The API doesn't work (almost): most of the returned property values are null

[nad182]

There must be something wrong with schemas or the way the individual records are fetched.

1. Go to https://swapi-graphql.netlify.app/
2. Try any query, requesting different fields.
   Example:

query MyQuery {
  allPlanets {
    edges {
      cursor
      node {
        climates
        created
        diameter
        edited
        name
      }
    }
  }
}

3. Observe that most of the fields return as null
