Property 'start' does not exist on type 'ApolloServer'

Question

I'm probably missing an obvious setting or something, but for some reason VS Code doesn't see ApolloServer.start, and I get an inline error:

Property 'start' does not exist on type 'ApolloServer'.

Can anyone see what I'm missing? It works by calling the usual listen method on the server, but I'm trying to add middleware, and this is the documented flow at apollo's official docs.

tsconfig

{
    "compilerOptions": {
        "baseUrl": ".",
        "target": "es5",
        "module": "commonjs",
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "types": ["node"],
        "esModuleInterop": true,
    },
    "include": [
        "apollo-server/*"
    ],
    "exclude": ["node_modules"]
}

index.ts

#!/usr/bin/env node

import express from 'express'
import { ApolloServer, gql } from 'apollo-server-express'
import { readFileSync } from 'fs'
import { resolvers } from './resolvers'

const typeDefs = gql`readFileSync('./schema.graphql').toString('utf-8')`

async function startServer() {
    const server = new ApolloServer({
        typeDefs,
        resolvers,
    })
    
    await server.start() // <---- VSCode complains here
    const app = express()
    server.applyMiddleware({ app })
}

FWIW, I found it right after I posted the question. This is a deprecated pattern. See here
