Argument 2 must be an instance of paginator in symfony - symfony

Question

I'm having an error using the paginator bundle inside a twig loop , I think missions is waiting for a sliddingpagination and not a persistentcollection , I think it's in the controller in the FindAllVisibleQuery, like waiting for an array but IDK..
This is the error I'm receiving:
Argument 2 passed to
Knp\Bundle\PaginatorBundle\Twig\Extension\PaginationExtension::render()
must be an instance of
Knp\Bundle\PaginatorBundle\Pagination\SlidingPaginationInterface,
array given, called in

Answer 1

you need to edit your repository class to return the QueryBuilder instead of the Query itself.
Your function must be something lke that:
public function findAllVisibleQuery(MissionSearch $search): Query
{
$query = $this->findVisibleQuery();
if ($search->getMaxGain()) {
$query = $query
->andWhere('p.price <= :maxgain')
->setParameter('maxgain', $search->getMaxGain());
}
if ($search->getDeltaVille()) {
$query = $query
->andWhere('m.ville = :deltaville')
->setParameter('deltaville', $search->getDeltaVille());
}
if ($search->getOptions()->count() > 0) {
$k = 0;
foreach($search->getOptions() as $option) {
$k++;
$query = $query
->andWhere(":option$k MEMBER OF m.options")
->setParameter("option$k", $option);
}
}
return $query;
}
