object not found. How to handle it elegantly?

Dear,

i find this pattern very useful. However, it introduce a new issue on our side.

Let's take as running example the one in this repo.

Before, the entire person was loaded in the person resolver. Now, making use of the dataloader the person is loaded in the subfields.
It may happen that a given person does not exist in the database and this is recognized only in the subfields.

Which is the correct output in your opinion?
- nullify only the given person (but return other if requested) and return null for the person not found (return an error / not return error)
- nullify all the query
- other proposals?
Thanks

Start with the person resolver and the subfields where missing database records are detected. Clarify the intended GraphQL behavior for a missing person, including whether to return partial data or errors; the issue is complete only after that behavior is agreed and implemented or documented.
