How to run ConPTY terminal from node.js pm2?

What's going wrong?

In node.js I use PTY terminal to run shells and capture its output text. Something like this

const pty = require('node-pty');
const AnsiTerminal = require('node-ansiterminal').AnsiTerminal;
const AnsiParser = require('node-ansiparser');
const Convert = require('ansi-to-html');

const shell = ptyProcess = pty.spawn('powershell.exe', ['-executionpolicy', 'remotesigned', '-File', 'test.ps1'], { name: 'test', cols: terminal_columns, rows: 30, cwd: __dirname, env: process.env });

var convert = new Convert({
    newline:true
});

const terminal_columns = 160;

var terminal = new AnsiTerminal(terminal_columns, 30, 500);
var parser = new AnsiParser(terminal);

ptyProcess.onData((data) => {
    const msg = data.toString();
    parser.parse(msg);
    const str = terminal.toString().trim() + "\n\n";
    var html_str = convert.toHtml(str);      
});

ptyProcess.onExit(function(data) {  
    // exit event
});

When I start the node program on a powershell terminal manually it works fine. But if I use pm2 to start the node program, it throws an error

Cannot create process, error code: 267

But if I create a regular shell like powershell.exe instead of the PTY one, it works fine.

How can I get pm2 to work with PTY?

Thanks

How could we reproduce this issue?

Run the above code from pm2.

Supporting information

Windows 10, node.js 10 latest

$ pm2 report

Reproduce the shown node-pty PowerShell example under PM2 on Windows 10 and compare it with running the same program manually. Investigate the ConPTY failure reporting error code 267, then verify that the PTY process starts successfully under PM2 without changing the regular-shell behavior.
