SvelteKit form actions error
form action.*not found|enhance.*error|use:enhance.*failed
Fixes
- 1.Ensure +page.server.ts exports named actions: export const actions = { default: ... }
- 2.Check that form method is POST and action attribute matches the action name
- 3.Import enhance from $app/forms and verify the action returns proper response
