How to throw 404 error with some custom data fields

[engp8691]

I would like to ask gurus here. I has a router which looks for a user. If it does not find the user, it throws a 404 error with a message. That is no problem. But if I want to throw an error as an object. It does not work

{
statusCode: 404,
name: 'LookForUser',
internalCode: 'E610014',
correlationId: '00-905e24caee8691b74be2c3ae6d50178c-d38df853b95a5868-00'
}

If i change the statusCode to 400 or 40x but not 404, it work.

This is my codes

import routes from './constatnt'
import { Schema, schema } from './schema'

server.route<Schema>({
    method: routes.method,
    url: routes.url,
    schema,
    errorHandler: (error, request, reply) => {
      server.errorHandler({ ...error }, request, reply)
    },
    handler: async (request, reply) => {
      try {
        const user = await clients.authService.checkUser(request.body?.userDetails)
        reply.send(user)
      } catch (e) {

      throw ({
      statusCode: 404,
        name: 'LookForUser',
        internalCode: 'E610014',
        correlationId: '00-905e24caee8691b74be2c3ae6d50178c-d38df853b95a5868-00'
      })
      }
    }

Thanks!

      The not found handler is triggered when no route matches, you need to return a 404 manually inside your route if a user cannot be found.

You can simply do a reply.code(404).send( { ... })
