hiya!
i have a nextjs 14 app with nextauth v5 set up, but i can't navigate to /auth/route - i get a 404.

i have app/api/auth/[...nextauth]/route.ts created with contents

import { handlers } from "@/auth";  export const { GET, POST } = handlers;

where src/auth.ts is

import NextAuth from "next-auth";
import Google from "next-auth/providers/google";

import type { NextAuthConfig } from "next-auth";

export const config = {
  providers: [Google],
  basePath: "/auth",
  callbacks: {
    jwt({ token, trigger, session }) {
      if (trigger === "update") token.name = session.user.name;
      return token;
    },
  },
} satisfies NextAuthConfig;

export const { handlers, auth, signIn, signOut } = NextAuth(config);

Why is navigating to http://localhost:3000/auth/signin still throwing a 404?

If I call signIn myself, I still get a 404 when the Google auth redirects to
http://localhost:3000/auth/callback/google?code=xxxx...


I'm not using the pages router, i'm using the app router from next 13.
