Creating a "CPT Widget" using metabox View

Hello
i'm new to metabox (from toolset) and i have question.
i wanted to create a "widget" using the mb view that shows the "Latest News" from the custom post type "news"
i tried creating view but the url/permalink and the image is showing up empty (only the post_title works)
any suggestion where i did it wrong?
Thank you

{% set news = {post_type: 'news', posts_per_page: 5} %}
{% set newss = mb.get_posts( news ) %}

{% for news in newss %}

    <div class="list_news_page_item">
        <div class="news_cover_image">
            <a href="{{ news.url }}">
            <img src="{{ news.news_cover_image.medium.url }}" width="{{ post.news_cover_image.medium.width }}" height="{{ news.news_cover_image.medium.height }}" alt="{{ news.news_cover_image.medium.alt }}">
            </a>
        </div>            

        <div class="news_title">
            <a href="{{ news.post_url }}">
            {{ news.post_title }}
            </a>
        </div>
    </div>
{% endfor %}
