Endpoint not supported for cover type

[dominicusmento]

What happened

Trying to use a converter for 2ch zigbee module but can't start zigbee2mqtt with it defined in configuration.

What did you expect to happen

Add the external converter into the config and use the device which supports to control two separate covers and therefore it has multiple zigbee endpoints

How to reproduce it (minimal and precise)

Add the converter from #8705 (comment) to the configuration and restart the zigbee2mqtt

Debug info

Zigbee2MQTT version: 1.21.1-1
Adapter hardware: CC2531
Adapter firmware version: -

Error

If I've traced correctly, problem should be in this file: https://github.com/Koenkk/zigbee2mqtt/blob/master/lib/extension/homeassistant.js

Should be fixed now, can you check?

Changes will be available in the dev branch in a few hours from now. (https://www.zigbee2mqtt.io/how_tos/how-to-switch-to-dev-branch.html)

Seems fine now regarding this issue, tested with zb2mqtt edge.
Starts fine, pairing successful; device itself has some problems but this issue is solved. Thank you very much 😊
