any idea how i can get rid of this? i don't have any clickhouse queries on my dashboard or alerts.

Hi @Cody Helbling 👋 Could you share the steps you followed to upgrade?
Also, how is SigNoz deployed? Is it on Docker, Swarm, or K8s?

hi @Prashant Shahi! thanks for reaching out! it was our dev environment so i didn't pin the dependency as i wasn't concerned w/ it breaking on updates. running in k8s, deployed using ArgoCD. ArgoCD would automatically update Signoz as the helm chart updated (will pin moving forward 🙂 ). i uninstalled and reinstalled to get it working again. the bummer is we lost some configured alerting, and user accounts from the reset... but it's a dev env so not a huge deal. i don't need help w/ it at this point, but will be more methodical about updates moving forward, and testing update in dev env first.

It is likely caused by older version of otel-collector and/or otel-collector-metrics. Make sure to compare provided values in ArgoCD with the latest one from the chart. https://github.com/SigNoz/charts/blob/main/charts/signoz/values.yaml
@Cody Helbling Thanks for sharing that re-install resolves it.
