Extending the Session not working (Credentials Providers)

[nicolas-atls]

Hello, i cannot add any extra information to my user session... any idea what's wrong ?
I use the latest version of auth.js: "next-auth": "5.0.0-beta.20",

Here is my code, and authorise is well triggered when i call the signIn function
Inside the callbacks and in session() and jwt() user is undefined... i cannot add it to the session, as you can see on the code below i would like to add the properties "uid"

const { handlers, signIn, signOut, auth } = NextAuth({
  pages: {
    signIn: "/auth",
  },
  session: {
    strategy: "jwt",
    // maxAge: 30 * 24 * 60 * 60, // 30 days
  },
  callbacks: {
    jwt(props) {
      const { token, user } = props;
      if (user) {
        // token.id = user.id;
        // token.role = user.role || "user"; // Add any other properties you need
      }
      return token;
    },
    session(props) {
      const { session, user, token } = props;
      return {
        ...session,
        user: {
          ...session.user,
        },
      };
    },
  },
  providers: [
    Credentials({
      credentials: {
        email: {},
        password: {},
      },
      authorize: (credentials) => {
        let user = null;
        user = {
          name: "John Doe",
          email: "[email protected]",
          uid: "aaa1234567890aaa",
        };
        if (!user) {
          throw new Error("User Not Found");
        }
        return user;
      },
    }),
  ],
}); 

I also create the next-auth.d.ts file in the types directory at the root of the project

import NextAuth, { DefaultSession, DefaultUser } from "next-auth";
import { JWT, DefaultJWT } from "next-auth/jwt";

declare module "next-auth" {
  /**
   * Returned by `useSession`, `getSession` and received as a prop on the `SessionProvider` React Context
   */
  interface Session {
    user: {
      uid: string;
    } & DefaultSession["user"];
  }

  interface User extends DefaultUser {
    uid: string;
  }
}


declare module "next-auth/jwt" {
  interface JWT {
    uid: string;
  }
}

any idea please why email and name are ok but no uid ?

🚀 ~ jwt ~ token: {
  name: 'John Doe',
  email: '[email protected]',
  sub: '2a2f53e5-4389-48b2-a8b7-e4a0c3eebb7c',
  iat: 1723207035,
  exp: 1725799035,
  jti: '7ba737eb-81ef-4d01-a39a-b3ad58fad7d9'
}
