How do I redirect properly?

"use server";

import {
    GoogleAuthProvider,
    signInAnonymously,
    signInWithPopup,
} from "firebase/auth";
import { auth } from "./client-firebase";
import { createUserSession } from "./session";
import { redirect } from "@solidjs/router";

const googleProvider = new GoogleAuthProvider();

export const signInWithGoogle = async () => {
    try {
        const userCredential = await signInWithPopup(auth, googleProvider);
        console.log("Signed in with Google:", userCredential.user);

        const token = await userCredential.user.getIdToken();
        await createUserSession(token);
    } catch (error) {
        console.error("Error signing in with Google:", error);
        throw error;
    }
};

export const signInAsAGuest = async (event) => {
    try {
        const userCredential = await signInAnonymously(auth);
        const token = await userCredential.user.getIdToken();
        const user = await createUserSession(token);
        if (user) throw redirect("/in");
    } catch (error) {
        console.error("Error signing in as guest:", error);
        throw error;
    }
};
