Desinger Workflow Error as Item not not

Dear All,

            I have written Designer Workflow for Pausing a uploaded document  for 365 days then moving to sub-site and deleting the document from document library .When time comes to delete the document after pausing for 365 days and moving document to sub-site it is showing Error Occurred as"Item not Found". Then I clicked on "Error Occurred" and showing below info.I would like to know weather this workflow has moved automatically or moved by user "White".Can any one help me for what purpose the user white name has taken place here.
