Catch errors properly in Node.js script for Puppeteer

Hi, I'm using Puppeteer to generate PDF documents (see [login to view URL]). This works well when there are no errors, but when there's a page error or when the URL is wrong (for example), then the script just hangs. From what I understand this is because the promises after the promises that "crashes" are still trying to resolve, but I'm not a Node.js expert so I'm not sure. I'm calling the node.js script form PHP, but the same thing happens when I call in the command line. The script is similar (but more elaborate) to the default script that's on the Puppeteer website: const puppeteer = require('puppeteer'); (async () => { const browser = await [login to view URL](); const page = await [login to view URL](); await [login to view URL]('[login to view URL]', {waitUntil: 'networkidle2'}); await [login to view URL]({path: '[login to view URL]', format: 'A4'}); await [login to view URL](); })(); If the goto event fails for example then the script doesn't terminate. What I need is someone to: 1) rewrite the script so it catches errors properly in a way that I can use them OUTSIDE the script as well (so when the PHP call is finished); I can read the output that the script generates so I'm guessing a combination of [login to view URL] and exit codes would work. You need to catch errors with the [login to view URL], but also [login to view URL] (error). More info on how other people seem to do this is on [login to view URL] and [login to view URL] and various other places on the web. 2) supply a way to call multiple instances of Puppeteer in a pool or other way so that I can just start a new page instead of a new browser every time I need a conversion. These instances don't need to live long, but I need to have at least one open all the time so the conversion can happen quickly. This is needed because I do many thousands of conversions a day and the time to wait for the browser to open is too long. I need this done quickly so only reply if you're available to do this quickly and have the right experience with node.js Thanks!
