plantuml diagrams in generated PDF

[isylhdin]

PlantUml diagrams are not displayed in the generated PDF (Images are displayed correctly) :

:imagesdir: images

plantuml::images/test.puml[format=png,alt="Test",align="center"]

I don't get any error during the PDF generation

Did you install and require asciidoctor-kroki (see: https://github.com/Mogztter/asciidoctor-web-pdf#asciidoctor-extensions)?
Could you share the command you are running?

Thank you for your answer.
Oops I forgot to install this extension.

Here is what I've tried :

npm i asciidoctor-kroki --save-dev
asciidoctor-pdf --require asciidoctor-kroki doc/index.adoc -o dist/test.pdf && del-cli doc/test.html

I am behind a proxy and got this error :

Failed to load resource: net::ERR_PROXY_CONNECTION_FAILED at https://kroki.io/plantuml/png/....

If you are behind a proxy, then you will need to run Kroki locally: https://github.com/mogztter/asciidoctor-kroki#using-your-own-kroki
