Failed to find pip3 during addon start rPi Zero W

Hi, i have reinstalled HA and now all python addons fails to start with following log:

[s6-init] making user provided files available at /var/run/s6/etc...exited 0.
[s6-init] ensuring user provided files have correct perms...exited 0.
[fix-attrs.d] applying ownership & permissions fixes...
[fix-attrs.d] done.
[cont-init.d] executing container initialization scripts...
[cont-init.d] done.
[services.d] starting services
[services.d] done.
Run.sh starting

/run.sh: line 13: pip3: command not found
[cmd] /run.sh exited 127
[cont-finish.d] executing container finish scripts...
[cont-finish.d] done.
[s6-finish] waiting for services.
[s6-finish] sending all processes the TERM signal.

run.sh contains:

echo "Installing requirements"
pip3 install -r requirements.txt

and docker:

# Install requirements for add-on
RUN apk add --no-cache --update python3 jq

Is it something wrong on my side or the rPI zero W is no longer supported?
Thanks for any advice.
