Looks like the exception is caused by ElectricGoldPan, ElectricDustWasher, and OilPump. These machines use sort of a "hack" where the recipes they use have no input but consume an item anyway.

Oh damn, almost pushed the fix but you beat me to it 😄

Just realized... What about the dust washer and oil pump? 😄
