Retrieving id from profile.timeSeriesEvents.identityMap in AJO offer

Question

Hi everyone,

I'm wondering if anyone had successfully retrieved Id from profile.timeSeriesEvents.identityMap in an AJO offer.

I had no problem retrieving the id using this helper function. {%= head(get(profile.identityMap,"accountId")).id %}

However, when I use the same formula for profile.timeSeriesEvents.identityMap:

{%= head(get(profile.timeSeriesEvents.identityMap,"accountId")) %}, it throws this error:

Invalid syntax get applied to an array requires integer parameter - was: STRING., Object expression for "head" must be of type array. Was Map[STRING => OBJECT[]].. Error beginning at position: Line 5, Character 23

Appreciate any tips on this.

yes there are certain limitations when using profile.timeSeriesEvents (and its fields, like identityMap). just thinking it may be due to limited support for iterating or calling deep-access helpers on collections/arrays within offers.  https://experienceleague.adobe.com/en/docs/journey-optimizer/using/content-management/personalization/functions/arrays-list

@frankxu3 profile.timeSeriesEvents is an array of event objects, each with its own identityMap. profile.timeSeriesEvents.identityMap means: "the array of identityMaps for each event" so it’s actually an array of maps, not a map by itself.

try this:

select the first event, then access its identityMap:
```
{%= head(get(head(profile.timeSeriesEvents).identityMap, "accountId")).id %}
```
- head(profile.timeSeriesEvents) — gets the first event object
- .identityMap — gets that event's identityMap
- get(..., "accountId") — gets the array for "accountId", e.g. [{"id":"xxx"}]
- head(...).id — gets the first id
