I'm working on wpgraphql2.1.0 with acf6 and WPGraphQL for ACF 2.4.1 and I need to get a content type named "evenement" (that we'll call events) that I filter based on their date.

The filtering part is done and works well, I get events based on the field date_de_debut (translated to start_date) which are located in a repeater field dates

I got it working based on this tutorial

    add_filter('graphql_post_object_connection_query_args', function ($query_args, $source, $args, $context, $info) {

    if($args['where']['futur']) {
        $date = date('Ymd');
        $query_args['meta_query'] = [
            [ // si une des deux condition est respectée
                array(
                    'relation' => 'OR',
                    array( // if start_date in the future AND no end_date
                        'relation' => 'AND',
                        array(
                            'key'     => 'dates_$_date_de_debut',
                            'value'   => $date,
                            'compare' => '>=',
                        ),
                        array(
                            'key'     => 'dates_$_date_de_fin',
                            'compare' => 'NOT EXISTS',
                        ),
                    ),
                    array( // if start_date OR end_date in the future
                        'relation' => 'OR',
                        array(
                            'key'    => 'dates_$_date_de_debut',
                            'compare'   => '>=',
                            'value'   => $date,
                        ),

                        array(
                            'key'       => 'dates_$_date_de_fin',
                            'compare'   => '>=',
                            'value'   => $date,
                        ),
                    ),
                ),
            ]
        ];
    }

    return $query_args;
}, 10, 5);

Now what I would like to do but struggle to get working is a way to duplicate each of my returned events based on their dates in the repeater field

What I currently have :

{
          "title": "Event1",
          "fieldsEvenement": {
            "dates": [
              {
                "dateDeDebut": "2025-03-20T00:00:00+00:00",
                "dateDeFin": null,
              },
              {
                "dateDeDebut": "2025-03-21T00:00:00+00:00",
                "dateDeFin": "2025-03-26T00:00:00+00:00",
              }
            ]
          }
        }

What I would like :

{
          "title": "Event1",
          "fieldsEvenement": {
            "dates": [
              {
                "dateDeDebut": "2025-03-20T00:00:00+00:00",
                "dateDeFin": null,
              }
            ]
          }
        }

{
          "title": "Event1",
          "fieldsEvenement": {
            "dates": [
              {
                "dateDeDebut": "2025-03-21T00:00:00+00:00",
                "dateDeFin": "2025-03-26T00:00:00+00:00",
              }
            ]
          }
        }
