How to repeat:

git clone https://github.com/metanorma/mn-samples-un
cd mn-samples-un
bundle update
cd sources
bundle exec metanorma -t un -x presentation ECE_TRADE_C_CEFACT_2018_1E.adoc 

I've tried to update Gemfile:

source "https://rubygems.org"

gem "metanorma-cli"
gem "metanorma-un", git: "https://github.com/metanorma/metanorma-un", branch: "main"
gem "isodoc", git: "https://github.com/metanorma/isodoc", branch: "main"
gem "sassc"

but no success.
