How do you validate a form in a SvelteKit action and return errors?

import { fail } from "@sveltejs/kit";

export const actions = {
  default: async ({ request }) => {
    const data = await request.formData();
    const email = data.get("email");
    if (!email) return fail(400, { email, missing: true });
    // ...
  },
};

• ✓Correct answer: Return fail(status, data); the page receives it as the form prop
• 2Throw error(400) so the error page is shown
• 3Return { status: 400 }
