Hi All,
Looking for a bit of help with an error I'm getting while trying to follow ConsoleExample.cs located here <https://github.com/googleads/googleads-dotnet-lib/blob/master/examples/AdWords/CSharp/OAuth/ConsoleExample.cs>. The error occurs in DoAuth2Authorization at the GetAuthorization line and I’m not sure of the cause. *Line that errors:* string authorizationUrl = oAuth2Provider.GetAuthorizationUrl(); *The error I’m getting is:* System.NullReferenceException: Object reference not set to an instance of an object. at Google.Apis.Requests.Parameters.ParameterUtils.<>c__DisplayClass3_0.<InitParameters>b__0(RequestParameterType type, String name, Object value) in C:\Apiary\2018-05-10.07-58-36\Src\Support\Google.Apis.Core\Requests\Parameters\ParameterUtils.cs:line 92 at Google.Apis.Requests.Parameters.ParameterUtils.IterateParameters(Object request, Action`3 action) in C:\Apiary\2018-05-10.07-58-36\Src\Support\Google.Apis.Core\Requests\Parameters\ParameterUtils.cs:line 131 at Google.Apis.Auth.OAuth2.Requests.AuthorizationCodeRequestUrl.Build() in C:\Apiary\2018-05-10.07-58-36\Src\Support\Google.Apis.Auth\OAuth2\Requests\AuthorizationCodeRequestUrl.cs:line 50 at Google.Api.Ads.Common.OAuth.AdsOAuthProviderImpl.CreateAuthorizationUrl(String redirectUri) at GoogleAdwords_v2.Program.DoAuth2Authorization(AdWordsUser user) in C:\Users\mschwartz\source\repos\GoogleAdwords_v2\GoogleAdwords_v2\Program.cs:line 155 *Code:* using Google.Api.Ads.AdWords.Lib; using Google.Api.Ads.AdWords.v201806; using Google.Api.Ads.Common.Lib; using System; using System.Configuration; using System.IO; namespace GoogleAdwords_v2 { class Program { static void Main(string[] args) { AdWordsUser user = new AdWordsUser(); AdWordsAppConfig config = user.Config as AdWordsAppConfig; config.OAuth2RedirectUri = "http://localhost";; config.OAuth2Scope = "https://www.googleapis.com/auth/adwords";; config.DeveloperToken = "hidden"; config.OAuth2ClientId = "hidden"; config.OAuth2ClientSecret = "hidden"; config.OAuth2Mode = OAuth2Flow.APPLICATION; config.ClientCustomerId = "hidden"; //used to get the initial refresh token if (user.Config.OAuth2Mode == OAuth2Flow.APPLICATION && string.
