entry/invalid-value

A field’s value has the right type but isn’t allowed: an enum value not in its list, a URL that isn’t absolute, or an item repeated in a unique list. An image that doesn’t exist is image/not-found.

Example

---
title: Pew
kind: esay
---
(with kind = { type = "enum", values = ["essay", "note"] })

Fix

Change the value as the message says. Here kind: essay.
