Next.js 13.4 and NextAuth Type Error: 'AuthOptions' is not assignable to type 'never'
Okay i solved it myself. For anyone having the same issue, i created a new file @/utils/authOptions.ts:
import { NextAuthOptions } from "next-auth";
import DiscordProvider from "next-auth/providers/discord";

export const authOptions: NextAuthOptions = {
    providers: [
        DiscordProvider({
            clientId: process.env.CLIENT_ID as string,
            clientSecret: process.env.CLIENT_SECRET as string,
        }),
    ],
    session: {
        strategy: "jwt",
    },
    secret: process.env.NEXTAUTH_SECRET,
}

and used it in @/api/auth/[...nextauth]/route.ts:
import { authOptions } from "@/utils/authOptions";
import NextAuth from "next-auth/next";

const handler = NextAuth(authOptions);

export { handler as GET, handler as POST };

I changed the imports a little (import NextAuth from "next-auth/next")
I dont know why this works tbh, but it does... even changing the imports around in my route.ts as it was before wont fix it. Only if its seperated like that...

I'm currently working on a Next.js 13.4 project and trying to set up NextAuth using the app/ router. However, I'm encountering a type error that I can't seem to resolve.
Here's my route.ts file:
import NextAuth, { AuthOptions } from "next-auth";
import DiscordProvider from "next-auth/providers/discord";

export const authOptions: AuthOptions = {
  providers: [
    DiscordProvider({
      clientId: process.env.CLIENT_ID as string,
      clientSecret: process.env.CLIENT_SECRET as string,
    }),
  ],
  session: {
    strategy: "jwt",
  },
  secret: process.env.NEXTAUTH_SECRET,
}

const handler = NextAuth(authOptions);

export { handler as GET, handler as POST }

And here's the error message when running 'npm run build':
- info Linting and checking validity of types ...Failed to compile.

.next/types/app/api/auth/[...nextauth]/route.ts:8:13
Type error: Type 'OmitWithTag<typeof import("C:/Users/Luk/Documents/Workspace/zerotwo-dash/src/app/api/auth/[...nextauth]/route"), "GET" | "POST" | "HEAD" | "OPTIONS" | "PUT" | "DELETE" | "PATCH" | "config" | ... 6 more ... | "runtime", "">' does not satisfy the constraint '{ [x: string]: never; }'.

I really have no idea whats happening here... when looking up the 'AuthOptions' on t he github page from nextauth i see nothing wrong with my code..
I would appreciate any insights or suggestions on how to resolve this issue. Thanks in advance!
