redis acquires content asynchronously, which is usually provided by the callback parameter. You need to obtain the content in the callback. Or directly use async/await to implement

// async + await 
async function test() {
  await Redis.set('something', '');

  const data = await Redis.get('something');

  // 
  console.log(data);
}
