Help with Block Bindings

I’ve created an image custom field featured_image in a taxonomy pod and want to display it on the site.

This shortcode works as expected:

[pods]{@featured_image._img}[/pods]

However, the image isn’t responsive and doesn’t respect the parent block’s settings.

I want to use the core image block with block binding to better control dimensions, set a border radius, etc. This code does NOT work:

<!-- wp:image {
    "metadata": {
        "bindings": {
            "url": {
                "source": "pods/bindings-field",
                "args": {
                    "field": "featured_image"
                }
            }
        }
    }
} -->
<figure class="wp-block-image">
    <img src="" />
</figure>
<!-- /wp:image -->

The image block doesn’t render in the frontend. Is there something I’m doing wrong?

The site is running WP 6.7.1 with 2025 theme and the latest version of Pods.
