When using zod resolver, z.object() does not work with anything other than z.string and refine().

[apn-atobe]

I have created a sample.

If you insert the following z.object() into the resolver, you will see that the console.log in refine() stops working.
We know that z.boolean(), etc. works the same way as z.number().

Is there some kind of rule for using resolver?

const reqBodyScheme = z
  .object({
    password: z.string().min(1, { message: "required" }),
    passwordConfirm: z.string().min(1, { message: "required" })),
    NumberInput: z.number() // <- If you comment this out and use only z.string(), the refine works
  })
  .refine(
    (data) => {
      // Not working
      console.log(data);
      return data.password === data.passwordConfirm;
    },
    {
      message: "Passwords don't match",
      path: ["passwordConfirm"], }
    }
  );

Maybe I'm using it wrong...?

This behavior is not RHF induced, but rather the way Zod works. Check out Zod issue thread: colinhacks/zod#479

the .refine() function defined on the object type doesn't get triggered until the all fields in the object are defined

So this is a spec... I learned a lot.
Thanks for the reply!

@pcp-atobe : Your zod schema defines "NumberInput" as a mandatory field therefore when parsing and validating data by zod library, the target data is not valid and stops at validation phase instead of continuing to "refinement" phase.

Switching "NumberInput" to optional will solve the issue. Working demo: https://codesandbox.io/s/nostalgic-sara-i01e94?file=/src/App.js:364-372

Thank you for editing the sandbox to give a clear example.
It was helpful!

Use partial : object().partial().refine()

If use partial method, all required fields are change to optional.

I fixed to a new group for password.

const reqBodyScheme = z
  .object({
    passwordGroup: z.object({
      password: z.string().min(1, { message: "required" }),
      passwordConfirm: z.string().min(1, { message: "required" })),
    })
    .refine(
      (data) => {
        console.log(data);
        return data.password === data.passwordConfirm;
      },
      {
        message: "Passwords don't match",
        path: ["passwordConfirm"], }
      }
    ),
    NumberInput: z.number() // <- If you comment this out and use only z.string(), the refine works
  });
;

best answer, I tried many things which was mainly offered from another github issues but none of them worked. Thank you so much
