Anything to worry about?
node_redis: Deprecated: The HDEL command contains a "undefined" argument.
This is converted to a "undefined" string now and will return an error from v.3.0 on.
Please handle this in your code to make sure everything works as you intended it to.
DO I NEED TO DO ANYTHING ABOUT THIS?
No, don't worry about it. Open an issue on Github.
Ok thanks will do that
