when running npm commands, the process name is always shell

What's going wrong?

I am trying to run several projects with pm2 using npm scripts, but each process name is always "shell" even when explicitly set in a json config.

How could we reproduce this issue?

have a config like

{
  "apps": [
    {
      "name": "api-server",
      "script": "npm",
      "args": "run start"
    },
}

and notice that the process's name is "shell" and not "api-server"

No source file, test, or entry point is identified in the report. Reproduce the issue with the shown PM2 JSON configuration and npm command, then trace how PM2 names npm-launched processes; done means configured names such as "api-server" appear in the PM2 list instead of "shell".
