Assign User - (Specified user does not exist or you do not have required permissions)

Question

I wish to use the Assign User action in automation using a smart value

This smart value comes from a cascading list.

The value appears valid in the log for debugging  'First Last'

The assign issue action in the log shows

(Specified user does not exist or you do not have required permissions)

Not an answer but continuing how to resolve.

Created a new user that belongs to the group and is a part of the Service Desk Team role as indicated by the above picture.  Assigned that user to be the Actor for the automation rule.

Initially the automation rule would fail on Re-Fetch the issue after Delay.

Added user to Administrators role and that cleared the Re-Fetch issue.

However, it still fails the Assign User in automation

I think I see it now.  The automation bot doesn't have the right permissions.

I trying to assign case via account id.

I can assign manually via the console, but would like the automation to do the work if the reporter selects the user.  That selected user is NOT using the ASSIGNEE field but rather a custom field using a cascading select list because the ticket could be assigned to a group for assignment later.

Here are my current permissions.
