Hi Team,

I am trying to remove all out of sync workflows from my SharePoint environment. I am using below command to execute for all the site collections where NW feature is enabled.

                             .\NWAdmin.exe -o SyncTerminatedWorkflows -url http://siteURL

But there are few site collections where i get below error. I want my script to continue with the remaining sites whenever we get error. Can you suggest how can i deal with this? Also what is the reason behind below error?                           

 

Error!

System.NullReferenceException: Object reference not set to an instance of an object.

   at Nintex.Workflow.NWAdmin.SyncTerminatedWorkflows.CancelWorkflow(SPWeb web, Guid instanceId, String category)

   at Nintex.Workflow.NWAdmin.SyncTerminatedWorkflows.Execute()

Continue processing?

 

Thanks & Regards,

Simran
