Understanding (and fixing ?) warning message

Oh hang on!

try this.

function RedisConfig(n) {
    RED.nodes.createNode(this, n);
    this.name = n.name;
    this.cluster = n.cluster;
    if (this.optionsType === "") {
      this.options = n.options;
    } else {
      RED.util.evaluateNodeProperty(n.options, n.optionsType,this,undefined,(err,value) => {
           if(!err) {
            this.options = value
          }
      });
    }
  }
  RED.nodes.registerType("redis-config", RedisConfig);

it was treating the callback as an msg - and not a callback
This might not stop the child nodes trying to use the Config too early, but that is a different problem if that still continues.

example:

3 Dec 14:20:37 - [error] [redis-config:Cluster] Missing options in the redis config - Are you upgrading from old version?

So you might need to address that also

Remember to restart Node RED
