simple-ouath2获取令牌[object Object]时出错

Question

我尝试使用Outlook的API，并且我使用simple-oauth2来授权权限。我从微软文档中获取了片段，但是我收到了以下错误：

Error getting token [object Object]

...

TypeError: Cannot read property 'send' of null at tokenReceieved

我有一个函数可以将我引导到Azure的登录页面：

app.get('/authorize', (req, res) => {
  console.log("Request handler 'authorize' was called.");

  const { code } = req.query;
  // The authorization code is passed as a query parameter

  console.log(`Code: ${code}`);
  authHelper.getTokenFromCode(code, tokenReceived, res);
});

从单独的文件调用getTokenFromCode：

function getTokenFromCode(auth_code, callback, response) {
  var token;
  oauth2.authorizationCode.getToken(
    {
      code: auth_code,
      redirect_uri: redirectUri,
      scope: scopes.join(' ')
    },
    function(error, result) {
      if (error) {
        console.log('Access token error: ', error.message);
        callback(response, error, null);
      } else {
        token = oauth2.accessToken.create(result);
        console.log('Token created: ', token.token);
        callback(response, null, token);
      }
    }
  );
}

但问题出在tokenRecieved：

const tokenReceived = (req, res, error, token) => {
  if (error) {
    console.log(`Error getting token ${error}`);
    res.send(`Error getting token: ${error}`);
  } else {
    req.session.access_token = token.token.access_token;
    req.session.refresh_token = token.token.refresh_token;
    res.redirect('/logincomplete');
  }
};
