Step type send email does not accept expression and returns Invalid Email in To or CC

Good afternoon,

I tested this expression:

"GetUser($currentPortal, LastRunner($Job, "<step ID>"))['email']"

and it works.

But when I add it to an email step in the text box To or CC it does not accept the value and shows a message "Invalid email".

I see that you have already wrapped the arcade expression in double quotes.
According to ESRI documentation, the To/CC fields accept expressions only when inserted via the “This input supports Arcade Expressions” option; otherwise, they’re treated as plain text and flagged as invalid.

In practice, the reliable workaround is to resolve the value first (e.g., store the email in a job property) and then reference that property in the Email step.

Found the issue.

The expression must start and end with double quotes, and use single quotes inside the expression.

"GetUser($currentPortal, LastRunner($Job, '############'))['email']"
