I added a metafield synced field on the shopifyProductVariant data model, and it shows "Namespace is not registered on 1 shop" with a button "Register Namesapce". So I click on the button, and it ends up removing all registered webhooks from shopify (I verify this by checking on the install page and it shows 20 webhooks missing). Its like a dance, either the metafields, or all the webhooks.
