Problem using advanced features of shell plugin on Ubuntu server

[SprickW]

Summary

After fiddling around with tipps given in the wiki but finally not being successful I started from scratch.

My intent:

In a VM (not LXC) running Ubuntu 22.04 minimal server a regular user shall prepare and test scripts, that later shall bei executed bei Cronicle on a regular basis.

For this I cloned the shell plugin and used the advanced options and specified "Working Direktory (CWD)" and "Run as User (UID)" as home directory and uid of the intended regular user. I considered this as a feature offered by the advanced options.

When running a simple "whoami" I receive

Error: Child spawn error: bin/shell-plugin.js: Child process failed to spawn (Check executable location and permissions?)

In the docs I only found "Cronicle spawns a sub-process for each job, executes a command-line you specify, ..." but no further hints on how to use the advanced features of the shell plugin.

As "whoamin" should not cause excecution and permission problems I need further assistance.

Leaving "Working Direktory (CWD)" empty causes "whoami" to work properly.

But then trying to run a script installed by the user fails with "not found".

Steps to reproduce the problem

• with working directory and uid
• with only uid

Stupid me:

export PATH=$PATH:/home/maddev/.local/bin

solved the problem not finding the executable.

Which leaves the issues with what "Working Direktory (CWD)" is meant for.
