How to resolve `Error: unable to verify the first certificate` while scrapping web page using cheerio?

Question

I am trying to learn web scrapping using cheerio. But when I am trying to scrap the content. In one of the site i am getting the following error:

Error: unable to verify the first certificate
    at TLSSocket.onConnectSecure (_tls_wrap.js:1515:34)
    at TLSSocket.emit (events.js:400:28)
    at TLSSocket._finishInit (_tls_wrap.js:937:8)
    at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:709:12) {
  code: 'UNABLE_TO_VERIFY_LEAF_SIGNATURE',

I am unable to understand as for other sites which i tried to scrap i did not got the error.

Here is my code:

const express = require('express');
const axios = require('axios');
const cheerio = require('cheerio');

const app = express();
const url = "--------------Link Of the site--------------";


axios.get(url)
    .then(response => {
        const html = response.data;
        const $ = cheerio.load(html);
        const articles = [];
        
        $('.text-left a',html).each(function(){
            const title= $(this).text();
            const url= $(this).attr('href');

            articles.push({
                title,
                url    
            })
        })        

        console.log(articles);

    })
    .catch(err => {
        console.log(err);
    })



app.listen(8080, () => console.log('Server running'));

Please guide me on how to resolve this error.
