Unable to use partial() with SchemaWithPipe

[rmuchall]

I'm attempting to use v.partial() with a schema that uses a pipe. However, I'm receiving the following error: "TS2345: Argument of type SchemaWithPipe is not assignable to parameter of type Schema$4" EDIT: I am using valibot v0.36 If I ignore this type error and execute the code then partial does not seem to work. Validation errors (issues) are generated for each of the properties in the schema: e.g. "User name is required", "Password is required" etc

import * as v from "valibot";
import {expect, test} from "vitest";

test("email validation", () => {
  const TestSchema = v.pipe(
    v.object({
      userName: v.pipe(
        v.string("User name is required"),
        v.minLength(2, "User name must be at least 2 characters"),
        v.regex(
          /^[a-z0-9]+$/i,
          "User name must only contain alphanumeric characters",
        ),
      ),
      password: v.pipe(
        v.string("Password is required"),
        v.minLength(8, "Password must be at least 8 characters"),
      ),
      confirmPassword: v.pipe(
        v.string("Confirm password is required"),
        v.minLength(8, "Confirm password must be at least 8 characters"),
      ),
      email: v.pipe(
        v.string("Email is required"),
        v.email("Email must be a valid email address"),
      ),
    }),
    v.forward(
      v.check(
        (input) => input.password === input.confirmPassword,
        "Both passwords must be the same"), ["confirmPassword"],
    ),
  );

  // Error occurs on this line:
  const safeParseResult = v.safeParse(v.partial(TestSchema), {email: "xxx"});

  expect(safeParseResult.success).toBe(false);
});

Combining partial with pipe can lead to runtime errors because the types, for example of your check action, are different. Therefore, we do not allow you to use partial with a schema that has a pipeline. The workaround is to pass the schema without a pipeline and add the pipeline afterwards.

import * as v from 'valibot';

type PasswordInput = {
  password?: string;
  confirmPassword?: string;
};

function checkPassword<TInput extends PasswordInput>() {
  return v.forward<TInput, v.PartialCheckIssue<TInput>>(
    v.partialCheck(
      [['password'], ['confirmPassword']] as v.PathKeys<TInput>[],
      (input) => input.password === input.confirmPassword,
      'Both passwords must be the same'
    ),
    ['confirmPassword'] as v.PathKeys<TInput>
  );
}

const BaseSchema = v.object({
  userName: v.pipe(
    v.string('User name is required'),
    v.minLength(2, 'User name must be at least 2 characters'),
    v.regex(
      /^[a-z0-9]+$/iu,
      'User name must only contain alphanumeric characters'
    )
  ),
  password: v.pipe(
    v.string('Password is required'),
    v.minLength(8, 'Password must be at least 8 characters')
  ),
  confirmPassword: v.pipe(
    v.string('Confirm password is required'),
    v.minLength(8, 'Confirm password must be at least 8 characters')
  ),
  email: v.pipe(
    v.string('Email is required'),
    v.email('Email must be a valid email address')
  ),
});

const BaseSchemaWithPipe = v.pipe(BaseSchema, checkPassword());

const PartialBaseSchemaWithPipe = v.pipe(
  v.partial(BaseSchema),
  checkPassword()
);

Many thanks for your fast response and a great library :)
