Error Related to deviceScaleFactor
So Just Using This Code Works Fine: Const Browser = Await Puppeteer. Launch(); Const Page = Await Browser. newPage(); Await Page. Goto('); Await Page...
So just using
This code works fine:
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(');
await page.setViewport({width: 1280, height: 978, deviceScaleFactor: 1});
await page.screenshot({path: 'example2.jpg'});
await browser.close();
But if I change deviceScaleFactor to 2 (because I'm on a retina screen) I get this error: Error running your code. Error: Protocol error (Page.captureScreenshot): Target closed.
Any ideas why? Seems to work if I change the URL to example.com as well, but not if I try other websites.

This error no longer appears as of Puppeteer v1.5.0.
The website that you were trying to access had maximum-scale=1 in the source code:
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
Therefore, deviceScaleFactor: 2 appears to have been failing due to this fact.
