Expected Behavior

When generating a response example, any attributes with a negative number should be included in the generated openapi spec.
Example code:

  interface User {

    id: number;
    email: string;
    name: string;
    status?: "Happy" | "Sad";
    phoneNumbers: string[];
  }
  
  @Route("users")
  export class UsersController extends Controller {
    @Example<User>({
      id: -1,
      email: "[email protected]",
      name: "Jimmy",
      phoneNumbers: ["778-234-5678"]
    })
    @Get("{userId}")
    public async getUser(
      @Path() userId: number,
      @Query() name?: string
    ): Promise<User> {
      return new UsersService().get(userId, name);
    }

should produce a swagger doc containing:

"responses": {
   				"200": {
   					"description": "Ok",
   					"content": {
   						"application/json": {
   							"schema": {
   								"$ref": "#/components/schemas/User"
   							},
   							"examples": {
   								"Example 1": {
   									"value": {
   										"id": -1,
   										"email": "[email protected]",
   										"name": "Jimmy",
   										"phoneNumbers": [
   											"778-234-5678"
   										]
   
 }

Current Behavior

Instead, the attribute with a negative number is not included in the openapi spec. The example code above produces:

"responses": {
					"200": {
						"description": "Ok",
						"content": {
							"application/json": {
								"schema": {
									"$ref": "#/components/schemas/User"
								},
								"examples": {
									"Example 1": {
										"value": {
											"email": "[email protected]",
											"name": "Jimmy",
											"phoneNumbers": [
												"778-234-5678"
											]
