error TypeError: Failed to parse URL from undefined/api/graphql?page=home

I'm attempting to setup a Next boilerplate to render blocks - I'm copy/pasting payload-main (Next) files. I'm receiving this error -

error TypeError: Failed to parse URL from undefined/api/graphql?page=home

Do you know how to solve?

Repo:

This is the repo folders, where or what is

undefined/api?

Oh, I think it's because I have the payload-website graphql queries. I think I'm going to remove all of them and go the REST route.
