    Hi Zac,

    Unfortunately your video on the Gatsby Basics course Creating Content with Markdown (MDX) is now out of date because gatsby-mdx is depreciated.

    I managed to switch to using gatsby-plugin-mdx and it works fine, also the video is a lot longer than 5:03 🙂

    This error also effects the next video Creating Dynamic Page Templates. There is no longer a code object in mdx, only body and when I try to code along as per the instructions I get an error:

    ERROR #85907 GRAPHQL

    There was an error in your GraphQL query:

    – Unknown field ‘code’ on type ‘Mdx’.

    To fix this you have to do:

    query MyQuery($slug: String!) {
    mdx(frontmatter: { slug: { eq: $slug } }) {
    frontmatter {


    export default ({
    data: {
    mdx: {
    frontmatter: { title },
    body: content,
    }) => (

    Now I get the post body showing 🙂
