Pycharm remote debugger is stuck on waiting for connection when running from Pycharm `Cloud Code: Kubernetes` run configuration
I'm trying to run in debug mode, a Python FastAPI application running in a container using PyCharm's Cloud Code plugin, but I can't get breakpoints to work.
Setup:
- PyCharm with Cloud Code plugin
- Python 3.11 FastAPI application using base docker image from
tiangolo/uvicorn-gunicorn-fastapi:python3.11 - docker-desktop local deployment via
Cloud Code: Kubernetesrun configuration
What happens:
- The container deploys successfully
- Port forwarding works (both for app and debug ports)
- The application runs normally
- Breakpoints are never hit - I see a background task on debugger which says "waiting for connection"

Logs show this warning (not sure if relevant):
[elon] WARN[0000] not a python launcher: unable to determine python version from "/usr/bin/env": exit status 125
From container inspection:
$ kubectl exec -it pod-name -- ps -ef

The container can successfully reach my host machine:
