Gatsby develop and Gatsby info both returning errors

I don't quite know what happened to my build, Currently gatsby develop is returning TypeError: Cannot read property 'allMarkdownRemark' of undefined pointing to this file

gatsby-node.js:19 graphql.then.results
C:/Users/Anders/sites/gatsby-netlify-cms/gatsby-node.js:19:20

and gatsby info is returning after it returns info about the project error The system cannot find the path specified.

Here is the gatsby-node.js file

const path = require('path')

exports.createPages = ({ graphql, actions }) => {
  const { createPage } = actions
  return new Promise((resolve, reject) => {
    graphql(`
      {
        allMarkdownRemark {
          edges {
            node {
              frontmatter {
                slug
              }
            }
          }
        }
      }
    `).then(results => {
      results.data.allMarkdownRemark.edges.forEach(({ node }) => {
        createPage({
          path: `/posts${node.frontmatter.slug}`,
          component: path.resolve('./src/components/postLayout.js'),
          context: {
            slug: node.frontmatter.slug,
          },
        })
      })
      resolve()
    })
  })
}

I don't quite understand what is going on, I rolled back to changes that were working fine a minute ago, and now getting this weird error. I have tried upgrading node, I have tried reinstalling the gatsby cli. I am stuck. Thanks in advance.

Also including my package.json in case there is incompatibilities
