[Error: Query.Mutation defined in resolvers, but not in schema]

Question

const { ApolloServer, gql } = require('apollo-server-express');
const express = require('express');

const port = process.env.PORT || 4000;
const notes = [
    { id: '1', content: 'This is a note', author: 'Adam Scott' },
    { id: '2', content: 'This is another note', author: 'Harlow Everly' },
    { id: '3', content: 'Oh hey look, another note!', author: 'Riley Harrison' }
   ];

const typeDefs = gql `
    type Note {
        id: ID
        content: String
        author: String
    }

    type Query {
        hello: String
        notes: [Note]
        note(id: ID!): Note
    }

    type Mutation {
        newNote(content: String!): Note
    }
`;
const resolvers = {
    Query:{
        hello: () => 'Hello World',
        notes: () => notes,
        note: (parent, args) => {
            return notes.find(note => note.id == args.id);
        },
    Mutation: {
        newNote: (parent, args) => {
            let noteValue = {
                id : String(notes.length + 1),
                content : args.content,
                author: 'Adam Scott',
            };
            notes.push(noteValue);
            return noteValue;
        }
    }
    },
}

有些人有命名问题，但我似乎在解析器和架构中使用了相同的名称。请告诉我，这是我在 GraphQL 和 Express 中的第二天。我故意删除了 express 对象和中间件的导入和分配，因为它不允许我 post.

我想你只是少了一个大括号。

const resolvers = {
    Query:{
        hello: () => 'Hello World',
        notes: () => notes,
        note: (parent, args) => {
            return notes.find(note => note.id == args.id);
        }
    }, <==== THIS IS MISSING =====>
    Mutation: {
        newNote: (parent, args) => {
            let noteValue = {
                id : String(notes.length + 1),
                content : args.content,
                author: 'Adam Scott',
            };
            notes.push(noteValue);
            return noteValue;
        }
    }
