hi, I'm on prefect 1 using this pattern to pass a task's result from a child flow to a parent flow: https://discourse.prefect.io/t/how-to-pass-data-from-a-child-flow-to-another-task-in-a-parent-flow/126 the child flow is mapped with

create_flow_run.map

. How to get the results of the mapped flow? I'm getting this error:

└── 09:11:14 | ERROR   | Task 'get_task_run_result': Exception encountered during task execution!

Thank you for sharing your solution here, Jon!
