My app edits order to add more items. There is an order giving me an error of variantRequiresSellingPlan, the message is “This variant requires a selling plan to be specified.”. What does it mean? The order edit process was stopped due to this error.
My app doesn’t handle subscriptions. Why is a selling plan required? I could only find
which says you set a product to be sold only as a subscription, does this mean it can’t be added in a regular order.
