Stripe No Such Price Error

I kept experiencing a “No such price” error when attempting to modify a price on behalf of a Stripe connected account.

Turns out that I wasn’t calling modify() with the connected account id, which results in Stripe looking for the price in the platform’s account.  

To modify the price for a connected account, do so like this:

existing_price_change = stripe.Price.modify(
stripe_price_id,
active=False,
stripe_account=stripe_account
)

The last parameter, stripe_account=stripe_account, should be the ID for the connected account. Including it sets the correct HTTP header when sent to Stripe.
