Serialisation & POJOs — quiz

You pass `User user = new User("Ada", 30);` to `.body(user)`. The request goes out as `{}`. What's the most likely cause?

• Rest Assured can't serialise POJOs
• Jackson can't see the fields — they're `private` with no getters/setters and no Lombok. Either expose them via getters/setters (Jackson's default discovery), annotate with `@JsonProperty`, or configure Jackson's visibility
• POJO fields must be `public static`
• JSON requires fields to be Strings
