ERROR #85901 GRAPHQL

There was an error in your GraphQL query:

Unknown type "ContentfulSizes". Did you mean "ContentfulSecondTry", "ContentfulContentType", or "ContentfulSecondTryEdge"?

File: node_modules\\gatsby-source-contentful\\src\\fragments.js:4:46

Answer 1

Go into your Contentful space, click on Media, and add a dummy image just as a placeholder.

Answer 2

I addition to the answer by Will Sherman , make sure that you publish the image.

On the top right side of the page, you'll see a DRAFT dropdown button. Click on it and select PUBLISH.

Then run gatsby develop again on your local machine
