#primaryimage schema and data URIs

Hello,

I would like to know if it’s possible to remove the #primaryimage schema when no featured image has been set?

I am asking because I have some pages without featured images and the Yoast SEO plugin then seems to take the first image url as #primaryimage, which is in my case a placeholder data URI, which will be replaced by lazy loading.

The schema graph contains this data URI:

`{“@type”:”ImageObject”,”@id”:”https://www.domain.com/#primaryimage”,”url”:”data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAC0lEQVR4nGNgAAIAAAUAAXpeqz8=”}

It would be handy if the plugin could ignore such data URIs.

Best regards
Manuel
