Redirect after Password reset not working for UL

I am trying to redirect to a url after the change password.
In the FAQ, if I use “Authentication API /change_password endpoint”, then I would need to define the redirect url inside “Application Login URI”

I have defined “Application Login URI” and used the endpoint to have an email sent to the user. But after successfully changing password, it does not get redirected to anywhere.

How can I solve this?

Thanks!

I figured out that my resultUrl is null. How can I configure this?
