      This error can occur if you are using an out of date version of the Idyll
      components with a newer version of the Idyll build tool. To install the
      latest idyll-component, run \`npm install idyll-components@latest\`.

      If you are reading the components from a local folder (e.g. ./components/default),
      you can refresh components in that folder by copying from ./node_modules/idyll-components/src/
      to your local directory.
