What was changed
When a running workflow's task queue has no pollers but is served by a worker deployment with a compute config (serverless workers), the "No workers polling" warning is replaced with an informational alert instead of the alarming "check Kubernetes/ECS, restart workers" guidance.
no-workers-polling-alert.svelte: when the no-workers condition triggers and the workflow has aTemporalWorkerDeploymentsearch attribute, fetch the deployment and check for a compute config. If found, render an info-intent alert explaining the deployment scales to zero when idle and workers start automatically, linking to the deployment page. The warning variant is held hidden until the deployment check resolves so the harsh copy never flashes first.deployment-has-compute-config.ts(+ tests): checks deployment-level compute config plus current/ramping/latest and per-version summaries for non-empty scaling groups, so a pinned older build with a compute config still counts.deployments-service.ts:fetchDeploymentaccepts an optionalonErrorthat suppresses the global error toast — a failed background check just falls back to the existing warning.Why?
Serverless worker deployments scale to zero when idle, so an empty poller list from
DescribeTaskQueueis an expected state, not a sign that workers crashed. The existing warning told users to check their orchestration system and restart workers, which is misleading for deployments Temporal manages.Reported by Brandon: the alert appeared on a running workflow pinned to a serverless deployment (
loan-underwriting-app/build-1) even though the deployment was handling tasks.Checklist
