Not able to subscribe after publishing message either from cmd or from .publish()

I’m trying to implement pub/sub mechanism but I’m getting error whenever I publish message either from command line or through node package.

My client creation code looks like

async setRedisClient(): Promise<void> {
    let redisOpts: RedisClientOptions = this.cloudConfig.getRedisCredentials();
    this.pubClient = createClient(redisOpts);
    await this.pubClient.connect();
    this.subClient = this.pubClient.duplicate();
    await this.subClient.connect();
  }
getPubClient() {
    return this.pubClient;
  }

  getSubClient() {
    return this.subClient;
  }
  

my redis config

return {
      socket: {
        host: "localhost"
        port: 6379,
        tls: false
      },
      legacyMode: true,
      password: "1234"
    }

And my subscription code looks like:

async listenRemoteSockets() {
    logger.info("Subscriber to remote socket updates");
    try {
      // doing this to capture message after 10 seconds.
      setTimeout(async () => {
        await this.redisManager.getPubClient().publish('monitor', 'test from app 22');
      }, 10000);
      await this.redisManager.getSubClient().subscribe('monitor', (err, count) => {
        if (err) {
          logger.error(`>>>>>>>>>>>>> Error occured ${err}`);
        }
        logger.info(`>>>>>>>>>>>>>> Subscribed to ${count}`)
      });

      this.redisManager.getSubClient().on('message', (channel, message) => {
        logger.info(`>>>>>>>>>>>>> Got message from ${channel} => ${message}`)
      })

    } catch (error) {
      logger.error(`Error occured >>>>>>>>>>>>>>> ${error}`)
    }
  }

Following error is thrown once I publish from either command or through .publish()

Looks like PubSub is not working well with legacyMode on, I’ll debug it later today

@omkarrepal yea turn off legacy mode in the subscriber client

edit: or use .v4.subscribe on the legacy client
