Can't read the env var I set in my python code

Question

    """Get a required environment variable or raise RuntimeError if not set."""
    value = os.environ.get(name)
    if not value:
        raise RuntimeError(f"{name} not configured!")
    return valueMY_ENV = get_required_env("MY_ENV")Redeply/Restart not helping
