Generator Config

provider:
  name: edgecase

resources:
  map_test:
    create:
      path: /map_test
      method: POST
    read:
      path: /map_test
      method: GET

Expected Behavior

Maps (using the additionalProperties property) should be able to leverage nullable and stringable types

{
  "provider": {
    "name": "edgecase"
  },
  "resources": [
    {
      "name": "map_test",
      "schema": {
        "attributes": [
          {
            "name": "map_stringified",
            "map": {
              "computed_optional_required": "computed_optional",
              "element_type": {
                "string": {}
              },
              "description": "This is a map with a stringifed value"
            }
          }
        ]
      }
    }
  ],
  "version": "0.1"
}

Actual Behavior

The map is returned in the IR output as a single nested attribute with no attributes

{
  "provider": {
    "name": "edgecase"
  },
  "resources": [
    {
      "name": "map_test",
      "schema": {
        "attributes": [
          {
            "name": "map_stringified",
            "single_nested": {
              "computed_optional_required": "computed_optional",
              "description": "This is a map with a stringifed value"
            }
          }
        ]
      }
    }
  ],
  "version": "0.1"
}
