I’m unable to display the featured image for the metaobject fields corresponding to either single product or single variant. However, I can successfully retrieve the featured images from the list versions of both product and variant fields. Here’s the working loop for the list version:

{% for addon in shop.metaobjects.addons.values %}         
    {% for product in addon.test.value %}           
        {{ product.featured_image | img_tag }}         
    {% endfor %} 
{% endfor %} 

In contrast, the loop for the single version is not functioning:

{% for addon in shop.metaobjects.addons.values %}         
    {% for product in addon.variant.value %}           
        {{ product.featured_image | img_tag -}}         
    {% endfor %}       
{% endfor %} 

For context, here is an example of the metaobject illustrating the Name key for the fields:

And here’s a populated example of the metaobject:

I’m expecting to get the featured image instead of a “no image” image.
