Error: the client closed the connection before the chart was done processing

"The client closed the connection before the chart was done processing"

It is a known issue for node > 16. I am on node 18 and having this issue.
I can confirm that the fix #337 works for node 18.

Are there any plans to implement this fix in the coming updates?

@fundamental-ricardo thanks for reporting!

I regret to inform you that we do not plan to update the Export Server version based on PhantomJS as it has been deprecated for a few years now (and a long list of problems arised on the way).

The good news is that we've recently released a beta version which uses Puppeteer as its headless browser library.

I encourage you to try this out, here's a short setup guide: https://github.com/highcharts/node-export-server#puppeteer-version-information

Please feel free to report any problems you encounter with the newest version and we will investigate it.
