InvalidOperationException UpdateXml Action

Question asked by mahendrent on Mar 17, 2015

I have a workflow that triggers on create when a user submits a document to a library (InfoPath).

 

The workflow has actions enclosed in an Action Set set to run as the workflow owner (a user with full control permissions).

 

The first action is Set Permissions which gives the Initiator "ViewOnly" permissions.

This is followed by a Commit Pending Changes action.

 

These two actions have been working correctly for the past year.

 

I had to add a Pause for 5 Minutes action, followed by an UpdateXml action at the end of the workflow, which updates a processing instruction text to relink the InfoPath form. I even "caught the errors" for the action using the Error Handling section.

 

The problem:

The workflow runs correctly 60% of the time, and crashes with System.InvalidOperationException the remainder, even when I handle errors.

 

The event log on the Server shows the following:
