Too Many Redirects when change authentication to better-auth

[luisalbuquerque00]

Describe the bug
I switched the authentication method from Clerk to Better-Auth, and whenever I try to access the sign-in/sign-up page, I get the error message "too many redirects."

I believe the problem lies in this section of the code:

// auth/proxy.ts

if (!sessionCookie) {
  return NextResponse.redirect(new URL("/sign-in", request.url));
}

next-forge version
I am using version 5.3.2

To Reproduce
Steps to reproduce the behavior:

1. Change Clerk to Better-Auth
2. Clear cookies
3. Go to sign-in page
4. Error too many redirect trigged
5. See error

Expected behavior
Switching the authentication method should work exactly as it does when using Clerk as the authentication provider.
