base path not resolving correctly

My server is running on port 8080 and client on 5173, I have created server auth instance by providing it basePath as "/auth" and created a route "/auth/*".
For authClient instance i have provide full baseUrl as http://localhost:8080/auth.
When i signin with google it sets the cookie but redirects to localhost:8080/auth. what is wrong here?
Solution
I'm using express, and my baseURL in createAuthClient was 'http://localhost:3000' without a '/auth' in front of it. Another issue you might have is that you have to set the callback URL to a full URL. i.e.

  const { error } = await authClient.signIn.social(
      {
        provider: 'google',
        callbackURL: 'http://localhost:5173/home',
        newUserCallbackURL: 'http://localhost:5173/home',
      },
      {
        onError: (error) => {
          console.error(error);
        },
      },
    );


instead of just

callbackURL: '/home'


Not sure if this is helpful, but I had a similar issue and that's what worked for me.
