code and code verifier issue in documentation

Hey!
I am using auth with Google using nextjs so according to your documentation, there is just only a need for code return in the URL query parameter by Google. But I was continuously facing the issue of invalid codeVerifier and code and codeVerifier can't be empty. In your documentation, there is nothing mention about the codeVerifier.

I have run the code by generating the code verifier manually, let's chat to discuss this in detail.

Thanks
