symfony turbo-stream doesn't load in turbo-frame - symfony

Question

I set up a project for test purpose, it works. But in another project, the above code doesn't work. The content of the turbo-stream appears in raw html and replaces the whole site.
//_parts/_dashboard_user_ranking.stream.html.twig
<turbo-stream action="update" target="the_frame_id" >
<template>
{{ include ("_parts/_dashboard_user_ranking.html.twig") }}
</template>
</turbo-stream>
//index.html.twig
{% block body %}
{{ parent()}}
<main class="container row overflow-auto">
<div class="col-md-10 mx-auto">
<ul class="nav nav-tabs">
<li class="nav-item">
<a class="nav-link" aria-current="page" href="{{ path('app_dashboard_rankings',{period:'5jours'}) }}">5 jours</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ path('app_dashboard_rankings',{period:'3mois'}) }}">3 mois</a>
</li>
<li class="nav-item">
<a class="nav-link" href="{{ path('app_dashboard_rankings',{period:'1an'}) }}">1 an</a>
</li>
{% for group in groups %}
<li class="nav-item">
<a class="nav-link" href="{{ path('app_dashboard_rankings',{period:'1an', groupID:group.id}) }}">{{ group.groupName }}</a>
</li>
{% endfor %}
</ul>
<turbo-frame id="the_frame_id"></turbo-frame>
</div>
</main>
{{ include ("footer.html.twig") }}
{% endblock %}
And finally the controller :
// classements seuls
#[Route('/classements-{period}-{groupID}', name: 'app_dashboard_rankings')]
public function classements(
Request $request,
FollowPointsRepository $followPointsRepository,
string $period = '5jours',
int $groupID = 0
): Response
{
// ...
// ...
$request->setRequestFormat(TurboBundle::STREAM_FORMAT);
return $this->render('_parts/_dashboard_user_ranking.stream.html.twig',[
'isUserInTop'=>$isUserInTop,
'classement'=>$classement
]);
}
As for the config, it is the same as in the test purpose project.
