Behavior difference between Sanity client and vision tool when referencing documents with a modified _id.

Hello all, question regarding the _id of documents. We recently did a migration in sanity and decided we wanted to be able to know the “old” _id by making the new document id be

prefix.old__id

. This works fine however if we reference these documents in a groq query we get results in the vision tool (any setting really) but if we use the sanity client it will return null?!

We managed to resolve the situation by migrating again but this time use

prefix-old_id

curious why the client is behaving differently to the vision tool though (and is there some arbitrary check for a dot that caused this behaviour?).

By adding a prefix with a

.

, you’re creating a non-root path for that document. That means that they’re not considered public and require a token in order to be queried.

Ahhh so silly should have read up on that, thanks for the clarification !

It’s a super easy thing to miss!
