Setting server errors

[tjaska]

Is there a way to set errors manually, specifically for when we get them after submitting form?

Usecase:

1. form validation passes
2. mutation runs, server responds with Conflict, e.g. username is already in use
3. show the error under username field

If not currently possible, would it be possible to implement (how complicated?).
What I have in mind is something like this

type ServerError = { field: string; errorMessage: string };

const serverErrors: ServerError[] = [
  {
    field: "username",
    errorMessage: "This username is already in use. Please choose another",
  },
];

<ZodForm 
// if undefined or empty, ignore
serverErrors={serverErrors}
...
/>
