I have created a SharePoint2013 Site Workflow for a document library. In the workflow, I am trying to get values from "Created By" or "Author" column of the document library and display it in the "Log to History List" of the workflow. After running the workflow, I am getting blank / no values displayed for the column. However, I can get values from other columns like Title and display it in the workflow history.
Am I missing anything?
