Description

The hooks specified in the options of a route no longer have the correct typings applied/resolved. They come back as any. The following code snippet works in 4.15.0, but breaks in 4.16.0

Steps to Reproduce

import Fastify from "fastify";

const fastify = Fastify();

fastify.get(
  "/route",
  {
    onError: (request, reply, error) => {
      request // is any
      reply // is any
      error // is any
    },
  },
  async () => ({ success: "yes" })
);

The same appears to be true for all the other hooks specified in this manner as well.

Interestingly, hooks added with addHook appear to have the correct typings resolved

Expected Behavior

No response
