[X] I have written a descriptive issue title
[X] I have searched existing issues to ensure the bug has not already been reported

Fastify version

3.29.0

Plugin version

6.1.1

Node.js version

Operating system

macOS

Operating system version (i.e. 20.04, 11.3, 10)

Description

I have defined my schema for the headers like below.

const headers = {
  $id: "headers",
  type: "object",
  properties: {
    Authorization: { type: "string" },
    "x-country": {
      type: "string",
      transform: ["toUpperCase"],
      enum: ["IN", "US", "CH", "AR", "MX", "UY", "BR"]
    },
    "x-commerce": {
      type: "string",
      description: "Example values: 'FA', 'SO', 'TO' etc"
    }
  }
};

And added in one of my request header like

exports.createProductSizeSchema = {
  tags: ["Product Size"],
  summary: "This API is used to create  Product Sizes",
  description: "productSize should be Unique",
  headers: { $ref: "headers#" }
}

But while generating the definition, enum value is not coming up. PFB the screenshot

Could you please let me know what I am doing wrong here?

Steps to Reproduce

Create a fastify instance and on registering plugins

      description: "API Docs",
      version: "0.1.0"
    },
    servers: [
    ],
    externalDocs: {
      url: "https://swagger.io",
      description: "Find more info here"
    },
    consumes: ["application/json"],
    produces: ["application/json"]
  },
  exposeRoute: true
});
