Struggling with ModuleClass in generated open api schema

[morhidi]

Hi Folks, I'm trying to generate a schema that contains classes from an imported package:

import "package://pkg.pkl-lang.org/pkl-pantry/[email protected]#/SchemaGenerator.pkl"
import "package://pkg.pkl-lang.org/pkl-k8s/[email protected]#/api/core/v1/PodTemplateSpec.pkl"

class Test{
  name: String
  podTemplate: PodTemplateSpec
}

output = SchemaGenerator.generate(Test).output

pkl eval gives me the following output:

{
  "type": "object",
  "title": "Test",
  "properties": {
    "name": {
      "type": "string"
    },
    "podTemplate": {
      "type": "object",
      "title": "ModuleClass",
      "properties": {
        "metadata": {
          "type": "object",
          "title": "ModuleClass",
          "description": "Standard object's metadata.\n\nMore info: <https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata>",
          "properties": {
            "generation": {
              "type": "integer",
              "description": "A sequence number representing a specific generation of the desired state.\n\nPopulated by the system.\nRead-only.",
              "nullable": true

This makes the generated schema useless. I expected the podTemplate type to be PodTemplateSpec instead of "object". Any ideas for a solution?
