customized publish sorts – Inside Server Error when echoing an OBJECT from wp ajax motion perform in features.php to JS file


I am utilizing Elementor Professional as my web page builder. I am attempting to create a Job Publish filter utilizing Elementor kinds. Challenge is once I echo and return an Object sort from the features.php file to the JS file. It offers out an Inside Server Error 500. I wish to understand how I can cross the entire publish object as a substitute of sending Title, excerpt, picture individually.

JS code

jQuery(perform($){
    $('#jobs_filter_form').submit(perform(){
        filter = $('#jobs_filter_form');
        let key phrases = $('#form-field-job_keywords').val();
        let location = $('#form-field-job_location').val();
        let class = $('#form-field-job_category').val();
        $.ajax({
            url:'http://localhost/placementpro/wp-admin/admin-ajax.php',
            knowledge:{
                'motion': 'filter_jobs',
                'key phrases': key phrases,
                'location': location,
                'class': class,
            },
            sort:'POST',
            beforeSend:perform(xhr){
                filter.discover('button').textual content('Processing...'); // altering the button label
            },
            success:perform(knowledge){
                filter.discover('button').textual content('Apply filter'); // altering the button label again
                $('#filtered_jobs').html(knowledge);
            },
        });
        return false;
    });
});

PHP code

add_action('wp_ajax_filter_jobs', 'filter_jobs_function');
add_action('wp_ajax_nopriv_filter_jobs', 'filter_jobs_function');

perform filter_jobs_function(){
    $key phrases = $_POST['keywords'];    
    $location = $_POST['location'];    
    $class = $_POST['category'];
        
    $args = array(
        'post_type'         => 'kuwjr_job',
        'cache_results'     => false,
        'update_post_meta_cache' => false,
        'update_post_term_cache' => false,
        'fields'            => 'all',
        'post_status'       => 'publish',
        'posts_per_page'    => 12,
        'orderby'           => 'date',
        'order'             => 'DESC',
        's'                 => $key phrases,
        'meta_query'        => array(
            array(
                'key'   => 'location',
                'worth' => $location,
            ),
        ),
        'tax_query'         => array(
            array(
                'taxonomy'  => 'job-category',
                'phrases'     => $class,
                'subject'     => 'title',
            ),
        ),
    );

    $question = new WP_Query( $args );

    if( $query->have_posts() ):
        whereas( $query->have_posts() ): $query->the_post();
            echo $query->publish;
        endwhile;
        wp_reset_postdata();
    else :
        echo 'No posts discovered';
    endif;

    die();
}
