C'est le dernier élément de la chaîne, donc pas d'url

le code complet :

<nav id="breadcrumb" class="cenote-breadcrumb cenote-breadcrumb--light">
<div role="navigation" aria-label="Fils d&#039;Ariane" class="breadcrumb-trail breadcrumbs" itemprop="breadcrumb"><div class="tg-container"><ul class="trail-items" itemscope itemtype="http://schema.org/BreadcrumbList"><meta name="numberOfItems" content="2" /><meta name="itemListOrder" content="Ascending" /><li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem" class="trail-item trail-begin"><a href="https://www.lesbougiesdechinouk.net/" rel="home" itemprop="item"><span itemprop="name">Accueil</span></a><meta itemprop="position" content="1" /></li><li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem" class="trail-item trail-end"><span itemprop="item"><span itemprop="name">Durance</span></span><meta itemprop="position" content="2" /></li></ul></div></div></nav>

C'est à cause du itemprop="item" sur le span avant Durance.

Comme ceci c'est mieux :
<nav id="breadcrumb" class="cenote-breadcrumb cenote-breadcrumb--light">
<div role="navigation" aria-label="Fils d&#039;Ariane" class="breadcrumb-trail breadcrumbs" itemprop="breadcrumb">
<div class="tg-container">
<ul class="trail-items" itemscope itemtype="http://schema.org/BreadcrumbList">
<meta name="numberOfItems" content="2" />
<meta name="itemListOrder" content="Ascending" />
<li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem" class="trail-item trail-begin">
<a href="https://www.lesbougiesdechinouk.net/" rel="home" itemprop="item">
<span itemprop="name">Accueil</span></a>
<meta itemprop="position" content="1" /></li>
<li itemprop="itemListElement" itemscope itemtype="http://schema.org/ListItem" class="trail-item trail-end">
<span itemprop="name">Durance</span>
<meta itemprop="position" content="2" /></li>
</ul></div></div></nav>

Le mieux est d'utiliser l'outil de test ici : https://search.google.com/structured-data/testing-tool?hl=fr
