Thomas CysCopied from ProductionVariation class baseFieldDefinitions method:
// The price is not required because it's not guaranteed to be used
// for storage (there might be a price per currency, role, country, etc).
I accidentally forgot to add to price and ran into this issue but are there use cases where you don't want to add a price to a product? If there are the price should be 0 not null imo.
