Home Assistant Add-on 0.0.29 fails to build on amd64: BUILD_FROM is empty

[andischlank-sudo]

Hello,

I am unable to install Noah-MQTT add-on version 0.0.29 on Home Assistant OS.

Environment:

• Home Assistant OS: 17.3
• Home Assistant Core: 2026.6.1
• Supervisor: 2026.05.1
• Architecture: amd64
• Hardware: Lenovo ThinkStation

Installation fails during Docker build with the following error:

Docker build failed for ed203dbf/amd64-addon-noah_mqtt:0.0.29

#0 building with "default" instance using docker driver
#1 [internal] load build definition from Dockerfile
#1 transferring dockerfile: 690B done
#1 WARN: InvalidDefaultArgInFrom: Default value for ARG $BUILD_FROM results in empty or invalid base image name (line 2)
#1 DONE 0.0s

Dockerfile:

ARG BUILD_FROM
FROM $BUILD_FROM

The build stops before the application starts.

Repository:
https://github.com/mtrossbach/hassio-addons

Could you please check whether there is an issue with the add-on build configuration for Home Assistant OS 17.3 / Supervisor 2026.05.1?

Thank you.
