laravel mix. Incorrect route (404)

[jjmontalban]

Hi

When I compile with npm run watch and load app in Js console appear this error:

I can solve changing:

<script src="{{ mix('js/app.js') }}"></script>

for

<script type="text/javascript" src="{{ asset('public/js/app.js') }}"></script>

in resource/view/app.blade.php

But I want to use Laravel Mix sessions

How Can I solve it?

best regards
