I am using NINTEX workflow for SharePoint (Version 2010).
I have a site workflow which picks up a xml file from a SP list. This xml file is used to retrieve the data and create an email template. Subsequently, we send a notification to the intended recipients and delete the control file from the list using the "Delete Item" action. However, sometimes the workflow errors out with the following error: "The workflow could not delete the list item. Make sure the list exists and the user has permissions to delete items in the list." All the intended users that are initiating this workflow have contribute rights to the SP list and should be able to delete the item. This is an intermittent issue and doesn't occur every time this workflow is executed.
Please can you suggest any remedial action to over come the error.
