Description
Hi there!
First of all, thanks for the plugin.
I am encountering an error when I'm trying to move out my schema definitions outside of my route plugin. I wanted to move them out to be able to share them in other route plugins but I'm getting this error:
Unable to dereference schema with $id ...
This also happens even when you use fastify-plugin to wrap the plugin that defines the shared schemas.

Expected Behavior
I should be able to define the shared schemas outside of my route plugins and reference them via Type.Ref.
