I think Factorio accepts recipe results without the type field in that structure, and if it's missing, assumes it is zero.
Further, if the type field is absent, Factorio does not insist on the 'name' or 'amount' labels being present either. In this case it assumes that the table row is in 'name', 'amount' order.

The base game recipes follow this format strictly, but the vanilla code seems to allow the 'type' to be missing.

Am I right?

if product or ingredient type are missing, is equal 0 or item

That what it seems like, but the specification at the link I gave does not say that 'type' is optional, nor do any of the examples exclude it. It says that only amount, amount_min, amount_max and probability are optional.
