Wave Runner logs every workflow execution so you can see exactly what ran, what succeeded, and what failed. ## Viewing execution history From the **Workflows** page, click the **History** tab. Wave Runner shows a log of every execution across all your workflows. Filter by: * **Timeframe** — last 24 hours, 7 days, or 30 days * **Status** — All, Completed, Failed, or Running Each row shows the workflow name, execution status, duration, and when it ran. ## Inspecting a single execution Click any execution row to expand it. Wave Runner shows a per-node breakdown of that run: | Field | Description | | --------- | -------------------------------------- | | Node type | The type of action or trigger that ran | | Status | Completed or Failed | | Duration | How long the node took to execute | | Error | Error message if the node failed | Use this to pinpoint exactly which step in a workflow broke and why. ## The Review tab The **Review** tab on the Workflows page surfaces workflows with recent consecutive failures. Check here first when something stops working — Wave Runner flags the affected workflows so you do not have to scan the full execution history. ## Common failure causes * Agent has no phone number assigned (Call Lead node fails) * Phone number credentials disconnected (Send SMS node fails) * HubSpot or GoHighLevel connection expired (CRM nodes fail) * Required variable is empty at runtime (condition or field mismatch) ## Next steps Review trigger configuration to rule out setup issues. Review action node requirements and configuration options.
