How to get the Oauth providre access tokens from next auth/authjs

Modify your nextauth client and add a callbacks section that will

• get the access token from the oauth provider
• get the user profile from the oauth provider
• store the access token and user profile in the session
• store the access token and user profile in the token
• modify the jwt payload to include the access token and user profile

import NextAuth from "next-auth";
import GitHub from "next-auth/providers/github";

export const githubScopes = ["user", "repo", "delete_repo"] as const;

export const { handlers, signIn, signOut, auth } = NextAuth({
  pages: {
    signIn: "/auth",
  },
  providers: [
    GitHub({
      authorization: {
        params: {
          scope: githubScopes.slice(0, -2).join(" "),
        },
      },
      //  @ts-expect-error
      async profile(profile) {
      return { ...profile } // get the user oauth profile
    },
    }),
  ],
  debug: true,
  callbacks: {
    jwt: async ({ token, user,account }) => {
      if (account) {
        token.accessToken = account.access_token;
      }
      if (user) {
        token.user = user; // Include the full user profile in the token
      }
      return token;

    },
    session: async ({ session, token }) => {
      // @ts-expect-error
      session.accessToken = token.accessToken; // Include the access token in the session
      // @ts-expect-error
      session.user = token.user;
      return session;

    },
    authorized: async ({ auth }) => {
      // Logged in users are authenticated, otherwise redirect to login page
      return !!auth;
    },
      async redirect({ url, baseUrl }) {
        // redirect to the dashboard if the user is signed in
      return `${baseUrl}/dashboard`;
    },
  },
});

to fix the types create a next-auth.d.ts file

// next-auth.d.ts
import "next-auth";
import { DefaultSession } from "next-auth";

declare module "next-auth" {
  /**
   * Extends the `Session` interface to include custom fields.
   * This is merged with the default `Session` type from NextAuth.js.
   */
  interface Session {
      accessToken?: string;
    user: GithubUser & DefaultSession["user"]; // Merge with default user fields
  }
}

export type GithubUser={
  login: string
  id: string
  node_id: string
  avatar_url: string
  gravatar_id: string
  url: string
  html_url: string
  followers_url: string
    ....other fie;lds
}
