I am currently trying to use Keda to start a job after having received an event from Azure Event Hub. When I deploy my scaledjob, I see the message (with kubectl describe):

Warning  KEDAScalerFailed      4m29s (x17 over 9m57s)  scale-handler  unable to get eventhub metadata: no storage connection string given

Here is the scaledjob I’m using, it is from the sample we can find in keda’s website

apiVersion: keda.sh/v1alpha1
kind: ScaledJob
metadata:
  name: pi-az-consumer
  namespace: default
spec:

  triggers:

    metadata:
      connectionFromEnv: "Endpoint=sb://{...}.servicebus.windows.net/;SharedAccessKeyName={...};SharedAccessKey={...};EntityPath={...}"
      storageConnectionFromEnv: "DefaultEndpointsProtocol=https;AccountName={...};AccountKey={...};EndpointSuffix=core.windows.net"
      consumerGroup: $Default
      unprocessedEventThreshold: '64'
      activationUnprocessedEventThreshold: '10'
      blobContainer: '{...}'

From what I’ve found on the internet, the connections are what I should have used. Is the problem with my connections? is it elsewhere?
I was expecting a connection or an authentication error but I do not understand why I am told that I did not give the connection string.

Thank you if you have any idea where the problem can come from, I will be keeping this question updated if I find the answer.
