configuration without deleting and restarting the app.
