startSubscription从未调用过

我正在尝试使用流星redux中间件。循序渐进地学习了这些教程，但是到目前为止还没有使它正常工作。问题似乎出在startSubscription上：我再也看不到调用的get（）和subscription（）函数，我将控制台调用滑入浏览器和服务器终端中都为空的内部。

// actions.js
import { Meteor } from 'meteor/meteor';
import { startSubscription } from 'meteor-redux-middlewares';
import FaucetRewards from '/imports/api/Rewards/Rewards.js';

export const HOME_REWARDS_SUBSCRIPTION_READY = 'HOME_REWARDS_SUBSCRIPTION_READY';
export const HOME_REWARDS_SUBSCRIPTION_CHANGED = 'HOME_REWARDS_SUBSCRIPTION_CHANGED';
export const HOME_REWARDS_SUB = 'rewards';

export const loadRewards = () =>{

  console.log("actions.loadRewards()"); // I can see this

  let sub = Meteor.subscribe(HOME_REWARDS_SUB); // I can see this in server console and in the sub variable below

  console.log(sub);

  console.log(FaucetRewards.find().fetch()); // Sub is not performed in time, so this is empty as expected

  return(
    startSubscription({
      key: HOME_REWARDS_SUB,
      get: () => { 
        console.log("loadRewards.startSubscription.get()"); // I can never see this
        return (FaucetRewards.find().fetch())
      },
      subscribe: () => {  
        console.log("loadRewards.startSubscription.subcribe()"); // I can never see this
        let subscription = Meteor.subscribe(HOME_REWARDS_SUB); 
        return subscription;
      }
    })
  );

};

我可能忽略了一些愚蠢的事情。有人能帮助我吗？
