'Log in to a GMail account using OAuth 2.0 error

I use this code to login to gmail using oauth 2.o:

var clientSecrets = new ClientSecrets
                    {
                        ClientId = "xxx-xxxlpoimr2lrvo2.apps.googleusercontent.com"
                        //                      ClientSecret = "XXX"
                    };

                    var codeFlow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
                    {
                        // Cache tokens in ~/.local/share/google-filedatastore/CredentialCacheFolder on Linux/Mac
                        DataStore = new FileDataStore("CredentialCacheFolder", false),
                        Scopes = new[] { "https://mail.google.com/" },
                        ClientSecrets = clientSecrets
                    });

                    var codeReceiver = new LocalServerCodeReceiver();
                    var authCode = new AuthorizationCodeInstalledApp(codeFlow, codeReceiver);
                    var credential = await authCode.AuthorizeAsync(Chatting.Setings.CSetings.email, CancellationToken.None);

                    if (authCode.ShouldRequestAuthorizationCode(credential.Token))
                        await credential.RefreshTokenAsync(CancellationToken.None);

                    var oauth2 = new SaslMechanismOAuth2(credential.UserId, credential.Token.AccessToken);

I get error:
