Duplicating content in Sanity Studio v3.40.0 causes reference issues

🧵 Curious if this is a known bug - using studio v

3.40.0

PEBKAC

Duplicating content in an array using the default "Duplicate" option does some interesting things.
If you duplicate an object, then edit a field in one instance - all other fields get updated.

Kinda looks like the duplicated content receives the same id.

Heres a barebones query showing the id issue, which is what I think this stems from.

From your query it looks like cards are references, so you’re duplicating the card but it’s pointing at the same document.

Ahh gotcha

That makes total sense - I was hitting a wall here. 🤦Thanks
😆

I think what you’ll need to do is:
1. Open the referenced document.
2. Duplicate it from the menu in the bottom-left.
3. [Make changes now or later]
4. Go back to the source document.
5. Change the reference to point at the new document.

All good!
