Puppeteer failed to launch browser process

I am trying to use puppeteer in cron service, but I keep getting this error:

Jul 24 06:47:37 PM Error: Failed to launch the browser process! spawn /usr/bin/chromium-browser ENOENT

Below are the 3 things I’ve tried.

1. Error could not found chromium - #8 by jeremy-render. so I have cron-build.sh that contains:

#!/usr/bin/env bash
# exit on errorset -o errexit
# source: https://community.render.com/t/error-could-not-found-chromium/9848/2
npm install
# npm run build # uncomment if required

# Store/pull Puppeteer cache with build cache
if [ ! -d $PUPPETEER_CACHE_DIR ] ; then 
  echo "...Copying Puppeteer Cache from Build Cache" 
  cp -R $XDG_CACHE_HOME/puppeteer/ $PUPPETEER_CACHE_DIR
else 
  echo "...Storing Puppeteer Cache in Build Cache" 
  cp -R $PUPPETEER_CACHE_DIR $XDG_CACHE_HOME
fi

Note, I use [ instead of [[ because [[ is compile error when I deployed, I am not familiar with bash so I hope this is correct.

2. I also followed this post: Docker: puppeteer not working on a Express (NestJS) app - #4 by Jade_Paoletta so I have the following config passed to puppeteer:

{
  executablePath: '/usr/bin/chromium-browser',
  headless: 'new',
  slowMo: undefined
}

3. I also created . puppeteerrc.cjs as suggested here Error could not found chromium - #9 by tomstove

NOTE:
When I ssh’ed into the service, I checked the suggested path /opt/render/project/puppeteer and when I listed the content, I did not see puppeteer, as show below.

Please advise on how to run puppeteer.

Hi there,

I think the issue here is that it was never cached because you added the build script to restore/copy Chrome to/from the cache after the first time the puppeteer module was installed.

Can you try building again with a clear cache? Unfortunately for cron jobs, we don’t have an easy way to do this, you will need to use our API: https://api-docs.render.com/reference/create-deploy, with clearCache set to clear.

You should only need the build script, nothing else.

I’d be also interested to know why it failed when using [[, it should work.

Keith, it’s working now and to be honest since i tried so many things, I am not sure which one works for me. However, [[ still does not work, [ works however.
