I tried to aggregate the 3 items (json format from LLM output parser) into a 1 items (or 1 single table with 3 rows). I am not able to achieve this using the Aggregate Node (All item data into single list). Instead I may only get 1 item but only 1 (latest) row or it will output 3 items.
Do you mean you need to aggregate the results after ALL iterations of the loop are done? If so you may want to use the ‘Done’ branch of the Loop over Items.
