HTTPScaledObject is throwing errors when installed and scaling is not happening

[Sathya-omnius]

Hi Team,
we are trying to scale the Java Microservice based on Http load, there are the steps we have followed, we have keda installed and we are scaling other micro services based on Redis & PostgreSQL scalers
1)helm install --create-namespace -n ${NAMESPACE} keda kedacore/keda
2)install --create-namespace -n ${NAMESPACE} http-add-on kedacore/keda-add-ons-http

everything got installed successfully but in coralogix we are getting lot of errors and scaling is not working.
errors from corologix

keds.sh in Kubernetes:

this is our code as we dont have any host for this micro service we have not included hosts variable.
kind: HTTPScaledObject
apiVersion: http.keda.sh/v1alpha1
metadata:
name: document-service-scaledobject
spec:
#host: "myhost.com"
#targetPendingRequests: 10
scaleTargetRef:
deployment: document-service
service: document-service
port: 8080
replicas:
min: 1
max: 5

could some one provide what additional things i need to as part of implementation, appreciate your support.
