Expected type MarkdownRemarkFieldsEnum, found frontmatter___date.

Issue when running gatsby build. I removed the blog section from the starter template, both in contents/ and in sidebars.js and in menuItems.js.

ERROR #85901 GRAPHQL

There was an error in your GraphQL query:

Expected type MarkdownRemarkFieldsEnum, found frontmatter___date. Did you mean the enum value frontmatter___title, frontmatter___sidebar, frontmatter___showTitle, or frontmatter___hideAnchor?

File: gatsby/createPages.js:10:10

Ok, I think I figured out what was going on, the headers on my Markdown pages was missing the date field, including other fields.

Here's the complete set of the fields for the pages. It looks like they run optionally in the gatsby develop mode, but they are required in the build mode.

date: 2019-02-13
rootPage: /blah
title: Blah Blah Blah
sidebar: Blah
showTitle: false
hideAnchor: false
