Hello Everyone,


I have a requirement that that updates a "Published Date" field that is part of a Content Type and part of the Document Information Panel (DIP).

We currently have a WF that sends out and Email when a user "Publishes" a document, the WF runs only if the Version of the document end in .0. 

The user is responsible for making sure that they update the "Published Date" before the "Publish" their documents but most of them forget to do this step.

I wanted to work this step into my WF.  Using SharePoint 2013, Nintex Workflows 2013


I added the "Update Document" Action into my WF.

Source: Current Item

Content Control Title: Published Date

Value: Current Date

I also tired a Variable that was set up to today's date.

Preserve Formatting Checked

Output: Current Item


This Document Library has Check In/Out enabled .


When I ran the WF I received the Following Error message:

Error updating document. Expression must evaluate to a node-set.


Any ideas on what this message means?
