Loop Subflow

The Loop Subflow Node allows you to run a branch of your project in a loop over a list of inputs. To set up the node, make sure you are inputting a list of any form.

This node provides two execution branches:

• Loop This branch runs once for each item in the input list. During each iteration, the current item is available via the current_item variable. Important: If you want to collect results across all iterations, you must attach an output node at the end of the Loop branch. Only outputs explicitly emitted there will be aggregated.

• Done This branch executes after all items have been processed by the Loop branch. If outputs were emitted during the Loop branch, they will be aggregated and made available here.

Common Pitfalls

• List passed as a string If the entire list appears inside current_item instead of a single element, the input may have been parsed as a string rather than a list.

  Example:

  • Incorrect: "[item_1, item_2, item_3]" (string)

  • Correct: [item_1, item_2, item_3] (list)

  Ensure the input is a properly structured list so each item is processed individually.
