CMK version: 2.1.0-2022.04.13 CRE (Docker check-mk-raw)
Error message:
N/A
Description of the issue
I have the bash script testbash.sh with the following content:
#!/bin/bash
echo "0 \"testbash\" - Just a test"
and the python script testpython.sh with the following content:
#!/usr/bin/env python3
print("0 \"testpython\" - Just a test")
On my terminal I can see the following information:

According to my understanding check_mk_agent provide the right output from both plugins but for some reason cmk can only detect the bash plugin. On the GUI service discovery I can also only see the “testbash” service and NOT the “testpython” service.
Why it can’t detect it?
