No Notifications Despite Drift

Thanks for reporting this. To clarify the expected behaviour: when drift detection runs and detects drift, the drifted resources are flagged in the stack's Resources view, and the run itself appears under Account → Runs filtered to drift detection.

A Slack notification can then be triggered through a notification policy that matches drift-detection runs — for example by checking run.drift_detection == true and routing the event to Slack.

Notification policies are configured at the space level, so they apply to accessible stacks unless narrowed by stack name/labels — the policy needs to live in a space that covers the stack rather than being attached to it.

If Slack notifications are not firing, please double-check that the policy conditions match drift-detection runs with actual changes, and that the stack runs on a private worker pool — drift detection requires one.

If you're still having trouble, please reach out to support@spacelift.io and we'll be happy to help investigate.
