I'm getting this error once I try to edit an entry that has the field attached to it. Could it be it's related to my Shopify account being still in Demo mode? I can though fetch data using storefront API. <img width="1360" alt="error" src="https://user-images.githubusercontent.com/422124/120033253-a328f900-bffb-11eb-9384-e242e69a5376.png">
