The workflow has ended unexpectedly. An error has occurred in [x].

Jump to solution

I have a few workflows in three different site collections which are erroring or failing with this email notification. The workflow details are all green and it shows the workflow fully completed successfully. The workflow actions result in perfect data -- nothing is missing or incorrect. This is the email I get:

 

     "The workflow has ended unexpectedly.

     An error has occurred in .

     Click here to view the workflow status."

 

I opened a Nintex support ticket just now, however I'm wondering if anyone else has a solution? I saw a similar issue thread here, but it looks to be slightly different: https://community.nintex.com/message/22534#22534

 

Thanks!

Allan

Hi Andrew,

 

Thanks for your reply! We were able to resolve it without Nintex Support. I also forgot to mention a few details in case this helps someone in the future:

 

Symptoms:

  1. This happened to a site workflow, not a list workflow.
  2. As far as workflow actions go, I have zero delays/pauses/”wait-until” in the workflow. However, the error is generated with a time stamp that's 1-2 minutes after the entire workflow completes successfully (i.e. after all workflow actions are completed). It always errors at the end.

               Time: 11/13/2015 1:47 PM

               Event: Error

               Message: An error has occurred in [workflow name].

               Outcome: (empty)

 

      3. See the ULS logs below. This is the error: "List does not exist.  The page you selected contains a list that does not exist.  It may have been deleted by another user."

 

 

Solution:

  1. In a nutshell, the fix was to add the workflow action called "Commit pending changes" inside one of the For Each loops. A colleague had a hunch that "Commit pending changes" could resolve it. To test the hunch, I added the action after every variable or update action in the workflow, and then narrowed it down to just one spot in the workflow.

Thank you very much Allan, your answer was able to resolve an issue which just wouldn't go away. My list workflow was working correctly when started manually.The issue was that when it was started automatically all the actions would show up as green indicating that all the actions had been performed but then I would still get a message stating that an error has occurred. It was just an extremely annoying and frustrating error which I struggled to resolve until I found this post. Thanks for sharing your insight.
