validation plugin: Setting errormap on zod

[ewen-lbh]

I'm wondering how I would use z.setErrorMap so that the validation plugin recognizes it (I tried to just do that and it doesn't work).

I know that you can override the thrown error, but I'm looking for something more high-level.

The use-case is to localize Zod error messages in another language, through zod-i18n

I tried the following:

import i18next from 'i18next';
import { z } from 'zod';
import { zodI18nMap } from 'zod-i18n-map';
import  { zodTranslations } from '(somewhere)';

i18next.init({
  lng: 'fr',
  resources: {
    fr: { zod: zodTranslations },
  },
});
z.setErrorMap(zodI18nMap);

...both before and after instanciating the builder, to no avail. I'm guessing that pothos-validation has its own zod object and that it's not global shared state

It looks to me like error maps do get applied correctly for the individual validation messages, but you may need to combine the individual errors manually.

Here's a simple example that just takes the first error and creates a new error using the message from that issue: https://stackblitz.com/edit/typescript-mhtnwd?file=index.ts

Hi! Thanks for the quick response. As it turns out, it was a weird bug with the other library, that I worked around by explicitly passing i18next's t to the lib's error map:

import i18next from 'i18next';
import { z } from 'zod';
import { makeZodI18nMap } from 'zod-i18n-map';
import  { zodTranslations } from '(somewhere)';

i18next.init({
  lng: 'fr',
  resources: {
    fr: { zod: zodTranslations },
  },
});
z.setErrorMap(makeZodI18nMap({ t: i18next.t }));
...
