Hello everyone Looking for suggestion on debugging under VSCODE.

Copy code

import debugpy
debugpy.listen(("localhost", 5678))
print("Waiting for debugger attach...")
debugpy.wait_for_client()  # Only include this line if you want the script to pause until the debugger is attached.
print("Debugger attached."

set up the configuration and attached. Breakpoints are skipped and I see

pulumi:pulumi:Stack (app-dev):

0.00s - Debugger warning: It seems that frozen modules are being used, which may

0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off

0.00s - to python to disable frozen modules.

0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.

asked ChatGPT for suggestion with Pulumi and it hallucinated the --exec option. which aparently does not exist..

Copy code

PYTHONPATH=$(python -c "import sys; print(':'.join(sys.path))") pulumi up --exec "python -Xfrozen_modules=off __main__.py"

Any pointers ?? thank you

I don't think there's currently a way to pass extra options to python. For nodejs there's the

nodeargs

option https://www.pulumi.com/docs/concepts/projects/project-file/#runtime-options Consider creating a feature request on https://github.com/pulumi/pulumi to get something similar added for python.

This is my VSCode configuration for running Pulumi in debug mode. The launch task sets the env variable

PULUMI_DEBUG=true

and the Python entrypoint uses that to determine whether to start a debugpy session. I include this conditional check in all my Pulumi entrypoints as it won't interrupt operations when I don't want debug mode. Native VScode (UI) breakpoints are working 99% of the time but in some rare cases I've had to explicitly insert a

debugpy.breakpoint()

line where I want the debugger to break.

Thanks Olafur. The issue was the main.py being in a subfolder with incorrect localRoot. Once corrected as below , it steps through like a champ

Copy code

"pathMappings": [
                {
                    "localRoot": "${workspaceFolder}/awsx",
                    "remoteRoot": "."
                }
