I'm trying to get google firebase dynamic link work on my .net core project my code is as below

public static async Task<string> GetShortLink(string longLink)

{

    var service = AuthenticateServiceAccount("gayan@empite.com", "Opt/Keys/quallogi-keys.json", new { "https://www.googleapis.com/auth/firebase" });

    var request = service.ManagedShortLinks.Create(new CreateManagedShortLinkRequest

    {

        DynamicLinkInfo = new DynamicLinkInfo

        {

            //DynamicLinkDomain = "https://quallogi.page.link",

            DomainUriPrefix = "quallogi.page.link",

            AnalyticsInfo = new AnalyticsInfo(),

            IosInfo = new IosInfo(),

            Link = "https://github.com/distriqt/ANE-Firebase/wiki/DynamicLinks---Create-Dynamic-Links",



        },



        Suffix = new Suffix { Option = "SHORT" },

        Name = "shortlink",





    });

    var response = await request.ExecuteAsync();

    return response.PreviewLink;

}



public static FirebaseDynamicLinksService AuthenticateServiceAccount(string serviceAccountEmail, string serviceAccountCredentialFilePath, string scopes)

{

    try

    {

        if (string.IsNullOrEmpty(serviceAccountCredentialFilePath))

            throw new Exception("Path to the service account credentials file is required.");

        if (!File.Exists(serviceAccountCredentialFilePath))

            throw new Exception("The service account credentials file does not exist at: " + serviceAccountCredentialFilePath);

        if (string.IsNullOrEmpty(serviceAccountEmail))

            throw new Exception("ServiceAccountEmail is required.");



        if (Path.GetExtension(serviceAccountCredentialFilePath).ToLower() == ".json")

        {

            GoogleCredential credential;

            using (var stream = new FileStream(serviceAccountCredentialFilePath, FileMode.Open, FileAccess.Read))

            {

                credential = GoogleCredential.FromStream(stream)

                     .CreateScoped(scopes);

            }



            return new FirebaseDynamicLinksService(new BaseClientService.Initializer()

            {

                HttpClientInitializer = credential,

                ApplicationName = "Firebasedynamiclinks Service account Authentication Sample",

            });

        }

        else if (Path.GetExtension(serviceAccountCredentialFilePath).ToLower() == ".p12")

        {



            var certificate = new X509Certificate2(serviceAccountCredentialFilePath, "notasecret", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable);

            var credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer(serviceAccountEmail)

            {

                Scopes = scopes

            }.FromCertificate(certificate));



            return new FirebaseDynamicLinksService(new BaseClientService.Initializer()

            {

                HttpClientInitializer = credential,

                ApplicationName = "Firebasedynamiclinks Authentication Sample",

            });

        }

        else

        {

            throw new Exception("Unsupported Service accounts credentials.");

        }



    }

    catch (Exception ex)

    {

        throw new Exception("CreateServiceAccountFirebasedynamiclinksFailed", ex);
