Array and date properties modify each other

[ciscoheat]

When you have an object with dates and arrays, if the array fails validation, dates will be "".

V4 - Valid: false, Date:
V3 - Valid: false, Date: Sun Oct 01 2023 03:00:00 GMT+0300 (Eastern European Summer Time)

Failing test:

import { z as z4 } from 'zod/v4';
import { z as z3 } from 'zod/v3';
import { zod4, zod as zod3 } from 'sveltekit-superforms/adapters';
import { superValidate } from 'sveltekit-superforms';

export const load = async () => {
    const data = {
        date: new Date('2023-10-01T00:00:00Z'),
        items: [{ id: 1, product: 'Product A' }, { id: 2, product: 'Product B' }, { id: 'bad' }]
    };

    // -------------------------------
    const schema4 = z4.object({
        date: z4.date(),
        items: z4.array(
            z4.object({
                id: z4.number(),
                product: z4.string()
            })
        )
    });
    const form4 = await superValidate(data, zod4(schema4), {
        errors: false
    });
    console.log(V4    -    Valid: ${form4.valid}, Date: ${form4.data.date});

    // -------------------------------
    const schema3 = z3.object({
        date: z3.date(),
        items: z3.array(
            z3.object({
                id: z3.number(),
                product: z3.string()
            })
        )
    });
    const form3 = await superValidate(data, zod3(schema3), {
        errors: false
    });
    console.log(V3    -    Valid: ${form3.valid}, Date: ${form3.data.date});
};
