Just saw your post, I actually fought with the same issue yesterday and wrote another workaround here: [fastpages] Plotly plot doesn't load, JS error in browser .
I didn’t know it was related to jemoji though, so it’s nice that you figured that out since that might be an easier fix for some users. So it seems that we now have two workarounds:
- Disable jemoji in the config.yml / Gemfile
or 2) Add a special cell at the top of the notebook to disable the plotly_mimetype renderer and add the missing require.js
