future/coerceFormValue (zod v4): .required(...) is improperly handled

[transparent-citizen]

Say you have this schema:

const schema = z.object({
	text: z.string(),
	number: z.number().optional(),
});

✅ This coerced schema parses without an issue:

const result = coerceFormValue(schema).safeParse({
	text: 'text',
	number: '300',
});

console.log(result);
// { success: true, data: { text: "text", number: 300 }

❌ However, using .required(...) to require an optional z.number() or z.bigint() fails:

const stricterSchema = schema.required({
	number: true
});

const result = coerceFormValue(stricterSchema).safeParse({
	text: "text",
	number: "300",
})

console.log(result);
// { success: false, error: { number: ["Invalid input"] }

Interestingly, if you make an optional z.string(), z.boolean(), or z.object() required like above, it works fine.
What seems to be affected is at least z.number() and z.bigint().

This surfaces as "Invalid input: expected number, received string".

hi @transparent-citizen
Thanks for reporting the issue.

I fixed the bug here. If you need the fix right away, you can try it via pkg.pr.new.

Hi @chimame! I tested the pkg.pr.new package, and it worked without any issues. Thank you very much!

This is fixed in v1.13.3.
