Help needed to install an External Converter in Zigbee2mqtt

I recently moved from ZHA to Z2M to get a device up and running.
But I doesn’t get it to work and would really appreciate some help.
When I try to Submit the converter in Z2M UI I get an error message, and I can’t find anything about this.
Z2M error message:

Request ‘zigbee2mqtt/bridge/request/options’ failed with error: ‘external_converters must be array’

The converter:

HA 2024.6.3
Zigbee2MQTT addon 1.38.0-1
ZB Adapter, SLZB-06P7 (LAN connection)
Mosquitto brokerCurrent version: 6.4.1

I have tried to add this rows in both configuration.yaml and in Z2M Add-on Settings.
No difference, same error every time when I try to Submit the converter in Z2M UI.

external_converters:
  - amina_s.js

configuration.yaml from folder

I have the same problem.

can you solve the problem? I have the same problem.

Had the same issue after updating Z2M to 1.38.0-1.
Restored version 1.37.1-1 and problem disappeared.

Replace your value with “empty” like this

external_converters:
  - empty

Problem solved!
Got some help in Z2M Discord channel.

They think it is something wrong in Z2M UI.

But the documentation for install an external converter is also wrong.
It should be installed in UI (when it is fixed) OR in configuration.yaml - Not both.
