What is the proper way to "gradually" use withRelay ?

[MoOx]

In short:

I am starting to use relay-next.js on a project but not all pages use withRelay call.
When it's not used, I am having all kind of issues related to the environnement not being setup etc.
But on the pages where withRelay is not used, obviously nothing is properly setup. But I guess changes made (following the docs) on _app and _document expect some data that are not here and thus create weird situation like

TypeError: Invalid value used as weak map key

Am I missing something to properly setup app/document to be able to gradually use withRelay ?

Ref zth/rescript-relay#354

I was a configuration issue. Solved by reviewing everything in the first place (based on vercel/next.js#33892)

relay-nextjs should work gradually and not require using Relay on all pages, however the configuration must always be placed in _app and _document because even though the page doesn't use relay-nextjs, a component that it renders might run useLazyLoadQuery.
