Armbian 23.11.1 Cannot read properties of null (reading 'destroy')

[dzianisv]

I tried to run an example from the readme.md in this repo

user@orangepipc:~/wakeword$ node wake.js
/home/user/wakeword/node_modules/@mathquis/node-personal-wakeword/src/detector.js:253
    this._vad.destroy()
              ^

TypeError: Cannot read properties of null (reading 'destroy')
    at WakewordDetector.destroy (/home/user/wakeword/node_modules/@mathquis/node-personal-wakeword/src/detector.js:253:15)

    at listOnTimeout (node:internal/timers:569:17)
    at process.processTimers (node:internal/timers:512:7)

Node.js v18.19.0

user@orangepipc:~/wakeword$ cat /etc/issue

user@orangepipc:~/wakeword$ uname -an

any ideas?
