Array Aggregator – can’t find “Map / + Add item” in Aggregated fields (UI shows only checkboxes)

Hi everyone :waving_hand:

I’m using Flow Control → Array aggregator to collect rows from Google Sheets → Search Rows [19] and output a custom structure (e.g., name, class, meal).
The module is set to Target structure type = Custom.

Issue
In the Aggregated fields section I only see checkboxes for existing fields. I don’t see any way to switch that panel into mapping mode — no “Map” toggle and no “+ Add item” button for defining my own fields.

From docs/community examples it looks like I should be able to switch Aggregated fields into a mapping view when using Custom and then add items (or, alternatively, use the JSON approach). Can you confirm the current, expected UI/flow?

  • Make Help – Flow control / Array Aggregator (mentions how Target structure and customization work). help.make.com

  • Community notes referring to a tiny “Map” toggle in the Aggregated fields header that enables + Add item. Where exactly should that appear in the new UI? Make Community

Questions

  1. Is the Map / + Add item control still present for the Array Aggregator when Target structure type = Custom?

  2. If yes, where in the panel should it appear in the current UI, and how can I force switching to that mode if it’s hidden?

  3. If the recommended pattern now is to select a JSON → Create JSON array in Target structure type and do the field mapping there, please confirm that this is the best practice. help.make.com

I can provide screenshots and Scenario/Run IDs if needed. Thanks! :folded_hands:

Hi @Harel_khafi

The community notes you mentioned is not a valid method, there is no such option with the Aggregator. The user had copied the suggestion from Chat GPT, as you may know these responses are usually inaccurate.

Yes, the Create JSON method can help you create your desired aggregated fields for the aggregator.
The Aggregator should precede the Create JSON module.
After setting these up, if the JSON structure does not appear in the aggregator as a target module, do this:

  1. Unlink the Create JSON module.

  2. Run the scenario normally up to the aggregator module

  3. Connect the Create JSON module back to the aggregator and try to select the target structure again.

    Not sure of the logic why it works this way but it is what it is.
    Let me know if it works.
