"Invalid protocol" when trying to connect to Elasticache Redis in Node.js

I'm trying to connect an ElastiCache Redis to an Express server deployed on ECS. I'm using the Official Redis package for Node.js

I get the Primary Endpoint from ElastiCache as blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379

In my server I try to connect like this

const { createClient } = require("redis");
const pubClient = createClient({ url: 'blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379' });

But when I check the ECS logs I see

/usr/src/app/node_modules/@redis/client/dist/lib/client/index.js:124
throw new TypeError('Invalid protocol');
^
TypeError: Invalid protocol
at Function.parseURL (/usr/src/app/node_modules/@redis/client/dist/lib/c...

Haven't used Redis so no idea why this is happening. Any idea how to use the endpoint properly

even tried with

const pubClient = createClient({ host: 'blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com', port:6379 });

but that also didn't work

The issue was I had to add the prefix redis:// before my Primary endpoint so that it becomes redis://blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379
Github Issue

const pubClient = createClient({ url: 'redis://blablabla.mccjet.ng.0001.euc1.cache.amazonaws.com:6379' });
