GraphQL验证错误

Question

I am trying out relay-treasure hunt tutorial but getting the following error when I run npm start . I did update my schema by running npm run update-schema .

Uncaught Error: GraphQL validation error ``Cannot query field "game" on type "Query".`` in file `/home/tharaka/My Projects/relay-treasurehunt/js/routes/AppHomeRoute.js`. Try updating your GraphQL schema if an argument/field/type was recently added.

Here's what's inside my AppHomeRoute.js

import Relay from 'react-relay';

export default class extends Relay.Route {
    static path = '/';  
    static queries = {
        game: () => Relay.QL`query { game }`,
    };
    static routeName = 'AppHomeRoute';
}

Answer 1

It seems you have to query everything through either node or viewer , because those are the only fields on the root query type. So maybe try this:

query {
  viewer {
    game
  }
}

Answer 2

In your data/schema.js file...

 var queryType = new GraphQLObjectType({ name: 'Query', fields: () => ({ node: nodeField, // Add your own root fields here viewer: { type: gameType, resolve: () => getGame(), }, }), }); 

Change the viewer property to game . Like this...

 var queryType = new GraphQLObjectType({ name: 'Query', fields: () => ({ node: nodeField, // Add your own root fields here game: { type: gameType, resolve: () => getGame(), }, }), }); 

The name of that property needs to match the field you're querying on in your fragment on your Home route. I suppose as an alternative you could change your route to request viewer instead of game . Do whichever feels better.
