Ok, just figured out what’s wrong…
I based my solution in this topic - https://forum.quasar-framework.org/topic/2358/quasar-v16-build-n-e-is-not-a-function
There is something wrong with the default router definition within this version (0.16.4).
I followed the other not default way to import the pages on the documentation - https://quasar-framework.org/guide/app-adding-pages-and-layouts.html
And everything worked out fine.
