I can't find hints online. I am hoping someone can help me. That is the error message I get: ! Undefined control sequence. <argument> ... \hspace {\z@ }\ignorespaces \color {lightgray}\tiny {[1]}\end... l.72 \paragraphnumber{[1]} I had some error messages in the past, usually due to missing squared brackets which I resolved by using --trace to check where parsing was slowing down (that is where the brackets were missing), but this time --trace does not provide any hints. I can convert the document from .md to .pdf (without the filter); that is the command I use: $ pandoc file.md --pdf-engine=xelatex -o file.pdf ...but when I add count-para.lua filter: $ pandoc file.md --pdf-engine=xelatex --lua-filter=count-para.lua -o file.pdf I get the error message mentioned above. I also tried with another document. I get the same error message. I tried contacting the author of the filter, in vain. Do you have a hint about how I could troubleshoot or fix this issue? Does the filter need to be updated? $ pandoc -v pandoc 2.5 Compiled with pandoc-types 1.17.5.4, texmath 0.11.2.2, skylighting 0.7.7 I use Trisquel GNU/Linux 10.0.1.
