GraphQLError: Syntax Error: Expected :, found { Probably a syntax error

Question

我收到这个错误：GraphQLError [Object]: Syntax Error: Expected ":", found "}"，而我正在尝试使用 Apollo 构建 GraphQL 服务器并最终托管在 MongoDB.

但我不明白为什么，有人可以发现我的代码中的错误吗？


const gameWeek = gql`
    type Query {
        GameWeeks: [GameWeek]!
    }
    type Mutation {
        createGameWeek(player_id: ID!): GameWeekUpdateResponse!
        updateGameWeek(player_id: ID!): GameWeekUpdateResponse!
        deleteGameWeek(player_id: ID!)
    }
    type createGameWeek {
        player_id: ID!
        player_name: String!
        points: Float
        rank: Int!
        previous_rank: Int!
        total: Float
        team_name: String!
        team_id: Int
    }
    type GameWeekUpdateResponse {
        success: Boolean!
        message: String
        gameweeks: [GameWeek]
    }
    type GameWeek {
        player_id: ID!
        player_name: String!
        points: Float
        rank: Int!
        previous_rank: Int!
        total: Float
        team_name: String!
        team_id: Int
    }
`;

module.exports = gameWeek;```

Answer 1

在第 8 行你有：

deleteGameWeek(player_id: ID!)

该错误说明您必须通过“:”和“布尔”等数据类型return编写您的突变，编译器在突变声明后发现了一个“}” .您不能让查询、变更或订阅没有 return 值（可能带有标量，但那是另一段历史）。

正确的声明可以是：

deleteGameWeek(player_id: ID!) : GameWeekUpdateResponse!
