I am trying to set the user in Azure DevOps by using an email address passed in with the payload.

I have tried nodeHelper.getUserByEmail however, it returns nothing to workItem.assignee.

This is to set the assigned to value.  I put in a debug command to stop the script so I could verify that the email value is there and it was.  Additionally, I have verified the user connected to Exalate has permissions to do this work.
