错误：未知指令"；关系；。有一大堆neo4j

我正在尝试neo4j的grand stack starter，在完成所有graphql模式部分后，API模块出现以下错误。它抱怨指令“关系”和“密码”是未知的。 我重新安装了neo4j graphql js，但没有解决问题。 下面是错误消息

import { ApolloServer, gql, makeExecutableSchema  } from "apollo-server";
import { v1 as neo4j } from "neo4j-driver";
import { augmentSchema } from "neo4j-graphql-js";
import dotenv from "dotenv";

// set environment variables from ../.env
dotenv.config();



const schema = makeExecutableSchema({
  typeDefs,
  resolvers
});

const augmentedSchema = augmentSchema(schema);

const driver = neo4j.driver(
  process.env.NEO4J_URI || "bolt://localhost:7689",
  neo4j.auth.basic(
    process.env.NEO4J_USER || "neo4j",
    process.env.NEO4J_PASSWORD || "letmein"
  )
);


const server = new ApolloServer({
  context: { driver },
  schema: augmentedSchema
});

server.listen(process.env.GRAPHQL_LISTEN_PORT, "0.0.0.0").then(({ url }) => {
  console.log(`GraphQL API ready at ${url}`);
});

任何人都可以帮助解决这个问题！提前感谢

如中所述

注意：仅当使用现有GraphQLSchema对象时才使用augmentSchema。在大多数情况下，您应该使用makeAugmentedSchema，它可以从类型定义构造GraphQLSchema对象

发生错误的原因是您试图使用

makeExecutableSchema

创建架构。

@relation

和

@cypher

指令仅由

neo4j-graphql

使用。由于它们实际上没有定义为模式的一部分，因此使用

makeExecutableSchema

构建模式将导致错误，就像使用任何其他未定义的指令一样

您应该只使用

makeAugmentedSchema

：

const schema = makeAugmentedSchema({
  typeDefs,
  resolvers,
})
const driver = /* ... */
const server = new ApolloServer({
  context: { driver },
  schema,
})

听上去，您使用了错误的函数来构建模式。请编辑您的问题以包含相关代码。谢谢@DanielRearden，我已经用我的代码更新了帖子！。提前谢谢！！非常感谢@Daniel Rearden！将makeExcutableSchema替换为MakeAgmentedSchema后，错误消失！！

const schema = makeAugmentedSchema({
  typeDefs,
  resolvers,
})
const driver = /* ... */
const server = new ApolloServer({
  context: { driver },
  schema,
})
