Running bundle install does not change anything unfortunately.

I had similar problems. Have you installed ruby and jekyll @mathurinm ?
e.g., if you are on a mac, https://jekyllrb.com/docs/installation/macos/

This fixed the issue with bundle install for me. However, running the devcontainer or bundle exec jekyll serve --future locally still fails for me because an figure.html file is not found:

Liquid Exception: Could not locate the included file 'figure.html' in any of ["/path/to/repo/2026/_includes"]. Ensure it exists in one of those directories and, if it is a symlink, does not point outside your site source.

this seems unrelated to my local changes. any ideas @n-gao ? 🙏

[n-gao]

Do you have exact instructions (from checking out the git to getting to the error) to reproduce the error?

[janfb]

The figure.html error was resolved, it was on my side. In the end, I wasn't able to launch the devcontainer in vscode, but building locally worked for me. Thanks for checking 🙏
