Hello! I'm trying to create a flow of flows in which some child flows depend on others. When trying to make 2 of them run sequentially using the following code snippet,

wait_for_flow_run

fails by throwing

TypeError: Object of type FlowRunView is not JSON serializable

. Am I passing the wrong object type as input?

from prefect.tasks.prefect import create_flow_run, wait_for_flow_run

with Flow("run-pipeline") as flow:
    flow_a_id = create_flow_run(flow_name=flow_a.name, ...[SOME INPUT PARAMS])
    flow_a_wait = wait_for_flow_run(flow_a_id)

(I'm using prefect 1.0.0)

Hi ! Are you sure the

children

param of

Flow

exists ? I can't see it anywhere on the API docs.

Hey! You're right, that's an input parameter to a wrapper I built on top of the regular flow, but it's irrelevant for the issue as it just assigns an instance variable. (I edited the original question).

it should normally be a name of an already registered flow, check this post for an example https://www.prefect.io/guide/blog/flow-of-flows-orchestrating-elt-with-prefect-and-dbt/
