Question - How to obtain the working folder from with a script?

[DylanFromEdwards]

I have a .sh script executing, but I get an error:

"stepResults":{"step_0":{"resultCode":0,"extendedResultCodes":"30500205","resultDetails":"The install script doesn't create a result file '/var/lib/adu/downloads/7aebbd16-70df-4b74-8cce-39aceb13a66f/action_download_aduc_result.json'."

I've created a action_download_aduc_result.json file, but assume it needs to be stored in the correct folder. I assume it's the working folder or Sandbox folder?

Property '_workFolder' not NULL - returning cached workfolder '/var/lib/adu/downloads/7aebbd16-70df-4b74-8cce-39aceb13a66f'
Setting sandbox /var/lib/adu/downloads/7aebbd16-70df-4b74-8cce-39aceb13a66f [SandboxCreate:391]

The question is how do I reference this from within a script?

Copilot suggests using and environment folder, along the lines of...

sandbox_dir=$ADUC_SANDBOX_DIR

This gives an empty string within the script and the file gets written to /

The example https://github.com/Azure/iot-hub-device-update/blob/develop/src/extensions/step_handlers/script_handler/examples/example-installscript.sh expects an argument to be passed, but I can't find an example of the argument.

Could someone tell me how I get the working/sand folder in the script? Or where the result file should be written.

The documentation I was following is here...

I've also been trawling for examples from various places.

Is the Microsoft Learn platform for this project live? Could I have a link, if so.
