Prometheus: queryParameters is an optional parameter

I'm working on upgrading our Keda deployment from 2.11 to 2.14, and one of the changes introduced in 2.13 is the queryParameters field for the prometheus scaler. However, it's documented as a required field yet in the source code the field is marked optional.

My initial impression of reading the trigger specifications
is that missing fields under required fields would result in the request being rejected during an apply but I could be misunderstanding this.

Is there any implications for not setting queryParameters in a prometheus trigger's metadata field?
