Gateway timeout status while extending admin twig template

[adviva]

Prerequisites

• I understand and accept the project's code of conduct
• I have already searched in existing issues and found no previous report of this bug.

Describe the bug and add screenshots

The problem is about the extends of admin template twig from a module in ps 8.0, i think any root template.

When a module extends an admin template twig, this page get infinite loading or a gateway timeout status.

The extend works in previous ps 1.7.8 like this:
{% extends 'PrestaShopBundle:Admin/Product/ProductPage:product.html.twig' %}

Now i have changed the above using bundle name syntax, as described in the notable-changes of the doc:
{% extends '@PrestaShop/Admin/Product/ProductPage/product.html.twig' %}

This single line breaks the page loading.

Expected behavior

Template twig override from a module works and admin page is loaded

Steps to reproduce

1. Extends an admin template Twig from a module
   for example:

• @PrestaShop/Admin/Product/CatalogPage/catalog.html.twig
• @PrestaShop/Admin/Product/ProductPage/product.html.twig

2. Open the relative admin page

PrestaShop version(s) where the bug happened

8.0

PHP version(s) where the bug happened

7.4

If your bug is related to a module, specify its name and its version

@PrestaShop/prestashop-maintainers, can you check it if it's not due to the module ?

waiting for your feedback

Hello @adviva in the documentation https://devdocs.prestashop-project.org/8/modules/concepts/templating/admin-views/

the extend should be:

{% extends '@!PrestaShop/Admin/Product/CatalogPage/catalog.html.twig' %}

please notice the ! can you try this?

Hi @matks
many thanks for your suggestion! It was a really small change to do in our code.

Both the solution with the new namespace @PrestaShopCore and with @!PrestaShop works fine for me
