Hi, we're using Puppeteer for launching the headless browser process on the server that will open the URL to the saved object in Kibana and take the screenshot.

If you've already checked the troubleshooting information on Reporting in the Elastic documentation and that didn't resolve it, also take a look at the troubleshooting information in the Puppeteer documentation: https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md

We're working on improving the startup and diagnostic capabilities for reporting. Please bear with us! Thanks

@tsullivan after installed dependencies listed in https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md, i can now generate pdf report, thank you very much.

Glad to hear you got it working!

I have a pull request open to improve the documentation for Getting Started and Troubleshooting with reporting: https://github.com/elastic/kibana/pull/31539/files

If you have a minute, I'd appreciate if you could take a look and see if these changes would have helped the issue for you.

Thanks!
