Recursive Schema Causes Type Instantiation Is Excessively Deep or Infinite
Describe the bug
I am using a necessarily recursive schema for a feature to store logic as JSON. We're unable to actually have type validation due to the Type instantiation is excessively deep and possibly infinite error that shows up. I used the most recent zod syntax for the recursive schema as well.
Your minimal, reproducible example
https://stackblitz.com/edit/sveltejs-kit-template-default-vqnfhqkw?file=src%2Froutes%2F%2Bpage.svelte
Steps to reproduce
- Clone the StackBlitz
- Run
npm install - Open the +page.svelte file in your editor
Expected behavior
In my editor, I would like to still see type hints without type errors. I understand that type depth might be limited, but since I am using recursive components I am not actually managing this entirely in the UI.
How often does this bug happen?
