Popper not found when using vuejs in Laravel

Question

In one of my projects Laravel (5.8) I am using Vuejs, basically only created some components, I did not make any changes in the default configuration of Vue.

But I’m getting the bug:

Failed to load resource: the server responded with a status of 404 (Not Found) for Popper.js.map

I don’t understand since the Bootstrap.js file on Youtube has the snippet:

try {
    window.Popper = require('popper.js').default;
    window.$ = window.jQuery = require('jquery');

    require('bootstrap');
} catch (e) {}
