What warning "does not have an input type defined" means for embedded resources?

I have this resource in my code:

defmodule Core.Marketplace.Payments.Product.Types.Test do
  @moduledoc false

  use Ash.Resource,
    data_layer: :embedded,
    extensions: [AshGraphql.Resource]

  attributes do
    timestamps(public?: true)
  end

  graphql do
    type :payments_product_test
  end
end

And I use it in this type:

defmodule Core.Marketplace.Payments.Product.Types.Metadata do
  @moduledoc false

  alias Core.Marketplace.Payments.Product.Types

  use AshGraphql.Type

  use Ash.Type.NewType,
    subtype_of: :union,
    constraints: [
      types: [
        ...,
        test: [type: Types.Test, tag: :type, tag_value: :test]
      ]
    ]

  @impl true
  def graphql_type(_), do: :payments_product_metadata
end

When I compile this, I get this warning:

warning: Embedded type Core.Marketplace.Payments.Product.Types.Test does not have an input type defined, but is accepted as input in at least one location.

What does this means?

Its telling you to add an input type

 @impl true
  def graphql_type(_), do: :payments_product_metadata
  def graphql_type(_), do: :payments_product_metadata_input

But is not the Metadata type that doesn’t have an input, is the Test resource.

I don’t see a way to set the input type in the AshGraphql.Resource DSL.

Also, from the code above, I guess you meant:

  @impl true
  def graphql_type(_), do: :payments_product_metadata
  def graphql_input_type(_), do: :payments_product_metadata_input

Oh, right :thinking: interesting. Can you create a reproduction and open an issue? It may be a spurious warning.
