"Some requested scopes were invalid. {invalid=[Calendar]}"

[JTeagle]

I'm trying to access Calendars v3 using the OAuth2 mechanism. The code
I'm using is basically what was in the sample:

NativeApplicationClient provider = new
NativeApplicationClient(GoogleAuthenticationServer.Description);
provider.ClientIdentifier = "as given by API Console for
installed application";
provider.ClientSecret = "as given by API Console for
installed application";
OAuth2Authenticator<NativeApplicationClient> auth = new
OAuth2Authenticator<NativeApplicationClient>(provider,
GetAuthorization);

CalendarService service = new CalendarService(auth);
CalendarList calendarList =
service.CalendarList.List().Fetch();

and:

private static IAuthorizationState
GetAuthorization(NativeApplicationClient arg)
{
// Get the auth URL:
IAuthorizationState state = new AuthorizationState(new[]
{ CalendarService.Scopes.Calendar.ToString() });
state.Callback = new
Uri(NativeApplicationClient.OutOfBandCallbackUrl);
Uri authUri =
arg.RequestUserAuthorization(state);

// Request authorization from the user (by opening a
browser window):
Process.Start(authUri.ToString());
Console.Write(" Authorization Code: ");
string authCode = Console.ReadLine();
Console.WriteLine();

// Retrieve the access token by using the authorization
code:
return arg.ProcessUserAuthorization(authCode, state);

}


When it comes to authorise the request, though, I get an 'invalid
scope' page. Any idea what I'm doing wrong?

Hello,

In the GetAuthorization function, you should use:

  CalendarService.Scopes.Calendar.GetStringValue()

To get a valid scope value:

Best,

Alain

Ugh, thanks - that fixed it. Silly mistake on my part!
