Unable to preload links: feature not supported

[BigBenJr]

Hi. I activated in config/packages/webpack_encore.yaml the preload of script & link tags via HTTP/2 Link header
preload: true

But I see this log error at each new request
unable to preload links: feature not supported

My base.html.twig used simple Encore entry tags

        {% block stylesheets %}
            {{ encore_entry_link_tags('app') }}
        {% endblock %}
        {% block javascripts %}
            {{ encore_entry_script_tags('app') }}
        {% endblock %}

Any idea on what should I do to activate this feature ?
Thanks !
