I was using redis version 3 in my nodejs app that published a message, to publish this message I was able to fetch specific keys that matched a value. Now I updated to version 4 and it looks like the key fetching part is not working anymore and messages aren’t being published. Here is that piece of code:

async myFunction(someData){
console.log(someData) // this is being logged
this.redisClient.keys('REDIS_SUBSCRIBER_SOCKET_CHANNEL_*', (err, ids) => {
      if(err){
        return console.log(err)  // this is not being logged
      }
      console.log('ids: ' + ids);  // this is not being logged
      ids.forEach(id => {
        console.log(
          'Distributing: ' + JSON.stringify(someData),
        );
        this.publisherClient.publish(id, JSON.stringify(someData));
      });
    });
}

I can only think that the keys aren’t being fetched corrrectly, connection is being done succesfully when my app starts.
