Good morning, as I upgraded my stack on heroku I’ve noticed a message telling me to use a newer chrome buildpack rather than the older buildpacks I’ve used. Logically I proceeded to install this buildpack per the instructions. selenium.webdriver works fine, but pyppeteer doesn’t work at all, this is the error I’ve encountered:

I’ve tried all solutions available on StackOverflow, like installing the puppeteer buildpack, that doesn’t work though, I’ve added the --disable-setuid-sandbox argument to pyppeteer, doesn’t work either.

MRE:

from pyppeteer import launch
import asyncio
import os

exec_path = os.environ.get("GOOGLE_CHROME_SHIM", None)


async def main():
    await launch({
        "headless": True,
        "args": {
            "--no-sandbox", "--disable-setuid-sandbox"
        },
        "executablePath": exec_path
    })


asyncio.run(main())
