gulp 4 spawn fails when building KSS

Question

I'm trying to resurrect my automated KSS build process which died a year ago after I upgraded Node for another project.

KSS works fine when I run it directly via the command line ($ ./node_modules/kss/bin/kss --config kss-config.json)

But when I run it via gulp using node spawn I get the following error:

user@computer /c/users/user/Documents/projects/kss
$ gulp
[12:04:42] Using gulpfile C:\users\user\Documents\projects\kss\gulpfile.js
[12:04:42] Starting 'default'...
[12:04:42] Starting 'compileKss'...
[12:04:42] 'compileKss' errored after 3.21 ms
[12:04:42] Error: spawn ./node_modules/kss/bin/kss ENOENT
    at Process.ChildProcess._handle.onexit (internal/child_process.js:264:19)
    at onErrorNT (internal/child_process.js:456:16)
    at processTicksAndRejections (internal/process/task_queues.js:80:21)
[12:04:42] 'default' errored after 6.78 ms

My gulp file looks like this:

'use strict'
/**
 * Some useful links to help with understanding this file:
 * * https://www.webstoemp.com/blog/switching-to-gulp4/
 */

const { series } = require('gulp')
const childProcess = require('child_process')

/**
 * a Gulp task for compiling Sass files to CSS and creating source maps
 */
const compileKss = (gulpCallBack) => {
  const kss = childProcess.spawn(
    './node_modules/kss/bin/kss',
    [
      '--config',
      './kss-config.json'
    ]
  )
  kss.on('exit', (code) => {
    const errorMsg = (code === 0) ? null : 'ERROR: kss-node process exited with code: ' + code
    gulpCallBack(errorMsg)
  })
  return kss
}

exports.default = series(compileKss)

and my kss config file looks like this:

{
  "title": "KSS style guide",
  "source": [
    "./style-guide/css/"
  ],
  "destination":  "./style-guide/",
  "homepage": "src/homepage.md",
  "builder": "node_modules/michelangelo/kss_styleguide/custom-template",
  "css": [],
  "js": []
}

and my package.json looks like this:

{
  "name": "KSS style-guide",
  "description": "KSS style-guide",
  "author": {},
  "browserslist": [
    "last 2 version",
    "> 1%"
  ],

  },
  "engines": {"node": ">=12"},
  "engineStrict": true,
