Map() function can't access Array Aggregator fields - returns empty output

Hello everyone! I REALLY need your help.
I’m trying to use map() to iterate through an Array Aggregator output but cannot access the specific fields within each array element.

Setup:

Issue: Array Aggregator creates the array correctly, all the 4 outputs bundles are there when checking the individual module, but afterwards, all map() attempts in the Telegram Message module return a completely empty output:

My trys:

join(map(12.Array[]; 1.Tarea (C) + " → " + 1.Persona (D)); newline)
join(map(12.Array[]; 1.2 + " → " + 1.3); newline)  
join(map(12.Array[]; 1["2"] + " → " + 1["3"]); newline)

A couple of screenshots of the different ways I’ve tried (listed above):

Captura de pantalla 2025-08-27 a las 13.37.28

Captura de pantalla 2025-08-27 a las 13.39.17

All of them get a completely empty output.

Also, when I used this:

  • join(map(12.Array[]; 1); newline)

  • I got this result:

  • {object}1{object}1{object}1{object}

**
But raw array output shows data exists:** {{12.Array[]}} returns:

Captura de pantalla 2025-08-27 a las 13.40.45

So,

What is the correct syntax to access specific fields within an array generated by Array Aggregator using the map() function in Make.com? The fields appear as numeric properties (“2”, “3”) in the raw array output. What I’m doing wrong?

Technical Configuration:

  • Array Aggregator: Custom target structure, Tarea (C) and Persona (D) fields selected, Group by empty

  • Array contains 4 valid elements according to IMTAGGLENGTH: 4

    Thank you for your help. Already 2 days stuck hours in this!

Hi @Mikk

Have you tried the Text Aggregator instead of the Array Aggregator?

You can use something like this as the Text:

{{11.Tarea (C)}} → {{11.Persona (D)}}

Also, click on Show advanced settings and choose New row as Row separator.

He @damato thanks a lot for your answer!
It was exactly what the solution was…so simple to solve it with Text Aggregator instead of Array Aggregator.
Now it looks like this and works perfectly!

Haven’t tried the New Row yet but will do later on, just saw it as you said in the Advanced Settings.
At first I thought it was in the functions box, atm I put NewLine function and also does the work.

THANKS A LOT FOR YOUR ANSWER!
Really appreciate this!
Best energy to you,

Miq
