how to stop twitter login from displaying Undefined index: oauth_token and Undefined index: oauth_token_secret

Question

This is the function on twitteroauth.php file

I tried various examples for login in with twitter from my site, but I always get the same error

Undefined index: oauth_token in D:\wamp\www\login-with-twitter\oauth\twitteroauth.php on line 73

don't know what to do

 function getRequestToken($oauth_callback) {
    $parameters = array();
    $parameters['oauth_callback'] = $oauth_callback; 
    $request = $this->oAuthRequest($this->requestTokenURL(), 'GET', $parameters);
    $token = OAuthUtil::parse_parameters($request);
    $this->token = new OAuthConsumer($token['oauth_token'], $token['oauth_token_secret']);// line 73
    return $token;
  }

And also

Notice: Undefined index: oauth_token in D:\wamp\www\login-with-twitter\index.php on line 34 Notice: Undefined index: oauth_token_secret in D:\wamp\www\login-with-twitter\index.php on line 35

  if(isset($_GET['connect']) && $_GET['connect']=='twitter'){

            $connection = new TwitterOAuth($this->consumer_key, $this->consumer_secret);// Key and Sec
            $request_token = $connection->getRequestToken($this->oauth_callback);// Retrieve Temporary credentials. 

            $_SESSION['oauth_token'] = $token = $request_token['oauth_token']; //line 34
            $_SESSION['oauth_token_secret'] = $request_token['oauth_token_secret']; //line 35


            switch ($connection->http_code) {
              case 200:    $url = $connection->getAuthorizeURL($token); // Redirect to authorize page.
                header('Location: ' . $url); 
                break;
              default:
                echo 'Could not connect to Twitter. Refresh the page or try again later.';
    }
        }
