Wrong URL from plugin

[zagreusinoz]

Overview

I'm mounting plugins that I'm developing as the documentation says and in my plugin I'm trying to get the url of some scripts like this:
$path = dirname(plugin_dir_url( __FILE__ )) . '/scripts/js/script.js';

However this returns the URL:
http://localhost:8080/app/wp-content/plugins/customer-manager/scripts/js/script.js?ver=5.6.8

whereas the actual URL should be:
http://localhost:8080/wp-content/plugins/customer-manager/scripts/js/script.js?ver=5.6.8

without the app directory.

Any help would be much appreciated. Thanks!

@zagreusinoz I think the issue is with your function, not the docker setup.

You should be doing just plugin_dir_url(__FILE__) instead of wrapping that in a dirname() call.

[zagreusinoz]

All that dirname should be doing is to go up a level in the path though I thought. It shouldn't add anything additional to the path itself.

I just double checked it and that is indeed what it does. Even without dirname the extraneous /app/ is part of the path.
