GraphQL Error Field "image" of type "File" must have a selection of subfields. Did you mean "image { ... }"?

Question

I am building a site with gatsby and Netlify CMS. I used the Gatsby Site Starter.

I keep getting a "GraphQL Error Field "image" of type "File" must have a selection of subfields. Did you mean "image { ... }"?" error when trying to deploy to Netlify. Everything works perfectly on localhost, but something seems to be failing with the images. I've looked at the examples provided on the Netlify CMS page and found someone with the exact same setup, a list widget (acting as a gallery) with an image and description inside, here.

config.yml

backend:
  name: git-gateway
  repo: grantballmer/gatsby-starter-netlify-cms
  branch: master

media_folder: static/img
public_folder: /img

collections:

  - name: "gallery"
    label: "Gallery"
    folder: "src/pages/services"
    create: true
    fields: 
      - { label: "Template Key", name: "templateKey", widget: "hidden", default: "gallery" }
      - {label: "Title", name: "title", widget: "string"}
      - label: "Grid"
        name: "grid"
        widget: "list"
        fields: 
          - {label: "Image", name: "image", widget: "image"}
          - {label: "Band Name", name: "band", widget: "string"}`

gallery.js (template file)

import React from 'react';
import { graphql } from 'gatsby';
import Layout from "../components/Layout";
import PhotoGrid from "../components/services/PhotoGrid";

const GalleryTemplate = ({ data }) => {
  const { markdownRemark: gallery } = data;
  const images = gallery.frontmatter.grid;

  return (
    <Layout>
      <PhotoGrid images={images} />
    </Layout>
  );
};

export default GalleryTemplate;

export const galleryQuery = graphql `
  query Gallery($id: String!) {
    markdownRemark(id: { eq: $id }) {
      html
      frontmatter {
        title
        grid {
          image 
          band
        }
      }
    }
  }
`;

/services/photography.md

---
templateKey: 'gallery'
title: photography
grid:
  - band: chris-cordle
    image: /img/chris-cordle-lg.jpg
  - band: 'chirp '
    image: /img/chirp-lg-1-.jpg

I haven't worked with Netlify CMS, but it looks like your Image might be a collection with subfields (example: image { source, id .. }, in which case you should rewrite your query similar to this:

export const galleryQuery = graphql `
  query Gallery($id: String!) {
    markdownRemark(id: { eq: $id }) {
      html
      frontmatter {
        title
        grid {
          image { 
             id
             source
             ..
          }
          band
        }
      }
    }
  }
`;
