2.5: slot_program returned non-zero exit status 127

I used a slot_program which was working fine before 2.5 pre-release.
Now I get

rhasspyserver_hermes: Command '['/profiles/de/slot_programs/devices']' returned non-zero exit status 127.
Traceback (most recent call last):

The program:

#!/usr/bin/env bash
curl -s 'http://<url>' | jq -r -f <path>/getDevicesFilter.txt

This lists devices defined in my home automation software. Every device in an extra line. Like:

TV
Computer
Ceilinglight

Any idea what has changed with 2.5?

@schnopsi just had the same error / problem. keep in mind, that if you use the docker installation, the script will run within that docker container. and maybe there was no jq installed there.
(it is in version 2.5.8)
