Hey. I'm trying to use oauth authentication on an external website using NodeJS with passport-oauth2. When passport-oauth2 requests an access token, the forum returns Code: { statusCode: 400, data: '{"error":"invalid_scope"}' } Here are the details of the request : URL: Code: http://[forum address]/api/oauth/token Headers: Code: { 'Content-Type': 'application/x-www-form-urlencoded' } POST params: Code: grant_type=authorization_code&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Fxenforo%2Fcallback&client_id=[consumer key]&client_secret=[consumer secret]&code=490c237772e559cfe311771b2c3dc03b
