GraphQL schema not complete. Cant query a reference

Hi there,

I am trying to fetch content using graphql but one of the referenced content items doesn’t have the content type in the GraphQL Playground schema.

The query looks like this:

    query {
      catalogueCollection(where:{ slug:"example-slug"}, limit: 1) {
        items {
          productsCollection(limit:50) {
            items {
              slug,
              phonesCollection(limit: 20) {
                items {
                  id,
                  productCode,
                  url,
                  type,
                  someParameters {
                    __typename <---------------
                  },
                }
              }
            }
          }
        }
      }
    }

I can only seem to query __typename under someParameters because it’s the only field that’s recognized by GraphQL Playground app. I checked the schema and its not defined for someParameters content type. For most others I do see definitions in the schema.

Any thoughts on why I’m not able to see the fields for this content type and what a workaround to this is? The field I am trying to query is a single reference to a someParameters content item.
