Issue with running `sanity deploy` after upgrading to V3, error related to missing sanity.json file.

Hi all, I've had an issue appear after upgrading to V3. I can't run

sanity deploy

(or

configcheck

) as the following error is returned...

Error: ENOENT: no such file or directory, open '/Users/marks/client-work/surf-simply/surf-simply/studio/sanity.json'

Obviously

sanity.json

haas been removed in favour of

sanity.config.js

so I'm not sure what's looking for that file. Studio is working perfectly locally.
here is the following console warning when running locally...

`Both

@sanity/core

AND

sanity

installed - assuming Sanity v3 project.`
I can't find any reference to

@sanity/core

anywhere in my project though. So, yeah, weird one. V2 to V3 upgrade.
Any help would be really amazing... thank you
🙏

This is probably a long shot but have you tried removing

node_modules

and reinstalling?

Have you also upgraded your CLI to the latest version?

Thank you so much, back up and running! 🙂

Awesome! Good luck with the rest of your migration!

So I just wanted to follow up with a more macro thank you... you're always so helpful and just make working with dream software like Sanity all the more dreamy. Props to you and the rest of the Sanity team for not only making the best product around but also a community to match. 👊

Thank you, User! That means a lot!
