Running Python Code as a Supporting Task

[matt-rx]

Hi, I’m trying to run a Python code as a supporting task. I’ve created a bat file that contains 

@Echo off
"C:\Program Files (x86)\python.exe" "D:\QV\Data\python_code.py"

I provide it as a parameter in the supporting task. However, after reloading, it returns: 

(27.03.2025 14:58:57) Information: Executing "D:\QV\Scripts\run_python.bat"

(27.03.2025 14:58:57) Information: Executing commandline: "D:\QV\Scripts\run_python.bat" in folder "D:\QV\Scripts".

(27.03.2025 14:58:58) Error: The process exited with non-zero ExitCode (1) at 27.03.2025 14:58:58

(27.03.2025 14:58:58) Error: The task "run_python.bat" failed. Exception: || QDSMain.Exceptions.TaskFailedException: The process exited with non-zero ExitCode (1) at 27.03.2025 14:58:58 || at QDSMain.ExternalProgramTask.Execute(IExecutingTaskResult executingTaskResult) || at QDSMain.Task.AbstractTask.TaskExecution(CurrentExecutionArgs args)

Parameters
Command line statement:"D:\QV\Scripts\run_python.bat"

It seems like the python script was called, but that the python script ended with an error. I'd start investigating the python script rather than the execution trigger in qlik.

The script run by the bat file is being processed; at the beginning, it only shows a message about running the 32-bit Python on a 64-bit server. I'll check the version change when I have some free time.

The problem is solved. The Qlik user on the server couldn't see the Python package 'paramiko'. When I added traceback exception logging, I was able to identify the issue.
