firebase - Can't initialize FirebaseAdmin because of 'Field not found: 'Initializer.DefaultHandleUnsuccessfulResponseFunc'' issue

Question

Could you please help me with the issue that I have. I'm using FirebaseAdmin .NET C# library to send notification to firebase server. When it's trying to initialize the FirebaseAdmin with command FirebaseApp.Create (see code below) i got an error:

System.MissingFieldException: Field not found: 'Initializer.DefaultHandleUnsuccessfulResponseFunc'. at FirebaseAdmin.Util.RetryOptions.get_Default() at FirebaseAdmin.Messaging.FirebaseMessagingClient.Create(FirebaseApp app) at FirebaseAdmin.Messaging.FirebaseMessaging..ctor(FirebaseApp app) at FirebaseAdmin.Messaging.FirebaseMessaging.<>c__DisplayClass5_0.b__0() at FirebaseAdmin.FirebaseApp.GetOrInit[T](String id, ServiceFactory`1 initializer) at EventNotifier.FirebaseNotifier.FirebaseMessageSender.d__4.MoveNext() in C:gitlab-runneruilds4bEsN_fPflEventNotifierEventNotifierFirebaseNotifierFirebaseMessageSender.cs:line 66

The code is working perfectly on other servers (Windows 10, Windows Server 2016). However, on current server (Windows Server 2016) I have this issue.

The code is below:

public class FirebaseAppClient { private static readonly object _syncRoot = new object(); private static FirebaseAppClient _instance;

private FirebaseAppClient()
{
    if (FirebaseApp.DefaultInstance == null)
    {
        FirebaseApp = FirebaseApp.Create(new AppOptions()
        {
            Credential =
                GoogleCredential.FromJson(
                    JsonConvert.SerializeObject(new FirebaseConfigProvider().GetConfiguration())),
        });
    }
    else
    {
        FirebaseApp = FirebaseApp.DefaultInstance;
    }
}

public static FirebaseAppClient GetInstance()
{
    if (_instance == null)
    {
        lock (_syncRoot)
        {
            _instance = new FirebaseAppClient();
        }
    }

    return _instance;
}

public FirebaseApp FirebaseApp { get; private set; }

}

Please help!
