如何获取<a> tag in div through cheerio or nodejs

Question

How do I fetch specific <a> tags through cheerio and nodejs? In the following code I am trying to fetch #topstuff > div.card-section > div._hUb > a

, but when I am trying it's not returning anything.

var cheerio = require('cheerio');

var request = require('request');

var b;

request
({
    method: 'GET',
    url: 'https://images.google.com/searchbyimage?image_url=http://static2.jetpens.com/images/a/000/044/44756.jpg?s=8d7a25b1901bfcfddcd8a2210ad355d7'
}, function(err, response, body) {
    if (err) return console.error(err);
    $ = cheerio.load(body);
    $('div#topstuff').find('div.card-section > div._hUb > a').each(function (index, element, body) {
     var b = $(this).attr('href');
      console.log(b.text());

    }); 

});
