• line 410 union error changes to errors

Hi @madhav2348 ! Thanks for working on this. From the tests, looks like the zod update in package.json itself isn't part of the PR?

My apologies, Thank you for figuring out. I was trying to reproduce the failed test case by switching back and forth between Zod 3 and Zod 4 versions to confirm which leads to uncommitted package.json changes.

Thanks for taking this on! Are the changed property names and error types due to the originals no longer existing in zod 4? Just for my own understanding, did you come across any docs explaining those differences?

I went through the migration docs, but they haven't covered all the changes. The changes I made are by going through the source code of Zod 4. Please let me know if further adjustments are needed!

Thank you
