Inside the Workflow: Debugging & Execution Data

Master execution history, error traces, data replay, and node-level debugging techniques.

Learning Objectives

  • Inspect execution history and past run logs
  • Use the Retry feature to replay failed executions
  • Set up Stop and Error behavior on sensitive nodes

Inside the Workflow: Debugging & Execution Data

When workflows fail in production, knowing how to inspect raw execution traces separates amateurs from engineering professionals.

The Executions View

Every workflow trigger creates an execution record:

  • Success (Green): Completed all node paths.
  • Error (Red): Halted due to an unhandled exception or API failure.
  • Waiting (Yellow): Paused waiting for a webhook callback or approval.

Click any execution to open the visual debugger. Nodes that executed highlight in green; the failed node highlights in red with the stack trace displayed.

Node Error Settings

Under any node settings tab, configure error behavior:

  • On Error -> Continue Regular Output: The node outputs an error object instead of killing the entire pipeline.
  • On Error -> Stop Workflow: Default behavior; halts execution immediately.
  • Retry On Fail: Automatically re-attempts network requests up to 5 times with exponential backoff.
