After updating to zod 3.23.8 this issue started appearing for me.
Updating @hookform/resolvers to 3.3.4 does not help.

TypeScript error message:

This issue goes away when downgrading @hookform/resolvers to ^2.0.0

[jorisre]

Can you please provide a minimal reproducible example (e.g. a Codesandbox)?

[matart15]

"@hookform/resolvers": "3.9.0",
"zod": "3.22.4"

results type mismatch

"@hookform/resolvers": "3.9.0",
"zod": "3.23.8"

works.

Question.
Why do you keep separate zod code in this library? it is hard to tell which zod version it is compatible with
https://github.com/react-hook-form/resolvers/blob/master/zod/package.json
https://github.com/react-hook-form/resolvers/blob/master/zod/src/zod.ts

I also encounter this issue with the latest versions of both zod and @hookform/resolvers. Wanted to create a Stackblitz to show the issue, but even with the same versions I can't reproduce it and now I'm confused...

Don't know if this helps, but I could fix this just now by first downgrading @hookform/resolvers to v2 and then upgrading back to latest. So, maybe there is something weird happening during the resolution of dependencies while upgrading anything zod or zodresolver related.

Also have this issue, downgrading did not work:

"react-hook-form": "^7.54.2",
"zod": "^3.24.1"

@rferreira98 Can you please provide a minimal reproducible example (e.g. a Codesandbox)?

[dmfigueroa]

I had this issue and could solve it deduping my dependencies, not sure if everyone else having this issue is also on a monorepo

[rgalaxy]

I also had this issue.

{
  ....
  "@hookform/resolvers": "^5.1.1",
  "react-hook-form": "^7.60.0",
  "zod": "^3.25.76"
}

@jorisre minimal reproducible. https://codesandbox.io/p/sandbox/gfv95j
