NewRelic Query value not see in Keda-HPA

[aubernknight]

Hi, I have the following.

I'm running Keda 2.14.2. I am triggering from a New Relic query. I validated the query in NRQL. I have no errors from the Keda pod. However, the HPA is not scaling up. It looks as though the metric "s0-new-relic" is not making it to HPA.
Here is the output from kubectl describe hpa keda-hpa-test-pod-scaler -n test-pod

The kubectl describe hpa keda-hpa-test-pod-scaler -n test-pod give the following:

The New Relic trigger looks like this

triggers:
- type: new-relic
   metadata:
    nrql: "SELECT latest(value) FROM Log
     AND substring(name, indexOf(name, 'taskType-') + 9) = 'test-pod'
     SINCE 2 minute ago"
    threshold: "5"
    activationThreshold: "5"
   authenticationRef:
    name: newrelic-auth
    kind: ClusterTriggerAuthentication

Anyone have any thoughts on this?

When I run the query in New Relic, it works fine. Has anyone seen the behavior?

Seems like the scaler returns 0, you can try to double check here, but the HPA reports 0
