Smart Value for assignee name doesn't work

[ArkSigner Admin]

I'm using smart value in automation for showing assignee name in a teams message. When I try for reporter's name its working however its not working for assignee name

Hi @ArkSigner Admin 

Is the Assignee specified on the issue, as it seems it is not? Issue details in the teams message support this asumption

Assignee: Unassinged

The rule is working and the message in teams is working as well. 

If the issue has no assignee, the default assignee is "unassigned".

This unassigned value is a default in Jira, this is no a user, it doesn't have a Display Name. Assign the issue to your self and see the result.
