   * * Overriding field types is disallowed, instead use the `createTypes`
   *   action. In case of types added from third-party schemas, where this is not
   *   possible, overriding field types is allowed.
   * * New fields will not be available on `filter` and `sort` input types. Extend
   *   types defined with `createTypes` if you need this.
   * * In field configs, types can be referenced as strings.
   * * When extending a field with an existing field resolver, the original
   *   resolver function is available from `info.originalResolver`.
   * * The `createResolvers` API is called as the last step in schema generation.
   *   Thus, an intermediate schema is made available on the `schema` property.
   *   In resolver functions themselves, it is recommended to access the final
   *   built schema from `info.schema`.
   * * Gatsby's data layer, including all internal query capabilities, is
   *   exposed on [`context.nodeModel`](/docs/node-model/). The node store can be
   *   queried directly with `getAllNodes`, `getNodeById` and `getNodesByIds`,
   *   while more advanced queries can be composed with `runQuery`. Note that
   *   `runQuery` will call field resolvers before querying, so e.g. foreign-key
   *   fields will be expanded to full nodes. The other methods on `nodeModel`
   *   don't do this.
   * * It is possible to add fields to the root `Query` type.
   * * When using the first resolver argument (`source` in the example below,
   *   often also called `parent` or `root`), take care of the fact that field
   *   resolvers can be called more than once in a query, e.g. when the field is
   *   present both in the input filter and in the selection set. This means that
   *   foreign-key fields on `source` can be either resolved or not-resolved.
   *
