help with exception handling

[maximqqe]

I'm trying to handle ConnectionTimeout exception in python SDK, I saw that the request is sent after the function is executed, with flush_at, so try except won't work. What are the ways to catch this exception?

    with langfuse.start_as_current_observation(name="test") as span:
        some_func()

        try:
            span.end()
            langfuse.flush()
        except Exception:
            logger.error("\n\nLANGFUSE CONNECTION FAILED\n\n")
