Stripe: Update Subscription Item "Plan" Parameter should be optional

I’m trying to update the quantity of an existing subscription item to zero when a user cancels service, but because the “Plan” parameter is not optional, Stripe thinks I’m trying to change the plan, and is throwing an error when I attempt to set the quantity to zero. I could delete the subscription item, but I’d like to keep it in case a user reactivates service. @emmanuel , is this an easy fix you guys could make, or should I find a workaround? Thanks.

I can confirm that making the API call without the Plan parameter allows setting the quantity to 0 without error, so I’ll use that for now.
