Bug report

• [yes ] I have checked other issues to make sure this is not a duplicate.

I tried integrating graphql-apollo with graphql shield, However, I get a validation error as below:

ValidationError: It seems like you have applied rules to Query types but Shield cannot find them in your schema.
    at generateMiddlewareFromSchemaAndRuleTree
 (/node_modules/graphql-shield/src/generator.ts:250:13)

My code:

export default shield(
  {
    Query: {
      viewer: isAuthenticated,
    },
  }
);

#Graphql schema definition:
const RootQuery = new GraphQLObjectType({
  name: "RootQuery",
  fields: {
    viewer: VIEWER,
  },
});


export const schema = new GraphQLSchema({
  query: RootQuery,
  mutation: Mutation,
});

#Integration of graphql shield:

const apolloServer = new ApolloServer({
    schema: applyMiddleware(schema, permissions),
    context: async ({ req }) => {
     
      const user = await getUserContextIsAuthenticated(req);

      return { user };
    },
  });

Viewer's query:

export const VIEWER = {
  type: UserType,
  args: {},
  resolve: async (_parent: any, args: any, { user }: any) => {
    const manager = getConnection("main_db");

    console.log("viwer context", user);
    const id = args.id;
    return await manager.getRepository(Users).findOne({ id: user.id });
  },
};

hello Baloc22m.

If you use GraphQLObjectType to define your schema and you want to apply some rules, you should to use the property name (defined in GraphQLObjectType ) on permissions.

const permisions = shield(
  {
    RootQuery: {
      viewer: isAuthenticated,
    },
  }
);

const RootQuery = new GraphQLObjectType({
  name: "RootQuery", // this identify on shield
  fields: {
    viewer: VIEWER,
  },
});

let me know if its working. 😉
