create a new class, including those instances, and write the new class

official examples are directly returned to schema without a package key, ignoring that you can wrap it with object. The problem has been resolved, and the code is as follows

"get": {
  "tags": [
    "option_types"
    ],
  "responses": {
    "200": {
    "description": "optionType: {}; OptionValues: []",
    "schema": {
      "type": "object",
      "properties": {
        "option_type": {
          "$ref": "-sharp/definitions/OptionType"
          },
        "option_values": {
          "type": "array",
          "items": {
            "$ref": "-sharp/definitions/OptionValue"
            }
          }
        }
      }
    }
  }
}
