Accumulation to List

Converts an ACCUMULATION object into a standard list. It extracts the internal sequence of items from the accumulation container and returns them as a plain list, preserving order. If the input is invalid or empty, it returns an empty list.

Usage

Use this node when you have been collecting items with accumulation-based nodes and need a native list for downstream operations such as iteration, selection, transformation, or output. Typically placed after nodes like Accumulate or List to Accumulation to expose the collected items as a list for further processing.

Inputs

Field	Required	Type	Description	Example
accumulation	True	ACCUMULATION	The accumulation container holding a sequence of items under its internal storage. Usually produced by Accumulate or List to Accumulation nodes.	ACCUMULATION object produced by Accumulate (e.g., {"accum": ["item A", "item B", 3]})

Outputs

Field	Type	Description	Example
list	*	A standard list of the accumulated items. Items are returned in insertion order.	["item A", "item B", 3]

Important Notes

• This node returns an empty list if the input is not a valid ACCUMULATION or has no items.
• Item order is preserved from how they were added to the accumulation.
• If earlier accumulation steps skipped None values (per their logic), those None items will not appear; this node itself does not apply additional filtering.
• The output type is wildcard (*) but practically represents a list of items that may be of mixed types.

Troubleshooting

• If the output is an empty list unexpectedly, ensure the input is a valid ACCUMULATION and contains items (verify upstream nodes like Accumulate or List to Accumulation).
• If downstream nodes expect a specific element type, ensure earlier steps added the correct types to the accumulation, since the list may contain mixed types.
• If you see unexpected items, check upstream accumulation logic to confirm None-skipping or other behaviors that may affect collected items.
