I'm using the Stock Photo Search module, for particular image fields, and it has its own field type with interesting properties.

As far as I can tell, the only way to access the URI of the image is content.field_stock_photo[0]['#uri']. There is no node.field_stock_photo.0.entity.uri.value or similar. The only way to access the URI is through the rendered entity.

The problem I'm running into is when using a reference, I have no way to access this rendered entity from a reference. node.reference.0.entity.field_stock_photo.value doesn't do it, and as far as I can tell node.reference.0.content.field_stock_photo doesn't work.

How do I go about getting properties from a rendered entity of a reference in Twig?
