Hey all, when running the following command, I get an error with the mdb-pro toast service.  Any idea on how to resolve this? My end goal is to build an Angular PWA, and this command builds my app shell from the home route.

COMMAND
./node_modules/.bin/ngu-app-shell --module src/app/app.module.ts --out dist/index.html
