AJO Advanced Expressions – extracting attribute from latest object in array

I have an array of objects and need to:

1. Identify the object with the latest timestamp
2. Return only that object
3. Access a specific attribute (e.g. email) from the selected object
4. Use that value in an AJO journey condition

===========================================================================

🔹 Sample Data

!--scriptorstartfragment-->

"productDetails": [

  {

    "id": "product-001",

    "timestamp": "2026-04-23T02:00:38.000Z",

    "email": "email-001@nomail.com"

  },

  {

    "id": "product-004",

    "timestamp": "2026-04-23T02:30:38.000Z",

    "email": "email-004@nomail.com"

  },

  {

    "id": "product-002",

    "timestamp": "2026-04-23T02:10:38.000Z",

    "email": "email-002@nomail.com"

  },

  {

    "id": "product-003",

    "timestamp": "2026-04-23T02:20:38.000Z",

    "email": "email-003@nomail.com"

  }

]

===========================================================================
I was able to filter the objects based on the latest timestamp using filter() and max():
!--scriptorstartfragment-->

filter(

  #{ExperiencePlatform.ProfileFieldGroup.productDetails},

  "timestamp",

  [max(#{ExperiencePlatform.ProfileFieldGroup.productDetails.timestamp})]

)

This correctly returns the object with the latest timestamp.

===========================================================================

Expectation : Access an attribute like .email from the filtered result

Expected Output : email-004@nomail.com
