The error seems to be this. Does this file or folder exist in your repo?

Yes, this exists

assets/jupyter/blog.ipynb

Looks like this error: Jupyter notebook dark mode doesn’t work on first load · Issue #1545 · alshedivat/al-folio (github.com)

Ok good find, whats the best way to proceed? Simple as adding jupyter to gemfile?

I’m not an expert on that, but based on the thread, that should be it.

Seems like jupyter needs be installed in the python environment … is there a way to do this?

Simply listing that as a dependency should work: Manage build dependencies | Netlify Docs
