How to customize 404 NotFound handler?

Use the notFoundHandler parameter of UndertowSharafServer:

val customNotFoundHandler: SharafHandler = _ =>
  Response.withBody("Page not found")
    .withStatus(StatusCode.NotFound)

val server = UndertowSharafServer(
    "localhost",
    port,
    routes,
    notFoundHandler = customNotFoundHandler
  )

The handler receives a RequestContext if the response depends on the request.
