Fyi;

I've also run the sample.tex shown in the attachment in

https://puszcza.gnu.org.ua/bugs/?371

Run it using lualatex only to start with. Not tex4ht.
But I get this error

This is LuaTeX, Version 1.0.4 (TeX Live 2017

May be I am doing something wrong. I do not know. It will
help to post the commands to use to run the sample.tex
also, just in case.

Thanks
