This is definitely a bug. You are hitting a branch in a conditional that bumps into a typo.

The reason you are hitting that branch is become the section is missing an ID. You can workaround this temporarily by enabling section IDs when invoking Asciidoctor PDF.

asciidoctor-pdf -a sectids -a pdf-page-size=A4 production/training-neo4j-in-production.adoc

Fixed!

This fix will be available in the next release.
