Bug report

Describe the bug

I am following recipe of Digital Products here: https://docs.medusajs.com/v2/resources/recipes/digital-products/examples/standard. I created a Shipping Option and I have put 0 price (as delivery of digital product is free). Unfortunately, it causes error on checkout:

error:   Shipping options with IDs so_01J5B1TNKMHCXFCS41DTM1JCZX do not have a price
