Unable to run Gatsby application using npm run develop command

Question

I am developing my first project with Gatsby and prismic. Today when i tried to start my development server i faced this error. I searched but i couldn't find similar errors anywhere. I am completely blocked on this one and have no clue what's causing this error.

extract from package.json :

"scripts": {
    "build-dev": "env-cmd -f .env gatsby build",
    "develop-dev": "env-cmd -f .env gatsby develop",
      ....
  },

The error

ERROR 

UNHANDLED REJECTION Union type PrismicAllDocumentTypes must define one or more member types.



  Error: Union type PrismicAllDocumentTypes must define one or more member types.

Have you installed npm install -g gatsby-cli.

[Update] Prismic is not longer recommending the gatsby-source-prismic-graphql plugin.

Here's an article that'll help you migrating to the other one:

Error says that PrismicAllDocumentTypes has no children. You need to check that your prismic repo has at least one content type and, most important, you have at least one schema added to your codebase and gatsby-config.js:

module.exports = {
  plugins: [
    {
      resolve: `gatsby-source-prismic`,
      options: {
        repositoryName: `repositoryName`,
        accessToken: `accessToken`,
        linkResolver: ({ node, key, value }) => post => `/${post.uid}`,
        schemas: {
          page: require("./src/schemas/page.json"),
        },
      },
    },
  ],
}

in your gatsby-condig.js:

 resolve: 'gatsby-source-prismic',
      options: {
        repositoryName: 'gatsby-starter-prismic',
        accessToken: `${process.env.API_KEY}`,
        // Get the correct URLs in blog posts
        linkResolver: () => post => `/${post.uid}`,
        // PrismJS highlighting for labels and slices
        htmlSerializer: () => prismicHtmlSerializer,
        // Remove this config option if you only have one language in your Prismic repository
        lang: 'en-gb',
      },
    },

you are probbly using .dotenv - a way to pass secret keys outside of publc ic repo's.

in your root directory create a file named " .env.develop " and a second: ".env.prod "

.env.develop file content: API_KEY = COPYPASE YOUR API KEY HERE
