SuperPlane Monitor

Inspect, debug, and manage workflow executions.

Quick Reference

Verify CLI Is Installed

Before any debugging, confirm the CLI is available:

superplane whoami

If command not found: stop and tell the user to install the CLI from https://docs.superplane.com/installation/cli. Debugging requires the CLI to inspect events, executions, and queues.

Debugging Workflow

1. Find the Canvas

superplane canvases list

2. List Recent Events

superplane events list --canvas-id <canvas_id>

Each event is a trigger firing that starts a run.

3. Trace the Execution Chain

superplane events list-executions --canvas-id <canvas_id> --event-id <event_id>

Look for:

• Failed — the node that errored
• Pending/Running — possibly stuck
• Skipped — bypassed by a branch (If/Filter)

4. Inspect a Node’s History and Payloads

superplane executions list --canvas-id <canvas_id> --node-id <node_id> -o yaml

Check if failures are recurring. For expression errors, inspect the actual payload structure:

• rootEvent.data.data — the trigger’s real event payload (the double .data is the event envelope wrapping the webhook payload)
• input — what the node received from its upstream node (also has { data, timestamp, type } envelope)
• resultMessage — the exact error, including which expression field was nil

Use these real payloads to fix expression paths rather than guessing from documentation.

5. Fix and Re-run

Update the canvas, then trigger a new run from the UI or via a manual_run trigger.

Common Failure Patterns

Auth Failure

Node fails immediately with permission error. Check:

superplane integrations list
superplane secrets list

Verify the integration is connected and the secret is valid.

Expression Error

Node fails referencing a missing field. Check:

• Node name matches exactly (case-sensitive) in $['Node Name']
• Upstream node actually emits the expected field
• Root payload contains the expected data

Stuck Queue

Executions pile up without progressing:

superplane queue list --canvas-id <id> --node-id <nid>

Causes: node is paused, Approval waiting for human input, Time Gate holding, external service unresponsive.

Clear stuck items:

superplane queue delete --canvas-id <id> --node-id <nid> --item-id <iid>

Merge Never Fires

Merge waits for ALL incoming edges. If one branch is stuck, filtered out, or failed, Merge blocks. Check every upstream branch.
