Iterator Node

Iterator takes a list from payload and emits one execution item per element.

Configuration Fields

Field	Required	Purpose
List Path	Yes	Payload path containing array/list

Setup Steps

1. Add Iterator where list expansion is required.
2. Set list path.
3. Connect downstream processing path for one-item-at-a-time handling.

Best Practices

• Validate list existence before iteration.
• Limit list sizes for predictable runtime cost.
• Save per-item results with correlation IDs.

Common Issues

• Path not found errors from missing list field.
• High execution load when list cardinality is too large.
