Error executing vcgencmd with package node-red-contrib-vcgencmd #55

I'm running the project on my Pi4 and installed the node-red package node-red-contrib-vcgencmd in order to access the Pi's temperature measure. The installation was successful and the nodes are available:

Additionally the container requires the apk package raspberrypi to be installed via: apk add --no-cache raspberrypi

and the compose file amended with

    devices:
      - /dev/vchiq:/dev/vchiq

However, an error is raised in the debug messages : Error executing /opt/vc/bin/vcgencmd : Error: Command failed: /opt/vc/bin/vcgencmd measure_temp

With the base images nodered/node-red (node 10) and nodered/node-red:latest-12 it works out of the box. FROM nodered/node-red or FROM nodered/node-red:latest-12

Do you have any ideas why this is happening ? Any special setup of the ghcr.io/ct-open-source/ctnodered:latest image which prevent vcgencmd to be executed correctly ?
