how to add favicon with symfony 6 - symfony

Question

Good morning to you all,
I'd like to ask you for help because I don't understand where my problem with adding a favicon with Symfony 6 comes from.
I have two codes in mind, this one
<link rel="icon"
href="{{ '/images/' ~ 'favicon.jpg' }}"
type="image/x-icon"
src="" />
as well as this one
<link rel="icon"
href="{{ asset('/images/' ~ 'favicon.jpg') }}"
type="image/x-icon"
src="" />
None of the codes work.
I even get this error in Symfony when I put assets in my code, and I use yarn.
An exception has been thrown during the rendering of a template ("Asset manifest file "C:\wamp64\www\projet-conrad-angela/public/build/manifest.json" does not exist. Did you forget to build the assets with npm or yarn?").
<link rel="icon"
href="{{ asset('/images/' ~ 'favicon.jpg') }}"
type="image/x-icon"
src="" />

{# Run `composer require symfony/webpack-encore-bundle` to start using Symfony UX #}
If you have a solution, I would be delighted to help. Thank you.

You can do this:
<link rel="icon" type="image/jpg" href="{{ asset('favicon.jpg') }}" />
https://symfony.com/doc/current/reference/twig_reference.html#absolute-url
or
<link rel="icon" type="image/jpg" href="{{ absolute_url('favicon.jpg') }}" />
https://symfony.com/doc/current/reference/twig_reference.html#reference-twig-function-asset
and you can combine both:
<link rel="icon" type="image/jpg" href="{{ absolute_url(asset('favicon.jpg')) }}" />
