Error while creating word document using Sys.OleObject

def Word_test():
  Word = Sys.OleObject["Word.Application"]
  Log.Message("Opening Word and making it visible")
  Word.Visible = True
  #Opening up a new doc
  Word.Documents.Add()
  #activated doc and adding some text
  Word.ActiveDocument.Content = "Here is some text"
  #saving as a new file
  Word.ActiveDocument.SaveAs("C:\\Users\\justin.kim\\OneDrive - SmartBear Software, Inc\\Word_TC_test.docx")
  Log.Message("Shutting MS Word down")
  Word.Quit()

So the error message you are getting is telling me that you have not yet created a word doc with that name. 

If you are choosing to create a file, then you must save that file first. Although the (Python) syntax above is different, the order in which I used the methods are the same.
