Example log

{"level":"debug","ts":1598799261.2208235,"logger":"kafka_scaler","msg":"Group autoscaling has a lag of 147410 for topic messages and partition 0\n"}
{"level":"debug","ts":1598799261.2208657,"logger":"scalehandler","msg":"Scaler for scaledObject is active","ScaledObject.Namespace":"default","ScaledObject.Name":"queue-outoscaling-scaler","ScaledObject.ScaleType":"deployment","Scaler":{}}

This seems to be an issue with the HPA config (i.e. too old resource version)

There is a similar HPA issue being reported here

Looks like this has been fixed in upcoming Keda v2 release. More on that here
