Issue with fetchSockets() and getNumSub()

[omkarrepal]

Hi Team,

I'm facing issue with fetchSockets()

When I'm calling function fetchSockets() it's throwing following error.

Cannot read properties of undefined (reading 'then')\n at RedisAdapter.getNumSub

It's going inside following code block inside getNumSub() method

 else if (typeof this.pubClient.pSubscribe === "function") {
            return this.pubClient
                .sendCommand(["pubsub", "numsub", this.requestChannel])
                .then((res) => parseInt(res[1], 10));
        }

and then it throws above error.

Redis version is ^4.3.1
Socket.IO version is ^4.5.2
I'm using latest redis-adapter version ^7.2.0
