I want to integrate PlantUML diagrams into a Jekyll blog. I followed the "Integrate with Jekyll" link on https://plantuml.com/running. I installed the gem and updated my Jekyll's _config.yml file as suggested. But this led to the below runtime error. I posted a question about it on the plugin's github page https://github.com/yegor256/jekyll-plantuml/issues/20 but I did not have any hints so far.
Has anyone managed to successfully do this with a recent version of ruby/jekyll? Any hints on what I should try to fix these problems and get it running?
I'm a noob in ruby/jekyll, so I'm not sure what relevant information I should share here, but these are the version infos.
