REDIS - global.get results in the ERROR

Hello I have changed the default context storage to the REDIS.

Configuration:

contextStorage: {
    redis: {
        module: require("node-red-context-redis"),
        config: {
        	 host: "**,
                 port:***,
        }
    }
},

When fetching the global data using the change node, it works. But with the function node, it shows: "Error: Callback must be a function"

Tried with and without setting the storeName.

Try the async version

"Writing Functions : Node-RED" https://nodered.org/docs/user-guide/writing-functions#asynchronous-context-access

Edit...
Seems this a known issue (and unreleased code)...

The async function works well but unfortunately this doesn't resolve my issue.
