lower bounds: java.util.List<model.Car>,java.lang.Object

Mam taki blad:
incompatible types: inference variable R has incompatible bounds
[ERROR] equality constraints: java.util.Set<T>
[ERROR] lower bounds: java.util.List<org.openapitools.model.Car>,java.lang.Object

Wykonuje taki kod:
Mapuje Set<Car> na Set<Car>
Obiekty A i B sa enumami.

editDto.getCars().stream()
                    .map(Car -> com.domain.Car.findByCar((Car.getValue())))
                    .collect(Collectors.toSet()));
