Frontmatter File node appears as string in custom resolver

[olivier-lacroix]

Hi there,

I am trying to create a custom resolver by using createResolvers, on a Markdown Frontmatter node (source)

In that resolver, I want to access a child File node (source.document).

The File node appears as such in graphql, but in my custom resolver, it appears as a string only. ie. as defined in the markdown file frontmatter, before conversion into a File node.

How can I access that file field as a File node?

Thx!
