Hi All, since i havent find solid info about custom parameters in step-functions deployment. I would like to ask it here.

I have a flow where there is a custom parameter called `number_of_items` . I need to deploy this onto step functions. So, i use `python path_to_metaflow.py --with batch:image=image:latest --branch sk --production step-functions create --number_of_items 15'`  which gives me an error.

So, cant we supply custom parameters during step function deployment?

thx in advance.

I believe this is not possible. You can use default parameters to do this, see also <https://docs.metaflow.org/production/scheduling-metaflow-flows/scheduling-with-aws-step-functions#deploy-time-parameters>.

I am also just a user of metaflow myself, but I think the reason is that at deploy time you do not manually want to set some parameter. Instead you want to do this by setting a default parameter, which could be set specifically for deploy time using a default function. as in the link. In this way deployment is not depending on manual input.

thanks mate. it makes sense the info on the link.
