Is there a way to get final urls for each keyword from api

Hi All,

I recently met an issue with final urls, I tried to get final urls for each keyword but it always return null for some reason, could you please help me with this issue ? Thanks a lot.

public class FinalUrls {

    private static final int PAGE_SIZE = 100;

    public static void main(String[] args) throws Exception {
        // Generate a refreshable OAuth2 credential.
        Credential oAuth2Credential = new OfflineCredentials.Builder()
                .forApi(OfflineCredentials.Api.ADWORDS)
                .fromFile()
                .build()
                .generateCredential();

        // Construct an AdWordsSession.
        AdWordsSession session = new AdWordsSession.Builder()
                .fromFile()
                .withOAuth2Credential(oAuth2Credential)
                .build();

        Long adGroupId = Long.parseLong("3310344562");

        AdWordsServices adWordsServices = new AdWordsServices();

        getFinalUrls(adWordsServices, session, adGroupId);
    }

    public static void getFinalUrls(AdWordsServices adWordsServices, AdWordsSession session, Long adGroupId) throws Exception {

        int offset = 0;

        // Get the AdGroupCriterionService.
        AdGroupCriterionServiceInterface adGroupCriterionService =
                adWordsServices.get(session, AdGroupCriterionServiceInterface.class);

        SelectorBuilder builder = new SelectorBuilder();
        Selector selector = builder
                .fields(
                        AdGroupCriterionField.Id,
                        AdGroupCriterionField.CriteriaType,
                        AdGroupCriterionField.KeywordMatchType,
                        AdGroupCriterionField.KeywordText,
                        AdGroupCriterionField.FinalUrls)
                .orderAscBy(AdGroupCriterionField.KeywordText)
                .offset(offset)
                .limit(PAGE_SIZE)
                .in(AdGroupCriterionField.AdGroupId, adGroupId.toString())
                .in(AdGroupCriterionField.CriteriaType, "KEYWORD")
                .build();

        AdGroupCriterionPage page = adGroupCriterionService.get(selector);

        // Display ad group criteria.
        if (page.getEntries() != null && page.getEntries().length > 0) {
            // Display results.
            for (AdGroupCriterion adGroupCriterionResult : page.getEntries()) {
                Keyword keyword = (Keyword) adGroupCriterionResult.getCriterion();
                System.out.printf(
                        "Keyword with text '%s', match type '%s', criteria type '%s', and ID %d was found.%n",
                        keyword.getText(), keyword.getMatchType(), keyword.getType(), keyword.getId());
                BiddableAdGroupCriterion biddableAdGroupCriterion= (BiddableAdGroupCriterion) adGroupCriterionResult;
                System.out.printf("Keyword final url is %s", bac.getBidModifier());
                if (biddableAdGroupCriterion == null) {
                    System.out.println("object is null");
                } else {
                    System.out.printf("Keyword final url is %s", biddableAdGroupCriterion.getFinalUrls().getUrls(0));
                    System.out.println();
                }
            }
        } else {
            System.out.println("No ad group criteria were found.");
        }

        offset += PAGE_SIZE;
        selector = builder.increaseOffsetBy(PAGE_SIZE).build();
    }
}
