adding external convertors prevents z2m to start

[rgrs83]

Hi all,

I am trying to install an unknown (tuya) device using an external converter. I followed these guides:
https://www.zigbee2mqtt.io/advanced/support-new-devices/01_support_new_devices.html#_1-pairing-the-device-with-zigbee2mqtt

and this one
https://www.zigbee2mqtt.io/advanced/support-new-devices/02_support_new_tuya_devices.html#instructions

My main issue at the moment is, that when I add this:

external_converters:
  - mydevice.js

to the configuration.yaml, z2m fails to start.
Z2M version: 1.25.2 commit: 9b2a921

Configuration.yaml:

homeassistant: true
permit_join: true
external_converters:
 - mydevice.js
