I am new to javascript and nodejs
I am trying to generate a PDF table using node.js using google puppeteer.
I followed a youtube tutorial and the code below is the same as used in the tutorial. Note: I dont take credit for the below code.
I used a sample HTML template which I populate data from a json file.
const puppeteer = require('puppeteer');
const fs = require('fs-extra');
const hbs = require('handlebars');
const path = require('path');
const data = require('./stressData2.json');
const compile = async function(templateName, data){
const filePath = await path.join(process.cwd(), 'templates', `${templateName}.hbs`);
const html = await fs.readFile(filePath, 'utf-8');
return await hbs.compile(html)(data);
};
(async function(){
try{
const browser = await puppeteer.launch();
const page = await browser.newPage();
const content = await compile('stressTemplate', data);
await page.setContent(content);
await page.pdf({
path: 'pdfs/mypdf.pdf',
format: 'A4',
printBackground: true
});
console.log('done');
await browser.close();
await process.exit();
} catch(e){
console.log('Error', e);
}
})();
I am able to stress test till 100000 results, but when I push to 200000 I get the below error
{ Error: Protocol error (Runtime.callFunctionOn): Target closed.

I searched online and I am not able to fix this, has anyone faced this issue before I seen this post as well UnhandledPromiseRejectionWarning: Error: Protocol error (Runtime.callFunctionOn): Target closed. (Puppeteer) but not able to resolve it
