RestAssured, POJO and dealing with lists

Question

I'm writing a test for an API and at one endpoint I get JOSN in response with couple arrays into one array. Can I make POJO class which mapping those array/arrays into a class object?

for example, JSON in response looks like this:

{
"total": 55,
"limit": 500,
"skip": 0,
"data": [
    {
        "id": 13,
        "email": "probe@gmail.com",
        "phone": "121-121-123",
        "firstName": "Prob",
        "lastName": "Buraz",
        "platforms": [
            {
                "id": 3,
                "name": "Dowe Assis",
                "url": "ins.probe.com",
                "user_platforms": {
                    "id": 496,
                    "userId": 13,
                    "platformId": 100,
                    "user_id": 82
                }
            }
        ], .....

And so on. I suppose that I can use this class for mapping response into POJO:

 @JsonIgnoreProperties(ignoreUnknown = true) 
public class GetUsers {

public  Integer total;

public Integer limit;

public List<DataReference> data;   
@JsonIgnoreProperties(ignoreUnknown = true)
public static class DataReference{              
    public int id;
    public String email;
    public String phone;
    public String firstName;
    public String lastName;


public List<Platform> platforms;                    
@JsonIgnoreProperties(ignoreUnknown = true)             
public static class Platform{
    public Integer id;
    public String name;
    public String url;
}   

}

}

But in the test code i can get nothing more then data elements. platforms elements are untouchable:

 GetUsers users = given()
          .header("Authorization",              
                  "Bearer " + adminToken)        //
          .when()
          .get()
          .then()//.log().all()
          .statusCode(200)//.log().all()
          .extract().as(GetUsers.class);

i can checks values of array data like those:

 assertThat(users.data).extracting(user -> user.email).contains("probe1@gmail.com", probe+2@gmail.com, ... );

But i can't access to any value of users.data.platforms.name or users.data.platforms.id and so on.

How I can access to platform element for one of users?

users.data.platforms.name

How i can do that (access platforms data) for one or for all listed users in data array?

Which library you are using for JSON POJO mapping? If there is no error with mapping then platform variable can be accessed using following.

Add getter setter in POJO

users.getData.getindex(0).getplatforms.getindex(0).getid();

users is object of GetUsers Class which is used to map the JSON response.
