Puppeteer unable to run on heroku

Question

I deployed an app on heroku, and i added the puppeteer Heroku buildpack.

After a succesful redeployment, i try to run it and it fails. Using heroku logs -t, i get this error message:

2018-09-07T13:16:10.870497+00:00 app[web.1]: Error: Failed to launch chrome!

Here is what worked for me. First, I clear all my buildpacks and then I added the puppeteer-heroku-buildpack and the heroku/nodejs one:

$ heroku buildpacks:clear
$ heroku buildpacks:add --index 1 https://github.com/jontewks/puppeteer-heroku-buildpack
$ heroku buildpacks:add --index 1 heroku/nodejs

Then, add the following args to the puppeteer launch function:

const browser = await puppeteer.launch({
  'args' : [
    '--no-sandbox',
    '--disable-setuid-sandbox'
  ]
});

Finally, deploy it back to Heroku:

$ git add .
$ git commit -m "Fixing deployment issue"
$ git push heroku master
