import DiscordProvider from "next-auth/providers/discord"

import { env } from "@/env.mjs"
import { db } from "@/lib/db"

const scopes = ["identify", "guilds", "email"].join(" ")

export const authOptions: NextAuthOptions = {

      authorization: { params: { scope: scopes } },
    }),
  ],
  callbacks: {
    async session({ token, session }) {
      if (token) {
        session.user.id = token.id
