ErroCustom.ts

export default class ErrorCustom {
    constructor(public message: string, public code: number){
        this.message = message
        this.code = code
    }
}

route.ts

import ErrorCustom from './ErrorCustom.ts'

router.post('example', async (request, reply) => {
  try{
    const users = await Users.findMany()
    if(!users) throw new ErrorCustom("Couldn't find any users", 404)
  } catch (error) {
    if(error instanceof ErrorCustom){
      return reply.status(error.code).send({
        status: false,
        message: error.message
      })
    }
  }
}
