Types for cart.lines not generated

query Input {
  deliveryCustomization {
    metafield(namespace: "$app:checkout-delivery-by-product-data", key: "function-configuration") {
      value
    }

  cart {
    lines {
      cost {

          amount

    deliveryGroups {
      deliveryOptions {
        title

    }
  }
}

IDE output:

It works fine if I change query_path and schema_path to like this: (Note missing ./ before file name)

generate_types!(
    query_path = "input.graphql",
    schema_path = "schema.graphql"
);

Start at the generate_types! entry point and reproduce the issue with the shown query and schema paths, comparing paths with and without the leading ./ . Trace how those arguments resolve the GraphQL inputs; done when the cart.lines types are generated correctly for the documented paths.
