zod

1. Found behind latest

   Oct 26, 02:10 UTC

   zod 3.25.76 is declared in package.json; the registry's latest is 4.1.12.

2. Compared the release's API

   Zod 4 drops the required_error and invalid_type_error parameters in favour of a single error parameter. Verified against the package's declarations and the Zod 4 migration guide.

   Candidate	Result	Reason
   4.1.12	Verified	Independently verified

3. Zod: required_error and invalid_type_error replaced by error

   Schema constructors take one error parameter; the two specialised message parameters are dropped.

   − z.string({ required_error: "Required" })

   + z.string({ error: "Required" })

   Evidence: Declarations at 4.1.12 (v4/core/params.d.ts) · Migration guide (zod.dev/v4/changelog · "drops invalid_type_error and required_error")

4. Rewrote 2 call sites

   lib/forms/signup.ts:8

   − z.string({ required_error: "Email is required" })

   + z.string({ error: "Email is required" })

   lib/forms/billing.ts:15

   − z.number({ invalid_type_error: "Enter an amount" })

   + z.number({ error: "Enter an amount" })

5. Validated with 684 tests

   Each check ran on the unmodified repository first; only checks that pass there judge the change. One repair attempt ran after the first failure.

   Check	From	Unmodified	With change	Tests
   pnpm test	ci.yml · unit	Passed	Passed	684

   Already failing before the change, so not counted against it: pnpm test:e2e

6. Review gate approved the patch

   Messages preserved verbatim. One informed retry fixed a missed schema in lib/forms/address.ts.
