As of today I am suddenly getting unexpected errors when opening some workflow actions. This is occurring across ALL existing workflows and when creating new workflows. We have tracked down the error associated with one of the Correlation IDs (see attached).
It mentions something about a duplicate attribute name. Would this be found in a sharepoint xml or a nintex xml? I really don't know where to begin looking as I am not a sharepoint admin. But if I can give the sharepoint admin some direction we may be able to resolve the issue.
Has anyone come across this before?
