SuperPlane Monitor

Inspect, debug, and manage workflow executions.

Quick Reference

Task	Command
List events for canvas	`superplane events list --canvas-id <id>`
Trace an event's executions	`superplane events list-executions --canvas-id <id> --event-id <eid>`
List node executions	`superplane executions list --canvas-id <id> --node-id <nid>`
Cancel execution	`superplane executions cancel --canvas-id <id> --execution-id <eid>`
List queued items	`superplane queue list --canvas-id <id> --node-id <nid>`
Delete queued item	`superplane queue delete --canvas-id <id> --node-id <nid> --item-id <iid>`

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.

If debugging will require canvas edits, detect mode first:

superplane canvases get <canvas_name_or_id> -o json | jq '.metadata.canvasVersioningEnabled'

true: apply fixes with superplane canvases update --draft ..., then create/publish via superplane canvases change-requests ....
false: apply fixes with superplane canvases update ... (no --draft); canvases change-requests is unavailable.
Org override: if organization versioning is enabled, all canvases are effectively versioned.
Org override: if organization versioning is disabled, canvases can still toggle versioning individually.

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.

For branching/channel issues, inspect outputs in execution YAML (not just top-level result):

A node can show RESULT_PASSED while only emitting on a non-default channel (for example, failed)
Confirm emitted channel names under outputs match edge wiring (success, failed, default, etc.)
If downstream behavior looks inconsistent with events list-executions, trust the node's outputs block for routing truth

5. Fix and Re-run

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

For versioning-enabled canvases, use the change-request lifecycle:

superplane canvases update <name-or-id> --draft --file canvas.yaml
superplane canvases change-requests create <name-or-id> --title "Fix failing workflow"
superplane canvases change-requests publish <change-request-id> <name-or-id>

If publish is blocked, inspect with change-requests get and then use approve, unapprove, reject, reopen, or resolve as needed.

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.
