Had to add this to my .pnpmfile.cjs to override the transitive deps. You can't import zod if its not in your dependencies! Believe it or not this is the second time I am encountering this problem. PR here: https://github.com/react-hook-form/resolvers/pull/765

function readPackage(pkg) {
  if (pkg.name === "@hookform/resolvers") {
    pkg.dependencies = {
      ...pkg.dependencies,
      zod: "^4.0.0",
    };
  }

  return pkg;
}

module.exports = {
  hooks: {
    readPackage,
  },
};

This randomly became an issue for me when everything was working fine before? The .pnpmfile hack didn't work for me :(

I'm also having issues randomly 😓 It was working right before I did an update. The .pnpmfile also didn't work for me.

Edit: I am so confused, turns out the pnpm hack did work 😖 but it broke again LOL

The same issue occurs in Yarn PnP. I tested this with zod 4.1.13 and @hookform/resolvers 5.2.2.

Cannot find module 'zod/v4/core' from ....
