KEDA ScaledObject Failed to ensure HPA is correctly created for ScaledObject Error

[MikeyCSharpDude]

Hi, I am new to K8s, in general. I have installed the TriggerAuthentication object, successfully, but get an error when applying the YAML for the ScaledObject object, whose source is an Azure Queue. The error returned is "Failed to ensure HPA is correctly created for ScaledObject."

Can anyone help as to why I am getting the aforementioned error and how to resolve it? This is blocking me from setting up KEDA for our AKS (Azure Kubernetes Service) Cluster. Thanks!

The HPA is enabled; here's its YAML:

Could you please look into KEDA Operator logs for details?

[MikeyCSharpDude]

Thanks, as this pointed me in the right direction: it's that it can't get the Azure Storage Account connection string: 1.6729592500766408e+09 ERROR scalehandler error resolving auth params {"scalerIndex": 0, "object": {"apiVersion": "keda.sh/v1alpha1", "kind": "ScaledObject", "namespace": "azure-vote", "name": "azure-queue-scaledobject"}, "error": "error parsing azure queue metadata: no connection setting given"}

NOW, I wish it'd actually display this error, as opposed to it saying that the HPA is not correctly created.

[tomkerkhove]

With "display", what do you mean with that?

@zroubalik This may be something for #3764

[zroubalik]

yes, definitely!
