Pairs with getPriceInfoObjectId: Hermes is queried by feed id and the Move call takes the object, so the two must come from the same deployment or the update lands on an object the on-chain feed-id check then rejects.
The PriceInfoObject id for a coin on Pyth's upgraded Core.
Throws rather than passing undefined into a move call: a feed may simply have no
object on the upgraded deployment yet, and the resulting on-chain abort
(EPriceFeedIdMismatch) does not say which coin was at fault.
