Custom Search Function in WordPress Returns No Results

Here’s the right code I made a mistake with s param

function custom_search_query($query) {
    if (!is_admin() && $query->is_main_query() && $query->is_search()) {
        $search_query = get_search_query();  // Retrieve the search query
        $api_url="https://api.adenwalla.in/api/search/data";
        $args = array(
            'body' => json_encode(array('query' => $search_query)),
            'headers' => array('Content-Type' => 'application/json'),
            'timeout' => 60
        );

        $response = wp_remote_post($api_url, $args);
        $body = wp_remote_retrieve_body($response);
        $results = json_decode($body, true);

        if (isset($results['ids']) && is_array($results['ids'])) {
            $query->set('post__in', $results['ids']);
            $query->set('orderby', 'post__in');
            $query->set('posts_per_page', -1);
            $query->set('s', '');
        }
    }
}
add_action('pre_get_posts', 'custom_search_query');
