puppeteer margins:none equivalence of chrome print

Even when i set margins 0 all. I am keep getting default margins my @page{ margin: 0 !important; padding: 0 !important; } i was searching long time for this and did found nothing that would help.

^1.9.0 puppeteer ubuntu 18.04 10.15.1 node

this.browser = await puppeteer.launch({args: ['--no-sandbox', '--disable-setuid-sandbox']});
const page = await this.browser.newPage();
// @ts-ignore
await page._emulationManager._client.send('Emulation.setDefaultBackgroundColorOverride', {
  color: {
    r: 0,
    g: 0,
    b: 0,
    a: 0
  }
});

await page.goto(
  'https://google.com',
  {
    waitUntil: 'networkidle0'
  }
);
await page.pdf({
  path: '/home/pdf.pdf',
  printBackground: true,
  displayHeaderFooter: true,
  format: 'A4',
  preferCSSPageSize: true,
  headerTemplate: '<span></span>',
  footerTemplate: '<span></span>',
  margin: {
    left: '0',
    right: '0',
    top: '0',
    bottom: '0'
  };
});```

use

body {
    margin: 0;
}

For me, this css did the trick:

@page {
  size: A4 portrait;
  margin: 0;
}
