Can not use custom search repository

[ghost]

I am trying to use a custom repository as described here: https://github.com/FriendsOfSymfony/FOSElasticaBundle/blob/7f3d131a8cf58cf83f40d85bcd49c03bb0e7caea/doc/cookbook/custom-repositories.md

Here is my code

# config/packages/fos_elastica.yaml

fos_elastica:
    clients:
        default: { url: '%env(ELASTICSEARCH_URL)%' }
    indexes:
        example_index:
            properties:
                myProperty:
                    type: keyword
            persistence:
                model: App\Entity\ExampleEntity
                repository: App\SearchRepository\ExampleRepository
                listener: false

// src/SearchRepository/ExampleRepository.php

namespace App\SearchRepository;

use FOS\ElasticaBundle\Repository;

final class ExampleRepository extends Repository
{
}

// src/Entity/ExampleEntity

namespace App\Entity;

final class ExampleEntity
{
    public string $myProperty;
}

// src/Controller/TestController.php

namespace App\Controller;

use FOS\ElasticaBundle\Manager\RepositoryManagerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

final class TestController extends AbstractController
{
    #[Route('/test', name: 'test')]
    public function test(RepositoryManagerInterface $repositoryManager)
    {
        $repository = $repositoryManager->getRepository('example_index');

        $result = $repository->find('*');

        dd($result);
    }
}

When I go to the "/test" route I get the following Exception:

Error:
Call to a member function getRepository() on null

Am I doing something wrong or is there a bug?

[joergmoldenhauer]

The problem could be that I am using the bundle without a database table for my Elasticsearch records. When I add ORM annotations to my entity I get the following error:

Base table or view not found: 1146 Table 'my_database.example_entity' doesn't exist

It seems like the bundle is trying to get the results from a database. Is there a way to use the bundle without storing entries in a database and only storing them in Elasticsearch?
