at RedisCommandsQueue._RedisCommandsQueue_handlePubSubReply (/mnt/c/Projects/konnectcore/app/sse/sse/node_modules/#redis/client/dist/lib/client/commands-queue.js:283:100)
It's working fine while using node redis "redis": "^2.8.0".

I had a similar issue where I was using probably some old way of subscribing and receiving the messages. Something like this:
sub.on('message', (channel, message) => {
redisClient.hSet('values', message, someFunction);
});
sub.subscribe('channel');
I hope you are using the right way of publishing and subscribing to a channel in redis client. Here is one example from their documentation:
// This is how you create the client
import { createClient } from 'redis';
const client = createClient();
// This is the subscriber part
const subscriber = client.duplicate();
await subscriber.connect();
await subscriber.subscribe('channel', (message) => {
console.log(message); // 'message'
});
// This is an example of how to publish a message to the same channel
await publisher.publish('channel', 'message');
