Environment: ChatGPT Plus, Web, Windows 11, Chrome.
Issue: Python/container execution repeatedly fails with:
ClientError
Encountered exception: <class 'caas.internal.errors.ClientError'>
The failure also occurs with trivial commands that do not access user files, so it does not appear to depend on a specific uploaded file.
Expected: Python/container should execute normally.
Actual: Execution fails immediately with ClientError.

I am intentionally not attaching private files or project contents. I am only reporting the reproducible runtime error.
