Question

Bot works fine locally and even in the simlulated Heroku local heroku local web, but crashes after a minute or two when hosted on their servers online.
I have installed the buildpack for puppeteer:
https://github.com/jontewks/puppeteer-heroku-buildpack
I cleared my build cache:
https://help.heroku.com/18PI5RSY/how-do-i-clear-the-build-cache
I have tried to manually set my worker scaling to 1 heroku ps:scale web=1
This is my puppeteer browser launch arguments: {args: ["--no-sandbox", "--disable-setuid-sandbox"],}
List of my dependencies below:
discord.js
dotenv
node-fetch
puppeteer
fs
Logs are useless:

I had a similar problem and applied this:
(Copied from Puppeteer Troubleshooting site. And It worked!)
Running Puppeteer on Heroku
Running Puppeteer on Heroku requires some additional dependencies that aren't included on the Linux box that Heroku spins up for you. To add the dependencies on deploy, add the Puppeteer Heroku buildpack to the list of buildpacks for your app under Settings > Buildpacks.
The url for the buildpack is https://github.com/jontewks/puppeteer-heroku-buildpack
Ensure that you're using '--no-sandbox' mode when launching Puppeteer. This can be done by passing it as an argument to your .launch() call: puppeteer.launch({ args: ['--no-sandbox'] });.
When you click add buildpack, simply paste that url into the input, and click save. On the next deploy, your app will also install the dependencies that Puppeteer needs to run.
If you need to render Chinese, Japanese, or Korean characters you may need to use a buildpack with additional font files like https://github.com/CoffeeAndCode/puppeteer-heroku-buildpack
There's also another simple guide from #timleland that includes a sample project: https://timleland.com/headless-chrome-on-heroku/.
