[Error] cannot deserialize from Object value (no delegate- or property-based Creator)

@Getter 
@Setter
public class From {
    private MultipartFile attachFile;
    
    // 빈 생성자 추가
    public From() {
    }

    public From(MultipartFile attachFile) {
        this.attachFile = attachFile;
    }
}

• 빈 생성자 추가하면 해결
