java.lang.NullPointerException (ModelMapper.java:150) (Instagram.java:159)

[GiorgosXou]

First of all thanks you for developing this library, second of all I am really confused trying to make it work (as a kinda noobie that i am), (pls make another release so we can use it with maven [because jitpack with master-SNAPSHOT doesnt work for me at least now that i am posting this issue])

[General] :

App.java

package app;

import me.postaddict.instagram.scraper.interceptor.ErrorInterceptor;
import me.postaddict.instagram.scraper.cookie.DefaultCookieJar;
import me.postaddict.instagram.scraper.interceptor.UserAgents;
import me.postaddict.instagram.scraper.cookie.CookieHashSet;
import me.postaddict.instagram.scraper.AuthenticatedInsta;
import me.postaddict.instagram.scraper.model.Account;
import me.postaddict.instagram.scraper.interceptor.*;
import me.postaddict.instagram.scraper.Instagram;
import okhttp3.logging.HttpLoggingInterceptor;
import okhttp3.OkHttpClient;


public final class App {
    private App() {}
    
    private static AuthenticatedInsta client;

    public static void main(String[] args) throws Exception {
    
        Credentials credentials = new Credentials() ;
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        
       loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.HEADERS);

        OkHttpClient httpClient = new OkHttpClient.Builder()
                .addNetworkInterceptor(loggingInterceptor)
                .addInterceptor(new FakeBrowserInterceptor(UserAgents.WIN10_CHROME))
                .addInterceptor(new ErrorInterceptor())
                .cookieJar(new DefaultCookieJar(new CookieHashSet()))
                .build();

        client = new Instagram(httpClient);
        client.basePage();
        client.login(credentials.getLogin(), credentials.getPassword());
        client.basePage();

        Account account = client.getAccountByUsername("giorgos.xou"); // Issue.
        //System.out.println(account);
    }
}

Then Suddenly:

Exception in thread "main" java.lang.NullPointerException
        at me.postaddict.instagram.scraper.mapper.ModelMapper.mapAccount(ModelMapper.java:150)
        at me.postaddict.instagram.scraper.Instagram.getAccountByUsername(Instagram.java:159)
        at app.App.main(App.java:44)

Any Idea? Thanks in advance.
