Durable function service bus trigger in KEDA

I am trying to use KEDA for durable function using python. The trigger for the function is a service bus trigger. The following is the ScaledObject for the function.

apiVersion: keda.sh/v1alpha1
kind: ScaledObject
metadata:
  name: durable-function
  labels: {}
spec:
  scaleTargetRef:
    name: durable-function
  triggers:
  - type: azure-servicebus
    metadata:
      direction: in
      topicName: topic-name
      subscriptionName: durable-function-trigger
      connectionFromEnv: SERVICEBUS_CONNECTIONSTRING_ENV_NAME

The error that I get is general as shown below

fail: Function.df_starter[3]
      Executed 'Functions.df_starter' (Failed, Id=cd5ba757-9b30-4363-b018-fbe56bb26052, Duration=29ms)

I can run the durable function locally using VS Code and works perfectly. Though when I deploy it to local Kubernetes cluster using KEDA, I get a failure.

Bear in mind that I also managed to run a normal function app in KEDA and worked perfectly. I am assuming that the problem is to do with durable function framework/package is not recognised by KEDA.

Can you please advice on this issue?
