Api-platform - Virtual property - Collection denormalization - php

Question

I have Reservation entity, which contains some ReservationRev(isions) collection. ReservationRev contains PersonStay collection.
In Reservation I have virtual property personStays (getter, add, remove, setter).
When I try to POST Reservation with personStays I get an error - denormalizer for Collection can't be found.
class Reservation
