Fetching attached pages using REST

When getting pages using the REST API is there any way to access the data of attached pages? We have a page type that has a page field but the REST API returns null for that field, even when there is a page populated in that field in the CMS. That field's page can be accessed server-side in MVC using the generated class files, it is only when calling the REST endpoints that the field returns null. All of the more standard/basic fields for stuff like text, number etc are present and populated.

Here is the URL I am attempting this with: https://EXAMPLE.COM/rest/content/currentsite/defaultculture/childrenof/?format=json&classnames=custom.marketingBanner&topn=30&selectonlypublished=true
