Empty error message gets evaluated as falsy and overriden

[janglad]

Doing this

import z from 'zod';

z.number().min(0, { message: '' }).parse(-1);

Results in an error of

Error: [
{
"code": "too_small",
"minimum": 0,
"type": "number",
"inclusive": true,
"exact": false,
"message": "Number must be greater than or equal to 0",
"path": []
}
]

instead of having an empty message.

Would it be possible to explicitly check if the message is undefined rather than checking if it's falsy? After asking this on the Discord scotttrinh found the line causing this

zod/src/helpers/parseUtil.ts

Line 31 in 3e4f71e

message: issueData.message || errorMessage,

I think I can manage that
