Firebase Functions times out when using puppeteer’s browser.newPage()

I have seen others having relatively minor performance problems with puppeteer running on Firebase Functions. In my case, Firebase times out before I can do anything with puppeteer, even with the memory and timeoutSeconds cranked all the way up.

Code:

import * as functions from "firebase-functions";
import puppeteer from "puppeteer";

const runScreenshot = async () => {
  console.log("Launching puppeteer...");
  console.time("launch");
  const browser = await puppeteer.launch();
  console.timeEnd("launch");

  console.log("Awaiting browser.newPage()...");
  console.time("newPage");
  const page = await browser.newPage();
  console.timeEnd("newPage");

  console.log("Setting viewport...");
  console.time("setViewport");
  page.setViewport({ width: 2000, height: 4000, deviceScaleFactor: 4 });
  console.timeEnd("setViewport");

  console.log("Goto page...");
  console.time("goto");
  await page.goto(
    "https://public.tableau.com/views/NCDHHS_COVID-19_Dashboard_Summary/NCDHHS_DASHBOARD_SUMMARY"
  );
  console.timeEnd("goto");

  console.log("Waiting for selector...");
  console.time("selector");
  await page.waitForSelector("#tab-dashboard-region");
  console.timeEnd("selector");

  // Wait for the spinner to go away
  await new Promise((r) => setTimeout(r, 100));

  console.time("href");
  const href = await page.$("#tab-dashboard-region");
  console.timeEnd("href");

  console.time("screenshot");
  href && (await href.screenshot({ path: "tmp/test.png" }));
  console.timeEnd("screenshot");

  return browser.close();
};

export const screenshot = functions
  .runWith({ memory: "2GB", timeoutSeconds: 540 })
  .pubsub.schedule("44 21 * * *")
  .timeZone("America/New_York")
  .onRun(() => {
    return runScreenshot();
  });

Here’s the resulting Firebase Functions log. It takes a few seconds to run puppeteer.launch(), and then browser.newPage() won’t finish at all in the 8 minutes it has before the timeout.

Answer

I fixed this by adding {args: [ '--no-sandbox', '--disable-setuid-sandbox']} to puppeteer.launch, as recommended here: https://github.com/puppeteer/puppeteer/issues/6568
