Hey! I had the same problem. I think it is some mistake
I have replaced "adapter": "@slicemachine/adapter-universal" with "adapter": "@slicemachine/adapter-nuxt", and seems like it works fine.
Slice Machine only supports Next.js and Nuxt at this time. We are currently exploring which frameworks we will support in the future (including the possibility for a “universal” adapter that supports any framework). Until then, Slice Machine will not work in a Remix application. It's possible to manually use the Next.js adapter (@slicemachine/adapter-next ), but it is not something we recommend or support.---
Slice machine works fine, albeit in a more limited way with remix and I'm OK with that.
The problem I wanted to highlight was that the latest config version references a package that doesn't exist on NPM. Not only that, the error doesn't suggest a way for the developer to fix it which wastes a lot of time hunting for fixes.
