Description

Fastify docs mentioned that you can get the registered handler in onRequest hook by request.routeOptions.hndler, but there handler doesn't exist in the typeof routerOptions

 app.addHook('onRequest', (req, res, done) => {
  // Property 'handler' does not exist on type 'Readonly<RequestRouteOptions<unknown, FastifySchema>>'
    console.log( req.routeOptions.handler);
    done();
  });
};
