The sectnumoffset extension works for me when outputting HTML, but gives me this error when outputting PDF:

I use docker-asciidoctor and am running asciidoctor-pdf with additional flags -r ./lib/sectnumoffset-treeprocessor.rb -a sectnums -a sectnumoffset=9 --trace.

If I remove those extra flags the PDF renders fine, so somehow this extension is interfering somehow, maybe some ordering issue?

This is due to a conflict between Asciidoctor core and an older version of Rouge when the include Asciidoctor statement is used (by the extension). You can fix it by upgrading Rouge to the latest version (see https://rubygems.org/gems/rouge). A corresponding fix in Asciidoctor will be in the 2.0.11 release. See asciidoctor/asciidoctor#3623

Thanks!

I'm also a bit out of date with the docker image:

REPOSITORY                       TAG                 IMAGE ID            CREATED             SIZE
asciidoctor/docker-asciidoctor   latest              0c383e26e3d9        7 months ago        428MB

so I'll see if updating that fixes it.
