SOLVED With this expression I return the desired email domain from the profile's email list Object:#{ExperiencePlatform.ProfileFieldGroup.profile.identityMap.entry('email').first(containIgnoreCase(currentDataPackField.id, 'adobe.com')).id}

SOLVED: If you have this issue open a ticket to Official support. It's a backend issue they solve. Regards.

Thanks! please take a look to my response to ZoeKi.

thanks! but I need the string value, for example, "a@asd.com", not a boolean. The use case is that I need to send that string to Slack using custom action, that's why I need the exact value and not the boolean.    

Hi, any solution for this?

not sure if I'm understanding well but I mean creating a streaming audience with profiles who received that email, so then in journey, add that audience in a condition just like "not in (AA audience)" just before the email so that profile won't receive the email.

Using a streaming audience and add it in a Condition?

ok! client is asking if there's something like this in AJO when publishing or triggering a delivery (client is using ACS at this moment): 

Hi, I'd like to know if errors when triggering an API campaign are stored in AJO just as Adobe Campaign Standard showing in UI any error. For example I'd like to see somewhere in AJO the 404 error detail.  Is it possible? 

any help?
