Done
(any) — fires when condition is met or max iterations reached
Configuration
| Parameter | Type | Default | Description |
|---|---|---|---|
conditionField |
text | "done" |
The payload key to check each iteration. This is a raw key name (not a template) — it references loop-body state directly. Supports dot notation for nested fields (e.g. data.done), same as the Condition node. |
conditionValue |
text | "true" |
The value to compare against. Supports {{variable}} templates, re-evaluated against the current payload on each iteration — e.g. {{target}} compares the condition field to another payload value that can change inside the loop. |
conditionMode |
dropdown | until |
until stops when condition matches; while continues as long as it matches. |
maxIterations |
number | 20 |
Safety limit to prevent infinite loops. The loop exits via Done when this limit is reached. |
Output Payload
When the loop exits via the Done outlet, the payload includes:
_while_exceeded
Boolean. true if the loop stopped because maxIterations was reached rather than the condition being satisfied.
