error when adding schema markup

[Sai Krishna]

It looks like adding a schema markup script causes a rollup error

Schema

<script type="application/ld+json">
    {
      "@context": "https://schema.org/",
      "@type": "Recipe",
      "name": "Party Coffee Cake",
      "author": {
        "@type": "Person",
        "name": "Mary Stone"
      },
      "datePublished": "2018-03-10",
      "description": "This coffee cake is awesome and perfect for parties.",
      "prepTime": "PT20M"
    }
    </script>

Error

[!] (plugin rollup-plugin-elder) Error: Cannot find module './transformers/ld+json'

Would appreciate any help. Thank you!
