I have two resources. The two are related to each other.

Article resource

defmodule Accounts.Blog.Article do
  use Ash.Resource,
    domain: Account.Domain,
    data_layer: AshPostgres.DataLayer,
    extensions: [AshJsonApi.Resource]

  ...
  
actions do
    read :read do  
      pagination countable: true, offset?: true, required?: true, default_limit: 10
    end
  end

  relationships do
    has_many :comments, Comment
  end
end

Comments resource

defmodule Accounts.Blog.Comment do
  use Ash.Resource,
    domain: Account.Domain,
    data_layer: AshPostgres.DataLayer,
    extensions: [AshJsonApi.Resource]

  ...
  
  actions do
   read :read do  
      pagination countable: true, offset?: true, required?: true, default_limit: 10
   end
  end

  relationships do
    belongs_to, :article, Article
  end
end

Domain

defmodule Account.Domain do
  use Ash.Domain, extensions: [AshJsonApi.Domain]

  alias Accounts.Blog.{Article, Comment}
  
  json_api do
    routes do
      base_route "/articles", Article do
        get :read
        related :comments, :read
      end
    end
  end
end

When I try to get the related comments for Accounts.Blog.Article using the endpoint articles/:article_id/comments, the records are not paginated as expected. However, if I make a GET request to /articles, the articles are paginated as expected. Fetching the resource directly works, but pagination does not work for the related resource.
