Hi, I have a requirement where a Rest call is returning a response payload with repeating items. I now am trying to send the details in an email, the body of which will contain all the repeated items. The issue is when i try to map this repeted group element within a template parameter, I get an error due to repeated nodes. Is there any way to show the entire data from all repeating nodes in the email body?
