Hi @nagarjunaha056

I created a deployment and triggered an alert. After I deleted the deployment without clearing the alert, I saw the error you mentioned. However, in my environment running Edge Orchestrator version 2026.0.0, the alert is automatically cleared after about two minutes. In your environment, does the alert remain active, or does it clear on its own after some time?
