3. regenerate folder from generated Watcha 4.0 iOS sketch file.
4. find the folder broken (missing document.json)

Expected Behavior

Generated folder from the Sketch file shouldn't be broken.

Actual Behavior

Additional Information

I've shared the repo.

Seems fine when I completely remove the folder from repository and commit, then regenerate new folder from the file(modified in Sketch 50).

I'll report if I get similar error again even though I keep matching sketch version across the team.

But I think there should be some way to notify JSON side effect generated by sketch version upgrade in Kactus. I don't know if it can be solved from Kactus side alone.
