Hi,

 

I am having issues with sharepoint K2 integration lately. But I managed to reslove all the issues except for one, after I uninstall and re-install K2 app in site collection.

My only issue currently I am having is, whenever I upload a document in library my workflow which supposed to kick off is not working. Other Sharepoint smartobjects were able to communicate with that library and i am able to execute all the methods successfully on that Library.

When I looked at hostServer logs, I got the below:

0 SharePointRoleProvider.GetContainers: System.Reflection.TargetInvocationException: An unexpected failure was encountered when contacting SharePoint to get information from the group provider "My Group Name": Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
at SourceCode.Security.Providers.SharePoint.TempPrincipalParser.get_ExclusionSet()
at SourceCode.Security.Providers.SharePoint.Shared.SPCsomClient.SourceCode.Security.Providers.SharePoint.Shared.ISPGroupProviderClient.GetContainers(IEnumerable`1 identities)
--- End of inner exception stack trace ---

 

I looked at HostServer.Groupprovider table and everything looks fine.

Sharepoint Version : Online

K2 - 4.7

Any suggestion/Solution is appreciated.

Thanks.

Hi  @AnandVenkat1 ,


 


Could you check whether the SharePoint group in the error message has the permissions to start the workflow? 


 


To Start and View a workflow you need to configure the following:


In K2 Management, go to the Workflow Server node, and then Workflow, and select the workflow. Select Rights and assign Start and View rights to the user.


In SharePoint:




  • App Catalog: Read



  • SharePoint site: Read

  • SharePoint site: K2 Solution Participants (Legacy)

  • Group: Read


  • SharePoint lists and libraries: Read and Edit permissions for users as required by the functions performed by the application on the SharePoint Lists and Libraries




 


 


Cheers,


Kimberly
