Timeouts with 1.12.2 on cloud function #3944

  • Puppeteer version: 1.12.2
  • Platform / OS version: Firebase Cloud Function
  • Node.js version: 8

We are using Puppeteer on a Firebase Cloud Function to automatically render PDFs. I upgraded to Puppeteer 1.12.2 and the cloud function started to run into 60s timeouts as soon as there are multiple concurrent requests. Some additional logging shows that some invocations are even hanging at the very beginning of the function. With 1.11.0 everything is fine. I know that this is not much information for reproducing this issue, but I wanted to make you aware anyways. We're staying with the older version for now. Feel free to close.

@neelance thanks for letting us know. Any chance you can share more information? Which calls timeout for you? Do you use the bundled chromium instance or a custom one? If custom, than which version?

I'm using the bundled chromium with --no-sandbox. It does not seem to be a specific call. I put a log statement at the beginning of the function and sometimes the only logs I got were Function execution started and Function execution took 60002 ms, finished with status: 'timeout', which suggests that the function didn't even start to run. The function was triggered by a change to the Firebase Realtime Database. It's all quite strange and I don't really now how to narrow it down.

I am having issues with timeouts with Node 8 and 1.12.2 as well.
Sorry, I don't have more info. I haven't had time to debug it deeply.
I rolled back to 1.10.0, which does not seem to get stuck.

I'm also getting timeouts when upgrading from 1.11.0 to 1.12.2

Look like issue after bugfix: #609 - page.waitForSelector doesn't work on

After few loads of same page I got timeouts on page.waitForSelector. Also my puppeteer instance freezes on (but only after that few loads). Timeout exception stack trace:

TimeoutError: waiting for selector ".selector" failed: timeout 30000ms exceeded, TimeoutError: waiting for selector ".selector" failed: timeout 30000ms exceeded
    at new WaitTask (project_dir\node_modules\puppeteer\lib\DOMWorld.js:554:28)

Same code works perfectly fine on v1.11.0
