Hi!

I am trying to get custom validation messages working using ajv-errors.  
A custom message for a format error is working but I cannot get a custom error message for ‘required’ working.

example:

`"zipcode": { "type": "string", "format": "postcode", "errorMessage": {"required": "Postcode is required", "format": "Postcode is in the wrong format"}},`

So In case of a format-error I get the customized message  
But in case of a required error I get the default error message…

What am I doing wrong?

Hi @cornelos,

the `required` is technically an error on the parent of the property not on the property itself. So I would try to customize the error there.

Note that we also now have quite some nice translation support in JSON Forms (via the prop `i18n`) which also allows you to customize the error messages. However this is not yet documented. If you want to try it, you can find some information [here](https://github.com/eclipsesource/jsonforms/issues/1840#issuecomment-984800720).

Doesn’t helps me much. How do I use this l18n feature with The Vue vanilla renderer?  
Where I have to put the keys in (ui)schema?

best regards,

Hi @svnt, the documentation is not yet finished but a much more comprehensive state is available [here](https://deploy-preview-222--jsonforms.netlify.app/docs/i18n). If something is missing or confusing please leave a comment in the [PR](https://github.com/eclipsesource/jsonforms2-website/pull/222).
