Question asked by venkadeshb@gmail.com on May 31, 2017

We are using Nintex Workflow (Reusable) in our application. The workflow has associated to many list using content type. If we select an item and try to view the "View workflow history" it shows the completed and errored out workflow however if we try to view the "Workflows" we get "Sorry, something went wrong. An unexpected error has occurred". we check the logs from the server and attached the logs below.
