Hi

I hope I am rephrase my usecase. I have trimmed down for clarity sake. Let’s say that, I have a

defmodule ResourceA do
  ...
  attributes do
    attribute :date
  end
end

ResourceB

defmodule ResourceB do
  ...
  attributes do
    attribute :methods, one_of: [:phone, :online]
  end
end

ResourceC - whose job is get values from ResourceA and ResourceB and return it.

defmodule ResourceC do
  ...
  code_interface do
    define :overlap, args:[...]
  end
  actions do
    action :overlaps, .. do
      argument :start_date, :string, allow_nil?: false
      argument :method, :atom, allow_nil?: false
      run fn input, context -> 
          start_date = inputs.arguments.start_date
          method = inputs.arguments.method
          # gets overlaps from ResourceA and ResourceB
          {:ok, result}
      end
    end
  end
end

Now in the Doamin

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

resources do
 ...
end

json_api do
  routes do
   base_route "/overlaps", ResourceC do 
     route :get, "/overlaps", :overlaps
   end
  end
end
end

I am able to make the call. I can’t pass query params to the api call. I tried to debug but in vain. I am getting 400 error response. Any help is appreciated.

Thanks.
