Hi, I'm trying to deploy a project with the Google Provider (using NextAuth) to Vercel. However, on deployment, I receive this error. I followed a YouTube tutorial, and they didn't state the session type, nor other tutorials I had a quick look at.

Type error: Binding element 'session' implicitly has an 'any' type.

Code

import NextAuth from "next-auth/next";
import GoogleProvider from "next-auth/providers/google";
import { connectDB } from "@/utils/database";
import User from "@/models/user";

const authOptions = {
  providers: [
    GoogleProvider({
      clientId: process.env.GOOGLE_CLIENT_ID as string,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET as string,
    }),
  ],
  callbacks: {
    async session({ session }) {
      console.log(session);
      const sessionUser = await User.findOne({
        email: session.user.email,
      });
      console.log(sessionUser);
      session.user = {
        name: sessionUser?.name,
        _id: sessionUser._id,
        username: sessionUser.username,
        email: sessionUser.email,
      };

      return session;
    },
   secret: process.env.NEXTAUTH_SECRET as string,
}

const handler = NextAuth(authOptions);
export { handler as GET, handler as POST };
