Output Preview
Each completed execution shows a collapsed preview of the final node's output — key facts at a glance without needing to open the Observer Panel. For quick reference, this is often enough to confirm what the workflow produced.
Where Output Preview Appears
Clicking an execution row expands it inline to show the output preview panel beneath the row header. The preview shows the terminal node's output data — whatever the last node in the workflow produced. For failed executions, it shows the last node that successfully produced output before the error.
Collapsed vs. Expanded View
Output preview is shown in collapsed JSON — only the top-level keys are visible by default. Clicking a key expands it to show its nested value. This prevents long workflows with large output objects from overwhelming the screen.
// Collapsed view (shown by default)
{
"approved": true, ◀ primitive — shown inline
"approvedBy": "usr-001",
"approvedAt": "2026-05-25T11:30:00Z",
"amount": 12450,
"details": { ... }, ◀ object — click to expand
"attachments": [ ... ] ◀ array — click to expand
}
// Expanded details
{
"approved": true,
"approvedBy": "usr-001",
"approvedAt": "2026-05-25T11:30:00Z",
"amount": 12450,
"details": {
"department": "Marketing",
"quarter": "Q1",
"submittedBy": "Sarah Chen",
"lineItems": 14
},
"attachments": [
{ "name": "Q1-Expense-Report.pdf", "url": "..." }
]
}Output Preview in API Response
The history list API returns a outputPreview field on each execution — a truncated version of the terminal node's output, with large arrays summarized and deeply nested objects collapsed to a depth of 2:
// outputPreview in GET /api/workdesk/executions response
"outputPreview": {
"approved": true,
"approvedBy": "usr-001",
"approvedAt": "2026-05-25T11:30:00Z",
"amount": 12450,
"_truncated": true, // indicates full output is available in Observer Panel
"_nodeId": "approve-node-001",
"_nodeName": "Manager Approval"
}Output Preview for Different Workflow Types
| Workflow Type | Typical Output Preview Content |
|---|---|
| Approval Workflow | Decision (approved/rejected), decider identity, timestamp, comment |
| Data Collection Form | Key field values submitted in the final form step |
| Data Sync / ETL | Record count processed, success/failure count, duration |
| Notification Workflow | Recipients count, channels used, delivery status |
| AI Agent Workflow | Agent conclusion, confidence score, actions taken |
Key Output Fields Configuration
Workflow designers can configure which fields are highlighted in the output preview using the Output Summary setting in Flow Studio's workflow properties. Up to 5 key fields can be pinned to always appear in the collapsed preview — even if they are nested deep in the output object.
The output preview is intentionally limited to avoid information overload. For full, browsable output data across all nodes — including intermediate node outputs and error details — open the Observer Panel by clicking "View Full Execution".
