有一个npm包，允许您缓存对redis的axios get调用。看完文档后，我似乎无法将其缓存到redis。我正在使用推荐的axios 0.18.1 版本，但仍然没有喜悦。我错过了什么？

// Set-up code
const Axios = require('axios');
const Cache = require('axios-cache-adapter');
const Redis = require('redis');

const redis = Redis.createClient(); // using localhost
const redisStore = new Cache.RedisStore(redis);

const cacheMe = Cache.setupCache({
  maxAge: 30 * 60 * 1000,
  store: redisStore,
  exclude: {
    query: false
  },
  debug: true
});
const axios = Axios.create({
  cache: cacheMe.adapter
});

// Snippet of axios call fromCache is always undefined
      async resolve(root) {
        const url = solrApi.getReports({ id: root.id });
        const resp = await axios.get(url);
        console.log(`Found ${ resp.data.response.numFound } record(s) in ${ resp.data.responseHeader.QTime } ms (fromCache: ${ resp.request.fromCache }`);
        return resp.data.response.docs;
      }
