Hello everyone.. trying to set a launchplan with scheduler but get an error that can’t understand. This is the workflow and launchplan. The workflow works correctly, the problem is with the launchplan registration

import typing
from flytekit import workflow, LaunchPlan, CronSchedule
from sync_historicals import check_people


@workflow
def sync_historicals_workflow() -> typing.List[str]:
    return check_people()



lp = LaunchPlan.get_or_create(
    "sync_entityes_workflow_scheduler",
    sync_historicals_workflow,
    schedule=CronSchedule(
        schedule="*/15 * * * *",  # Following schedule runs every min
    ),
)

and this is the error at registration

Any ideas?

which version of flytekit are you using?

lp = LaunchPlan.get_or_create(
    "sync_entityes_workflow_scheduler",
    sync_historicals_workflow,
    schedule=CronSchedule(
        schedule="*/15 * * * *",  # Following schedule runs every min
    ),
)

Can you use named args instead of positional args. I wonder if ordering of args changed...

lp = LaunchPlan.get_or_create(
    name="sync_entityes_workflow_scheduler",
    workflow=sync_historicals_workflow,
    schedule=CronSchedule(
        schedule="*/15 * * * *",  # Following schedule runs every min
    ),
)

using named args was the solution
