The result of `getIntrospectionQuery` does not match `IntrospectionQuery` type

[Woodz]

getIntrospectionQuery only requests the name field from the root queryType object
(https://github.com/graphql/graphql-js/blob/6e48d16f92b9a6df8638b1486354c6be2537033b/src/utilities/getIntrospectionQuery.ts)

queryType { name }

yet the IntrospectionQuery datatype defines queryType as IntrospectionNamedTypeRef (https://github.com/graphql/graphql-js/blob/main/src/utilities/getIntrospectionQuery.ts#L167) which requires kind as well

export interface IntrospectionNamedTypeRef<
  T extends IntrospectionType = IntrospectionType,
> {
  readonly kind: T['kind'];
  readonly name: string;
}

This means that copying the result of the querying a GQL API with the introspection query as JSON and trying to assign to IntrospectionQuery will fail with:

The types of '__schema.queryType' are incompatible between these types.
Property 'kind' is missing in type '{ name: string; }' but required in type 'IntrospectionNamedTypeRef'.

Bumping this.

Still seeing this issue. At the moment, chucking in a @ts-ignore but would be nice to have a firmer fix.

Exact same situation, passing an introspection in JSON into buildClientSchema. Using the very latest graphql at 16.4.0.

import * as introspectionResult from "../../../graphql.schema.json";

const schema = buildClientSchema(introspectionResult);

Produces the following error:

Argument of type '{ __schema: { queryType: { name: string; }; mutationType: { name: string; }; subscriptionType: null; types: ({ kind: string; name: string; description: string; fields: null; inputFields: null; interfaces: null; enumValues: null; possibleTypes: null; } | ... 9 more ... | { ...; })[]; directives: ({ ...; } | { ...; })...' is not assignable to parameter of type 'IntrospectionQuery'.
  The types of '__schema.queryType' are incompatible between these types.
    Property 'kind' is missing in type '{ name: string; }' but required in type 'IntrospectionNamedTypeRef<IntrospectionObjectType>'

Other issues downstream in users of this library:

• Schema created by apollo client:download-schema is not type-compatible with buildClientSchema() apollographql/apollo-tooling#1491
• [@types/graphql] kind is not required for queryType DefinitelyTyped/DefinitelyTyped#34649 - this contains an incorrect fix, as it is still broken in the latest version.

Wondered if making kind option would be enough, and it creates further problems upstream.

export interface IntrospectionNamedTypeRef<
  T extends IntrospectionType = IntrospectionType,
> {
  readonly kind?: T['kind'];
  readonly name: string;
}

@IvanGoncharov is it simply a matter of fixing getIntrospectionQuery to include kind as hinted at above?

[yaacovCR]

Or is that silly because the kind is obvious for root types? And we need a new introspection type for root types?
