I’m using firebase auth provider (email/password) option with next-auth v4 in my next.js project. What I want to do is access the JWT token from the session on my client using the useSession() hook. this is my authorize function:

CredentialsProvider({
            name: 'Credentials',
            credentials: {
                email: { label: "Email", type: "text", placeholder: "[email protected]" },
                password: { label: "Password", type: "password", placeholder: "*******" }
            },

            async authorize(credentials, req) {
                console.log("attempting to authorize creds");
                try {
                    const userCredential = await signInWithEmailAndPassword(
                        auth,
                        credentials?.email as string,
                        credentials?.password as string,
                    );
                    console.log(userCredential.user.uid);
                    const token = await userCredential.user.getIdToken();
                    console.log(token);

                    const user: MyUser = {
                        id: userCredential.user.uid,
                        email: userCredential.user.email,
                        token: token

                    };
                    const sendUser = { id: userCredential.user.uid, ...userCredential.user, token: token }
                    return sendUser;

                } catch (error) {
                    console.log("Invalid credentials.")
                    return null;
                }
            }
        })

But upon doing this, I am only getting the email field and not the id and token. I verified this by adding the token in the email field and indeed I was getting the token in the email field but there was no token or id field. I should’ve gotten something like

{
    "id" : 1234,
    "email:"[email protected]",
    "token": "ASDasdasFMASFasf123ad"
}

however, I only get this:

{
    "email:"[email protected]"  
}
