Error 400: Invalid Request when using Google OAuth2 on Vercel builds (works in localhost)

[SushritPasupuleti]

Describe the bug
I built a basic project using the example repo. Everything is configured (environment variables, authorized domains etc) and even included the environment variables on vercel too. But for some reason, even after it works perfectly on localhost the login fails when on vercel.

Steps to reproduce

• You can head to my live site here: link to site

• Press sign in in the top nav bar.

• Use google sign in

• You're greeted by the error message.

Expected behavior
The signin should be succesful and you should be redirected to the home page. And the nav bar should show your gmail details.

Updating to the latest version fixed this issue, without changing any other configs.

@tamlth0595 sure, let me know what it is ?

[tamlth0595]

ok, I will send you the url.

[tamlth0595]

when I click the "sign in" button, why the url is redirected to the different url?
I am not why this happens.
