@nelsonic I just started redis-server, then ran npm start and didn't get any of the errors you have gotten, now that you've upgraded redis are you getting them? I have more or less no experience with redis so if this needs more in depth work to fix then could we pair or something?

What I did next:

rm -rf node_modules
npm install
npm run start-elm

Appears to work ...

hapi-error@1.8.0 fixes this issue. https://github.com/dwyl/hapi-error/releases/tag/v1.8.0 trying it now on localhost.

No more errors on server. ✅ 😥
