@jspenc72 I faced the same 'AssertionError [ERR_ASSERTION]: I .....' and it got resolved by upgrading 'gulp-eslint' to version '^5.0.0' in the 'package.json'. Additionally, i had to follow the instructions provided here to get the default app up and running via 'gulp serve' command

[Awk34]

Yes, please read the documentation, as gulp serve is no longer the recommended way of starting up the app.

@kkrb thanks for the response!
