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

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 ?
