jekyll does not copy files from assets

[mathurinm]

In last year's track, it was possible to not use docker, and simply run :
bundle exec jekyll serve

This year, doing so results in :

[2025-11-06 10:59:29] ERROR '/2026/assets/js/progress-bar.js' not found.
[2025-11-06 10:59:29] ERROR '/2026/assets/js/search-setup.js' not found.

Changing baseurl to "" in _config.yml does not fix the issue: the contents of assets/ are not copied into _site/assets by jekyll. How to fix this?

The issue was solved by ionstalling nodejs: sudo apt-get install nodejs, that Terser was missing in order to work properly. I was getting the following error in the logs:
Terser Exception: Could not find a JavaScript runtime. See https://github.com/rails/execjs for a list of available runtimes.

I encountered the same problem, also solved by adding following in devcontainer.json:

"postCreateCommand": "sudo apt-get update && sudo apt-get install -y nodejs",

node should be available within the devcontainer?
