@Kevin Kho Your example snippet above worked out perfectly fine, thank you for that! I’m kinda stuck with the next thing though: I don’t want to use a hard coded list of dates as shown in the snippet, but a task that creates the list using the given flow parameter, something like this:

with Flow('Parent Flow') as flow:
    year = Parameter('year')
    dates = create_dates_list(year) // still a list of dates, but this is now a task.

    child_flows = []
    for i in range(len(dates)):
       x = create_flow_run(...)
       child_flows.append(x)
    for i in range(1,len(dates)):
       child_flows[i].set_upsteam(child_flows[i-1])

When I try that it throws the error

len(dates): FunctionTask doesn't have the attribute len

. Is there a way to get the value of the task instead of the reference to the task instance? Something else I’ve tried: making the task

create_dates_list

a regular python function, so just removing the task decorator. But then it throws an error because the function’s argument value looks like

<Parameter year>

, so it’s the parameter instance and not the value of the Parameter. Is there a way to get the value of a Parameter inside a function that is not a task? I hope this makes sense! 🙏
