Hey - I have a flow that has a few clocks eg

au_harness_win_place = CronClock(
    cron="33 * * * *",
    parameter_defaults={
        "race_types": ["Harness"],
        "market_type_codes": ["WIN", "PLACE"],
        "event_type_ids": None,
        "market_countries": ["AU"],
        "table_name": "harness_market_catalogue_au"
    },
    start_date=datetime.now(tz=timezone("Australia/Brisbane")),
)

that is called like so

with Flow(
    name="betfair_market_catalogues",
    storage=Storage.in_a_s3_bucket(),
    run_config=RunConfig().fargate_on_ecs(),
    schedule=Schedule(clocks=[au_nz_greys_win_place, au_harness_win_place]),
    executor=LocalDaskExecutor(scheduler="threads"),
) as flow:

If I want to call this via the cli it doesnt like the None values and the python objects, do I have to accept stringified versions of this or does prefect handle this on its own? eg, how would I run this locally

prefect run -p flows/market_catalogues/betfair_market_catalogues.py --param table_name="harness_market_catalogue_au" --param race_types=["Harness"] --param market_type_codes=["WIN", "PLACE"] --param event_type_ids=[] --param market_countries=["AU"]

doesnt do the job

I think you need to accept stringified versions as the params from CLI just come in JSON so you can’t have native Python types.

ah right, so I can just wrap

json.dumps

around them

You mean json.loads?

I mean for the

parameter_defaults=

I don’t think you need to became we handle that you register. Your problem is just an ad-hoc run with the CLI right?

yes - ad hoc run

I think you can if you do:

with Flow(..) as flow:
    ...

if __name__ == "__main__":
    flow.run(parameters={..})

and then you can call the register using the CLI but use the main section for ad hoc runs?

ah ok

run_on_schedule=False maybe

thats the one
