Steps to reproduce

z.coerce.date() infers input as unknown and output as Date, causing TS error in react-hook-form:

Type 'unknown' is not assignable to type 'Date | null | undefined'

when i do this i get error bellow

const schema = z.object({
  start_date: z.coerce.date().optional(),
});

useForm({
  resolver: zodResolver(schema),
});

full error

Type 'Resolver<{ start_date?: unknown; }, any, { start_date?: Date | undefined; }>' is not assignable to type 'Resolver<{ start_date?: Date | undefined; }, any, { start_date?: Date | undefined; }>'.
  Types of parameters 'options' and 'options' are incompatible.
    Type 'ResolverOptions<{ start_date?: Date | undefined; }>' is not assignable to type 'ResolverOptions<{ start_date?: unknown; }>'.
      Type '{ start_date?: unknown; }' is not assignable to type '{ start_date?: Date | undefined; }'.typescript(2322)
(property) resolver?: Resolver<{
    start_date?: Date | undefined;
}, any, TFieldValues> | undefined

sample code

import { useForm } from "react-hook-form";
import { z } from "zod";
import { zodResolver } from "@hookform/resolvers/zod";

const schema = z.object({
  start_date: z.coerce.date().optional(),
});

type FormData = z.infer<typeof schema>;

export default function App() {
  useForm<FormData>({
    resolver: zodResolver(schema),
  });

  return null;
}

Expected behaviour

zodResolver should not break Resolver typing when using z.coerce.

z.date()

[bloodykheeng]

@VigilioYonatan That will throw error cos the date comes as a string from backend

[VigilioYonatan]

yes any solution?
Type 'Date | undefined' is not assignable to type 'string | undefined'.

[bloodykheeng]

Work around is to use union
z.union([z.string(),z.date()])
