Can't run scripts

[Elmente85]

Hello, currently I am running HA Bridge through a Docker Container on LibreElec on a Raspberry PI. I am using the Raspberry to control an Ambilight clone for my television. A year ago everything went fine, and I had all the things working, but a few days ago the SD card crashed, and everything is gone now :((

At the moment, I am trying to get HA Bridge working again, but I can't get any scripts running. For testing purposes I have made a script called "test.sh" and placed it under "/storage/downloads/habridge".

Content of "test.sh":
#!/bin/bash
mkdir /storage/downloads/habridge/test

If I call that script using Putty from my PC everything works fine (see Screenshot below):

I am now trying to execute this script using HA Bridge, but i don't get it working again (see configuration below):

If I click on "TEST ON" i get the green message "Request Executed" but nothing happens :-(

Can you maybe help me get it working again, please?

Thanks in advance.
