Source Code

// src/server.ts
import Koa from "koa";

import server from "./graphql";

const app = new Koa();

server.applyMiddleware({ app });

src/graphql/index.ts

import { ApolloServer, gql } from "apollo-server-koa";

const typeDefs = gql`
  # Comments in GraphQL strings (such as this one) start with the hash (#) symbol.

  # This "Book" type defines the queryable fields for every book in our data source.
  type Book {
    title: String
    author: String
  }

  # The "Query" type is special: it lists all of the available queries that
  # clients can execute, along with the return type for each. In this
  # case, the "books" query returns an array of zero or more Books (defined above).
  type Query {
    books: [Book]
  }
`;

const books = [
  {
    title: "Harry Potter and the Chamber of Secrets",
    author: "J.K. Rowling"
  },
  {
    title: "Jurassic Park",
    author: "Michael Crichton"
  }
];

// Resolvers define the technique for fetching the types defined in the
// schema. This resolver retrieves books from the "books" array above.
const resolvers = {
  Query: {
    books: () => books
  }
};

// The ApolloServer constructor requires two parameters: your schema
// definition and your set of resolvers.
export default new ApolloServer({ typeDefs, resolvers });

Switching to module-alias solves the problem. But I wanna keep tsconfig-paths.

This seems to be an ApolloServer error rather than a graphql-tools error. Closing for now, please reopen if you have more info. Possibly fixed by work along the lines of #1320 ?
