Hi, my state of my flow is set as successful even though task fail. I am not sure why this happens. I have a parent flow which create and runs multiple child flows. A task in a child flow fails but the child flow is marked as successful so other downstream child flows run when they shouldn't. Each child flow (1-5) has a create_flow_run and wait_for_flow_run(). Child flow 2 and 5 wait_for_flow_run() have been set has reference task so the parent flow is successful if they both complete. A task fails in child flow 3 but the flow is marked as successful

Can you move the code block and the image in the posts below to this thread to keep the main channel cleaner? There is one flag on the

wait_for_flow_run

task that you need to set to raise Failure in the parent flow upon a failure in a child flow:

raise_final_state=True

Here is an example in a flow:

from prefect import Flow
from prefect.tasks.prefect import create_flow_run, wait_for_flow_run

with Flow("parent_flow") as flow:
    child_flow_run_id = create_flow_run(
        flow_name="child_flow_name", run_name="custom_run_name"
    )
    child_flowrunview = wait_for_flow_run(
        child_flow_run_id, raise_final_state=True, stream_logs=True
    )

Thanks Anna, Cleaned up the main thread, actually though I was placing those with this thread, lol

Can you share your flow in that case? This flag was introduced in 0.15.8 so this should work, unless your agent or execution environment uses an older Prefect version
