Problem with onMessage()

[sudiptosarkar]

My App works flawlessly using the ol' [email protected]. But after upgrading to @socket.io/redis-adapter (I tried all versions from 7.0.0), the app gets this problem:

TypeError: object is not iterable (cannot read property Symbol(Symbol.iterator))

For reference, I printed the opts right before the problem line # 131:
