GraphQL 오류 - 인수 유형이 입력 유형이 될하지만 도착해야합니다

Question

정의되지 않은 내가

export const getPicture = { 
    type: GraphPicture, 
    args: { 
     type: new GraphQLNonNull(GraphQLInt) 
    }, 
    resolve(_, args) { 
     return Picture.findByPrimary(args.id); 
    } 
}; 

export const getPictureList = { 
    type: new GraphQLList(GraphPicture), 
    resolve(_, __, session) { 
     return Picture.findAll({where: {owner: session.userId}}); 
    } 
}; 

및 발생

const query = new GraphQLObjectType({ 
    name: 'Queries', 
    fields:() => { 
     return { 
      getPictureList: getPictureList, 
      getPicture: getPicture 
     } 
    } 
}); 

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

있습니다

Error: Queries.getPicture(type:) argument type must be Input Type but got: undefined. 

getPictureList가 잘 작동을 getPicture이 실패합니다.

getPicture를 GraphQLLIst로 만들려고했으나 도움이되지 않습니다.

args 유형을 입력 유형으로 만들려고했으나 도움이되지 않습니다.

문제는 쿼리하지만 당신은 당신의 인수로 지정한 유형의 반환 형식이 아닙니다.

export const getPicture = { 
    type: GraphPicture, 
    args: { 
     type: new GraphQLNonNull(GraphQLInt) 
    }, 
    resolve(_, args) { 
     return Picture.findByPrimary(args.id); 
    } 
}; 

라는 이름 인수를 의미 가정 "유형"이되어야합니다 :

hero: { 
    type: characterInterface, 
    args: { 
    episode: { 
     description: 'If omitted, returns the hero of the whole saga. If ' + 
        'provided, returns the hero of that particular episode.', 
     type: episodeEnum 
    } 
    }, 
    resolve: (root, { episode }) => getHero(episode), 
},

    },

    } 
};
