Discord js keyv throwing ECONNREFUSED - node.js

Question

I'm trying to use Keyv, following this tutorial: https://discordjs.guide/keyv/#command-handler and I'm using the command handler code as well.
In my index.js, I run something like this: (with the appropriate imports for Keyv of course)
const Keyv = require('keyv');
const mykeyv = new Keyv('redis://user:pass#localhost:6379');
client.on('message', message =>{
...//skipping some command handler stuff
command.execute(message, args, mykeyv)
})
And then when I run this, I initially get the correct and expected client.on('ready') messages, but then a few seconds after the following error pops up:
events.js:292
throw er; // Unhandled 'error' event
^
Error: connect ECONNREFUSED 127.0.0.1:6379

I'm not sure what this error is about, can someone help me?
