We are having a problem with a workflow getting stuck at a Request Data action. 99% of the time, this action completes successfully and the workflow moves on to the next action. Once in a while however, although the workflow history shows that the task status is Completed, the workflow outcome remains at Pending forever:
We are using SharePoint 2013, which is up to date, and Nintex Workflow and Forms 2013 which are also up to date.
The Request Data action has a Nintex Form within it. LazyApproval is disabled; users respond only via desktop, no mobile. The task is assigned only to one individual, using a previous set variable action. There are no reminders, and no escalation. It uses an existing (custom) content type. Variables are provided to receive the data for each content type column:
There is also a Set Item Permissions action, prior to the task, which grants the user-to-be-assigned Full Control access to the item the workflow is running on. Existing permissions are not removed.
The person who was assigned the third task in the first screenshot, where the workflow has gotten stuck, has been assigned this Request Data task before, on a different item, and the workflow completed successfully. There are other users where the workflow has gotten stuck as well, who have also had the workflow complete successfully on other items.
What are some possible causes for this please? Is there any way to force this workflow to continue? How can we prevent this from happening?
P.S. @emha here is the new post you suggested I write
