Original GitHub issue: https://github.com/better-auth/better-auth/issues/6368

Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  • login with google sign in on android emulator
  • it will redirect to google sign page, and comeback to app with sign success
  • now sign out
  • then login again with google, you will see it will not redirect to browser window for google sign in page

Current vs. Expected behavior

Current
In the expo terminal i am getting below error:

 ERROR  OAuth login error: [Error: The WebBrowser's auth session is in an invalid state with a redirect handler set when it should not be]

Expected

It should redirect to browser windows for google sign page

What version of Better Auth are you using?

1.4.3

Which area(s) are affected? (Select all that apply)

Client, Package

Auth config (if applicable)

Additional context

I am using expo@~54.0.23.

I think the issue is that expo-web-browser maintains state between OAuth sessions. When the first OAuth session completes, the redirect handler isn't properly cleaned up, causing the second attempt to fail.

@better-auth-agent[bot] commented on GitHub (Nov 28, 2025):

It appears that the error is coming from expo-web-browser holding on to a previous redirect handler during subsequent OAuth sessions. One troubleshooting step is to ensure that after signing out you are properly dismissing any active auth session—using expo-web-browser’s dismissAuthSession or clearing its cached state—so that a fresh redirect handler is established on the next sign-in attempt [3]. Could you try explicitly resetting the OAuth session between sign-ins and let me know if that resolves the issue? Tag @better-auth-agent if you would like an answer from the Agent.

This bug is in the Android app only, I found an temprory fix by manually redirecting to auth page. Below is the code:

const socialLoginResult = await expoAuthClient.signIn.social({
                provider: "google",
                callbackURL,
                // We will manually handle the browser redirect flow on Android
                disableRedirect: true,
            });

            const authUrl = socialLoginResult?.data?.url;

            if (!authUrl) {
                throw new Error("No auth URL returned from social sign-in");
            }

            const proxyURL = `${expoAuthClient.baseURL}/api/auth/expo-authorization-proxy?authorizationURL=${encodeURIComponent(authUrl)}`;
            const result = await Browser.openAuthSessionAsync(
                proxyURL,
                callbackURL,
            );
