General

I am trying to write a resolver and schema in apollo server. However while compiling it giving thie error

Query.Product defined in resolvers, but not in schema

i have this resolver file wherein the resolver and schema is defined as below.

  1. server.mjs
import { ApolloServer } from '@apollo/server';
import { startStandaloneServer } from '@apollo/server/standalone';

// The GraphQL schema
const typeDefs = #graphql type Product { id: String name: String inventory: [Inventory] } type Inventory { qty: Int } type Query { products: [Product] } ;

// A map of functions which return data for the schema.

const resolvers = {
Query: {
products: async () => {
return fetch(http://192.168.99.2:3000/products, {
method: "POST",
mode: "cors",
credentials: "include",
headers: {
"Content-Type": "application/json"
},
}).then(response => response.json())
.then((data) => console.log(data)) // Do something with the data
.catch((error) => console.error(error)) // Handle errors
},
Product: {
inventory: async (parent) => {
const { id } = parent
return fetch(http://192.168.99.2:3000/products/${id}/inventory, {
method: "POST",
mode: "cors",
credentials: "include",
headers: {
"Content-Type": "application/json"
},
}).then(response => response.json())
.then((data) => console.log(data)) // Do something with the data
.catch((error) => console.error(error)) // Handle errors
},
},
}
};

const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [myPlugin],
});

const { url } = await startStandaloneServer(server);
console.log(🚀 Server ready at ${url});

import { ApolloServer } from ‘@apollo/server’;
import { startStandaloneServer } from ‘@apollo/server/standalone’;

// The GraphQL schema
const typeDefs = #graphql type Product { id: String name: String inventory: [Inventory] } type Inventory { qty: Int } type Query { products: [Product] } ;

const resolvers = {
Query: {
products: async () => {
return fetch(http://192.168.99.2:3000/products, {

.then((data) => console.log(data)) // Do something with the data

},
}
};

const server = new ApolloServer({
typeDefs,
resolvers,
plugins: [myPlugin],
});

const { url } = await startStandaloneServer(server);
console.log(🚀 Server ready at ${url});This is the error it gives

You defined Product inside the Query Object in your resolver, you need move to outside
From:

const resolvers = {
  Query: {
    products: () => {/*code*/},
    Product: {
      inventory: () => {/*code*/}
    }
  }
}

To:

const resolvers = {
  Query: {
    products: () => {/*code*/},
  },
  Product: {
    inventory: () => {/*code*/}
  }
}
