Hello all, I have what I think is a simple question: I have a flow that creates a container, waits on the container, and then gets the container logs. How can I have it throw an error and bail out on things if the WaitOnContainer has a failure in it? I have a slack notifier set up to only output failure, but it is not notifying upon failure of WaitonContainer. Flow code for reference in the thread

`start = StartContainer()`
l`ogs = GetContainerLogs(trigger=always_run)`
`status_code = WaitOnContainer()`

`## set task dependencies via functional API`

`with Flow(name="ispottv",`
          `state_handlers=[slack_notifier],`
          `) as flow:`
    `start_container = start(container_id=container)`
    `code = status_code(container_id=container, upstream_tasks=[start_container])`
    `collect_logs = logs(container_id=container, upstream_tasks=[code])`

Can you write a task to parse the logs for the fail message? And then use a `signals`?
