Error when creating new Nativescript and Angular shared project

I think nativescript/schematics is no longer supported in nativescript 8. I tried this 2 months ago, and wasn't successful in using nativescript/schematics with {N}8. Their recommendation as appears here is to use other solutions such as Nrwl Nx DevTools code-sharing platform, that is used for code-sharing in monorepos. Their two recommendations are using it with @nativescript/nx or with @nstudio/xplat).

Here are 2 more links from my previous research, by Nathan Walker (one of the creators of nativescript) explaining how to use code sharing with xplat: xplat multi-platform tools for Nx workspaces with Nathan Walker

And a newer one for sharing code with NativeScript and Capacitor (the Ionic wrapper).
