loadQuery's data is sometimes null

[dvnrsn]

const initial = await context.sanity.loadQuery<Page>(
  PAGE_QUERY,
);

console.log(initial)
// { data: null }

It's not obvious to me why this value is null in the remix loader. Sometimes even in the same moment it is switching. I know it works because the UI looks good but I noticed this because I started seeing server errors.
