Pyppeteer Browser closed unexpectedly in heroku

Question

I recently deployed an app in heroku . It uses python pyppeteer package. I didnt had any issues while testing on repl.it. But unfortunately in heroku the browser keeps crashing.

I used requirement.txt for installing pyppeteer package. I also tried using apt heroku buildpack for installing the requirements needed for pupeteer to work as per here

My program :

async def mainer(link, path, is_image):
    browser = await launch(args=['--no-sandbox'])
    page = await browser.newPage()
    await page.goto(link)
    if is_image:
        await page.screenshot({'path': f'{path}', 'fullPage': True, 'type': 'png'})
    else:
        await page.pdf({'path': f'{path}'})
    await browser.close()

here is the full traceback error from heroku :

@David Hey thanks for the comment , but i already fixed it by using Chromedriver from Heroku buildpack in Executablepath instead of the one bundled with Pyppeteer :) — Alen Paul Varghese, Jul 24 '20 at 18:31

For Heroku Deployment I had this issue

pyppeteer.errors.BrowserError: Browser closed unexpectedly:

Following this, I just added '--no-sandbox' mode when launching Puppeteer and 'headless' set to True.

from pyppeteer import launch
    BROWSER = await launch({'headless': True, 'args': ['--no-sandbox']})

I added 2 buildpacks in my dyno settings:

This worked for me

If we care using the buildpack provided by Heroku, there will be an environmental variable called GOOGLE_CHROME_SHIM. We can use this variable as an argument to pyppeteer.launch() or webdriver.Chrome().

Have the same problem than you over heroku and pyppeteer! My code it's exactly as yours. I'm using the buildpack: https://github.com/jontewks/puppeteer-heroku-buildpack.git How did you solve it? Can you help me? I am a newbie in heroku – dina May 24 '21 at 17:18

Using Django, when i call requests_html HTMLSession at start of my application i needed to add puppeteer-heroku-buildpack , heroku-buildpack-google-chrome as first buildspacks and heroku/python as last. In code had to add something like this: session = HTMLSession(browser_args=["--no-sandbox"])
