[solved] function get_url seems not to work

In my config.toml

[extra]
[[extra.nav]]
name = "Home"
url = "@/_index.md"
[[extra.nav]]
name = "Page"
url = "@/page.md"

In my index.html

{% include "nav.html" %}

In my nav.html

<nav>
  {% for i in config.extra.nav %}
    <a href="{{ get_url(path=i.url) }}">{{i.name}}</a>
  {% endfor %}
</nav>

Resulting html

<nav>
<a href="http://127.0.0.1:1111/_index.md">Home</a>
<a href="http://127.0.0.1:1111/page.md">Page</a>
</nav>

Not exactly what was expected from get_url function…

Edit : for some reason I had to reload Zola. (letting it here in case it helps someone)
