I've generated a serverless project using the toolbox. what does this code do?

object ExampleAppLoader : AppLoader {
    override fun invoke(env: Map<String, String>): HttpHandler {
        val client = PrintResponse()
            .then(ClientFilters.SetBaseUriFrom(Uri.of("<https://pokeapi.co/api/v2/pokemon>")))
            .then(JavaHttpClient())

        return PrintRequest()
            .then(
                routes(
                    "/pokemon" bind client,
.
.
.
                )
            )
    }
}

Initially I thought, if I call my lambda using GET /pokemon, it will call GET https://pokeapi.co/api/v2/pokemon. If I call GET /pokemon/bulbasaur, it will call https://pokeapi.co/api/v2/pokemon/bulbasaur. but I tried to run it locally:

fun main() {
    fun runLambdaLocally() {
        val app: HttpHandler = ExampleAppLoader(mapOf())
        val localLambda = app.asServer(SunHttp(8000)).start()
        val response = JavaHttpClient()(
            Request(
                GET,
                "<http://localhost:8000/pokemon>"
            )
        )

        println(response)
        localLambda.stop()
    }
    runLambdaLocally()
}

it's returning 404 error
