Can't generate query files

Inizia da client/src/pages/launches.tsx e package.json, quindi esegui npm run codegen per riprodurre l’errore del parser di Apollo client:codegen. Confronta la sintassi del file e le versioni indicate di TypeScript, Apollo e Node con la configurazione prevista dal tutorial. Il lavoro è completato quando i file delle query vengono generati correttamente senza il Unexpected < syntax error.

Hi,
Following the tutorial but stuck at generating query files.
When I run npm run codegen which is translated to apollo client:codegen --target typescript --watch
I get the following error:

Generating query files with 'typescript' target
    → Syntax error in file:///Users/anatoly/Documents/git/fullstack-tutorial/start/client/src/pages/launches.tsx: Syntax Error: Unexpected <
…

My launches.tsx looks correct:

import React, { Fragment }  from 'react';
import { RouteComponentProps } from '@reach/router';
import gql from 'graphql-tag';

interface LaunchesProps extends RouteComponentProps {}

const Launches: React.FC<LaunchesProps> = () => {
  return <div />;
}

export const LAUNCH_TILE_DATA = gql`
`;

export default Launches;

Tried with node v14.4.0 and v13.12.0, same error. Any suggestions what am I doing wrong? Thank you.
