page.pdf error - 18 page PDF

Tell us about your environment:

• Puppeteer version: 1.4.0
• Platform / OS version: Ubuntu 16.04.4 LTS
• URLs (if applicable):

• http://snapper2.webcmstools.com/test
• http://snapper2.webcmstools.com/pdf?url=http://pms.dasaproperties.com
• http://snapper2.webcmstools.com/pdf?url=http://pms.dasaproperties.com/test-owner-statement.html
• http://snapper2.webcmstools.com/simple-pdf?url=http://pms.dasaproperties.com
• http://snapper2.webcmstools.com/simple-pdf?url=http://pms.dasaproperties.com/test-owner-statement.html

• Node.js version: v8.11.2

This works fine for smaller PDFs / pages, but fails, pretty consistently, for an 18-page PDF (statement report). It is relatively small considering the amount of pages (about 88KB). I was able to get it to work once, but have not been able to replicate this success.

What steps will reproduce the problem?

Various versions of the following

/test

          const browser = await puppeteer.launch()
          const page = await browser.newPage()

          await page.goto('http://pms.dasaproperties.com/test-owner-statement.html', { waitUntil: 'networkidle2' })
          const doc = await page.pdf({path: '/tmp/random-page.pdf', landscape: false, format: 'letter', printBackground: true})

          await browser.close()
          return h.file('/tmp/random-page.pdf').vary('x-magic');

-or-

          const browser = await puppeteer.launch()
          const page = await browser.newPage()

          await page.goto('http://pms.dasaproperties.com/test-owner-statement.html', { waitUntil: 'networkidle2' })
          const doc = await page.pdf({landscape: false, format: 'letter', printBackground: true})

          await browser.close()
          return h.response(doc).type('application/pdf')

What is the expected result?

A resulting PDF. Like the following using PhantomJS: http://snapper.webcmstools.com/pdf?url=http://pms.dasaproperties.com/test-owner-statement.html

What happens instead?

The following errors:

Closing this. We figured out what was causing the problem, and it had nothing to do with the fact that the PDF was 18 pages long. I will open a new issue if necessary. Thanks!

@mtwhelan do you have any more information? I’m experiencing the same issue.
