After implementing Google OAuth authentication using Realm Web SDK, some users experience a blank page after completing the Google authentication flow. The callback URL contains authentication tokens but the page fails to process them properly.
here is URL looks like:
https://site.com/auth/callback#baas_client_app_id=APPID&_baas_state=icoqhrkxfdfbftb&_baas_ua=[long JWT token]
and my callback page code is
"use client";
import { useEffect } from "react";
import { useRouter } from "next/navigation";
import { handleAuthRedirect } from "realm-web";
import { useUser } from "@/app/context/UserContext";
export default function AuthCallback() {
const router = useRouter();
const { setUser } = useUser();
useEffect(() => {
const handleCallback = async () => {
try {
handleAuthRedirect();
} catch (error) {
console.error("Auth callback error:", error);
router.push("/?error=auth_failed");
}
};
handleCallback();
}, [router, setUser]);
return null;
}
Expected Behavior
- After Google authentication completes, the user should be redirected to the application
- The authentication tokens should be properly processed
- The user’s session should be established
Actual Behavior
- Some users see a blank page after Google authentication
- The callback URL contains authentication tokens but they’re not being processed
- No error messages are shown to the user
Attempted Solution
I’ve tried implementing a more robust callback handler:
Questions
- Is there a recommended way to handle Google OAuth callbacks with the Realm Web SDK?
- How can we ensure the authentication tokens are properly processed in the callback?
- Are there any known issues with the
handleAuthRedirect
function? - What’s the best practice for handling race conditions during the OAuth callback process?
Any help or guidance would be greatly appreciated. Thank you!
