Hey there @kris.bravo! I was revisiting this article and just noticed I missed your comment! Really sorry about that. Did you ever get this resolved? I’ve tried a couple ways to reproduce it and I think it could be how you’re importing it? Can you confirm that you have this line in main.js:
import { Auth0Plugin } from "./auth"
And double check that the @auth0/auth0-spa-js package exists in package.json. Let me know if that helps!
