Using plugins MultivendorX + Woocommerce, I’m trying to get a random list of vendors (avatar, name, rating).

The problem with getting a vendor avatar is that the line of code

$image = $vendor->get_image() ? $vendor->get_image('image', array(125, 125)) : $MVX->plugin_url . 'assets/images/WP-stdavatar.png';

breaks any page where the shortcode [random_vendors] is displayed.

The code I’m using:

function random_vendors_shortcode() {
    if ( is_tax( 'dc_vendor_shop' ) ) {
    $current_taxonomy = get_queried_object();
    $taxonomies = get_terms(array(
        'taxonomy' => 'dc_vendor_shop',
        'number' => 10,
        'orderby' => 'rand',
    ));
    $output = '<ul class="container random-vendors">';
    foreach ($taxonomies as $taxonomy) {
        if ($taxonomy->term_id == $current_taxonomy->term_id) {
            continue; 
        }
        $vendor = get_mvx_vendor($taxonomy->term_id);
        $image = $vendor->get_image() ? $vendor->get_image('image', array(125, 125)) : $MVX->plugin_url . 'assets/images/WP-stdavatar.png';
        $rating_info = mvx_get_vendor_review_info($taxonomy->term_id);
        $rating = round($rating_info['avg_rating'], 2);
        $review_count = isset($rating_info['total_rating']) ? intval($rating_info['total_rating']) : 0;
        $output .= '<li>';
        $output .= '<div class="random-vendor">';
        $output .= '<a href="' . get_term_link($taxonomy) . '">' . $taxonomy->name . '</a>';
        $output .= '<div class="vendor-image">';
        $output .= '<img src="'. $image .'" alt="'. $taxonomy->name .'">';
        $output .= '</div>';
        $output .= '<div class="mvx_vendor_rating">';
        if ($rating > 0) {
            $output .= '<div class="star-rating"><span style="width:'.(($rating / 5) * 100).'%"><strong itemprop="ratingValue" class="ratingvp">'.$rating.'</strong> из 5  </span></div>';
        } else {
            $output .= '<div itemprop="ratingValue" class="star-rating"></div>';
        }
        $output .= '</div>';
        $output .= '</div>';
        $output .= '</li>';
    }
    $output .= '</ul>';
    return $output;
}
}
add_shortcode('random_vendors', 'random_vendors_shortcode');

Any help please
