[lambertpan]

Report

I have recently updated keda and keda-http-add-on. The versions are below

• keda-2.11.2
• keda-add-ons-http-0.5.2
  I see the following errors in keda-operator
  2023-08-01T07:21:55Z ERROR scale_handler error getting metric spec for the scaler {"scaledObject.Namespace": "keda", "scaledObject.Name": "keda-add-ons-http-interceptor", "scaler": "externalScaler", "error": "got empty metric spec"}
  In the scaled object status I see the following
  status:
  conditions:
  • message: Triggers defined in ScaledObject are not working correctly
    reason: TriggerError
    status: "False"
    type: Ready
  • message: Scaling is not performed because triggers are not active
    reason: ScalerNotActive
    status: "False"
    type: Active
  • status: Unknown
    type: Fallback

Hey @lambertpan, this is a duplicate of #718 and has been fixed by #720. Unfortunately, we still haven't released a new version of the add-on since the patch got merged. You can either build new images from the master branch of this repository and use them, or delete the ScaledObject for the Interceptor and scale the Interceptor manually.

[jacob-jameson]

Is it possible to release an image that contain this fix? My team wants to use this tool for an internal tool (we understand and accept the risks involved in the beta status of this add-on). We would like to not have to change the repo from which we pull the image, so a release containing this fix would be awesome.

[JorTurFer]

We build all the merged commits. You can use canary for using the main branch, or the commit sha for a specific commit (6e7f15d in this case).
I think that we could cut a release this month, WDYT @tomkerkhove @t0rr3sp3dr0 ?

[JorTurFer]

Hello,
The error was in the HTTP add-on code and chart. We have released today a new version (0.6.0) with this and other fixes, please give it a try and let me know if this has solved
