Here is the error message about the index.js cover_image when I use npm run start, and the localhost:8000 page is blank but admin page is ok. I have followed your medium tutorial instructions, could you help me to solve? thanks

` ERROR #85923 GRAPHQL

There was an error in your GraphQL query:

Cannot query field "cover_image" on type "Frontmatter".

If you don't expect "cover_image" to exist on the type "Frontmatter" it is most likely a typo.
However, if you expect "cover_image" to exist there are a couple of solutions to common problems:

• If you added a new data source and/or changed something inside gatsby-node.js/gatsby-config.js, please try a restart of your development server
• The field might be accessible in another subfield, please try your query in GraphiQL and use the GraphiQL explorer to see which fields you can query and what
  shape they have
• You want to optionally use your field "cover_image" and right now it is not used anywhere. Therefore Gatsby can't infer the type and add it to the GraphQL
  schema. A quick fix is to add at least one entry with that field ("dummy content")

It is recommended to explicitly type your GraphQL schema if you want to use optional fields. This way you don't have to add the mentioned "dummy content". Visit
our docs to learn how you can define the schema for "Frontmatter":
