Field "image" must not have a selection since type "String" has no subfields.

I'm getting this error (not on windows) and couldn't fix it with many attempts. I looked at the other issues, but could not find a working solution...

Are things in the right order?

My gatsby-config.js

const path = require("path");

module.exports = {
  siteMetadata: {
    title: "Crisp Studio Blog",
    description: "Our Blog",
    siteUrl: "https://blog.crisp.studio"
  },
  mapping: {
    "MarkdownRemark.frontmatter.author": "AuthorYaml"
  },
  plugins: [
    {
      // keep as first gatsby-source-filesystem plugin for gatsby image support
      resolve: "gatsby-source-filesystem",
      options: {
        path: `${__dirname}/static/assets`,
        name: "assets"
      }
    },
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        path: `${__dirname}/src/content`
      }
    },
    {
      resolve: "gatsby-source-filesystem",
      options: {
        name: "content",
        path: `${__dirname}/src/content/posts`
      }
    },
    "gatsby-transformer-sharp",
    "gatsby-plugin-sharp",
    {
      resolve: "gatsby-transformer-remark",
      options: {
        plugins: [
          {
            resolve: `gatsby-remark-relative-images`
          },
          {
            resolve: "gatsby-remark-images",
            options: {

            }
          },
          {
            resolve: "gatsby-remark-responsive-iframe",
            options: {
              wrapperStyle: "margin-bottom: 1rem"
            }
          },
          "gatsby-remark-prismjs",

      }

    {

      }
    },
    "gatsby-plugin-emotion",
    "gatsby-plugin-typescript",
    "gatsby-plugin-react-helmet",
    "gatsby-transformer-yaml",

      options: {
        postCssPlugins: [
          require("postcss-color-function"),
          require("cssnano")()
        ]
      }
    },
    {
      resolve: `gatsby-plugin-google-analytics`,
      options: {
        trackingId: "UA-XXXX-Y",
        // Puts tracking script in the head instead of the body

        // Disable analytics for users with `Do Not Track` enabled
        respectDNT: true,
        // Avoids sending pageview hits from custom paths
        exclude: ["/preview/**"],
        // Specifies what percentage of users should be tracked
        sampleRate: 100,
        // Determines how often site speed tracking beacons will be sent
        siteSpeedSampleRate: 10
      }
    }
  ]
}

The query in gatsby-node.js

 {
      allMarkdownRemark(
        limit: 2000
        sort: { fields: [frontmatter___date], order: ASC }
        filter: { frontmatter: { draft: { ne: true } } }
      ) {
        edges {
          node {
            excerpt
            timeToRead
            frontmatter {
              title
              tags
              date
              draft
              image {
                childImageSharp {
                  fluid(maxWidth: 3720) {
                    aspectRatio
                    base64
                    sizes
                    src
                    srcSet
                  }
                }
              }

We fixed it. The problem was not using an absolute path in the Yaml we where using.
