SQS Scaler

[brunozrk]

Trying to scale pod with SQS scaler, but the HPA is not working, any tip to troubleshoot? Probably it is not a Keda issue, but I dont know where to call on

The event:

unable to get external metric default/AWS-SQS-Queue-keda-queue-1/&LabelSelector{MatchLabels:map[string]string{scaledObjectName: aws-sqs-queue-scaledobject,},MatchExpressions:[]LabelSelectorRequirement{},}: 
unable to fetch metrics from external metrics API: the server is currently unable to handle the request (get AWS-SQS-Queue-keda-queue-1.external.metrics.k8s.io)

# kubectl version
