I'm just getting to adding a schedule to my first Flyte workflow and I have a few questions. My workflow takes two arguments, a datetime and an int.

@workflow
def cohort_ltv_inference(inference_date: datetime, n_days_horizon: int) -> bool:
    ...

I had created a schedule in my launch plan but failed to provide

kickoff_time_input_arg

or

default_inputs

.

launch_plan = LaunchPlan.get_or_create(
    name="pir_cohort_ltv_inference",
    workflow=cohort_ltv_inference,
    schedule=CronSchedule(
        schedule="45 17 * * *",  # At 17:45 daily.
    ),
)

In the workflow web ui, I see the schedule displayed:

Schedules
At 05:45 PM

But when I noticed that no scheduled run was actually happening, I looked through the scheduler logs and saw messages like this:

rpc error: code = InvalidArgument desc = expected_inputs inference_date missing

Ideally the end user would be alerted about this earlier. I saw a related issue on github here, and a PR here. I haven't worked in Go, but I think the function

validateLaunchSpec

doesn't handle the case of no

default_inputs

and no

fixed_inputs

passed to the launch plan

get_or_create

. In general I'm missing some of the familiar scheduler UI I am used to from my experience with Airflow. I know these are very different projects, but for almost all my use cases, I'll eventually be running the ML pipeline on a schedule.

Thanks @fancy-yak-23698 for reporting these . Fixed them here https://github.com/flyteorg/flytectl/pull/368 https://github.com/flyteorg/flyteadmin/pull/494

Wow @icy-agent-73298! You fixed the issues before I even had time to get back to this slack thread! I'll chat with with some of my colleagues as we are all making the shift from Airflow to Flyte for ML workflows. And I'll create a Jira issue.
