We recently upgraded from SP2010 to SP2013.
I need to edit an existing list workflow. I know it exists because it's been working, but when I try to edit it, I'm getting "Error Cannot find workflow in repository".
Specifically, if I go to Site Settings > Nintex Workflow > Workflow Inventory I see it listed but the "Last Run Time" is blank.
If I then click on the workflow name I get an error "Unable to preview workflow"
If I then click on "Edit workflow" I get an error "Cannot find workflow in repository"
I do know that the workflow exists and runs because if I view "workflows" for a list item I see the history and results:
This is for a "Picture Library" app (list).
Both the list and workflow existed before the upgrade to SharePoint 2013.
Would appreciate any help in recovering the workflow so that I can edit it and/or use it as a guide for recreating it.
