scraper via puppeeter in node js - got some exectution issues

Question

this is my code:

const puppeteer = require('puppeteer');
const DOG_NAME = 'section.adopt.yd-amuta > div.container > div.row.yd-dog-count > div.col-xs-12 > div.adopt-head > div.row> div.col-sm-6.col-xs-12 > div.adopt-breadcrumb-title > h2 > span';

let names = [];

async function run() {
  let browser = await puppeteer.launch({
    headless: false,
  });

  let pages = await browser.pages();
  let num =1;
for(; num < 6329; num++){   
  await pages[0].goto('http://www.yad4.co.il/dogs#' + num);

  let dogCard = await pages[0].$$('.col-md-4.col-sm-4.col-xs-6');

  for (let i = 0; i < dogCard.length; i++) {
    await pages[0].waitForSelector('.col-md-4.col-sm-4.col-xs-6');
    dogCard[i].click();
  }
  console.log('Finished clicking.');

  let count = 0;

  while (count < dogCard.length) {
    pages = await browser.pages();
    count = pages.length;
  }

  for (let i = 1; i < dogCard.length; i++) {
    let name = await pages[i].evaluate((sel) => {
      return document.querySelector(sel).innerHTML;
    }, DOG_NAME);

    names.push(name);
    await pages[i].close();
  }

  for (let i = 0; i < names.length; i++) {
    console.log(`${i + 1}` + ':' + `${names[i]}`);
  }
if(num == 6329 ){
  browser.close();
}
}
}
run();

I get this error:
