I am running GP 2015 R2 workflow and got a new error after upgrade that was not there before R2!
The error appears when users approve a document even though the document get approved!
The error is:
"[Microsoft][SQL Server Native Client 11.0][SQL Server]A.NET Framework error occurred during execution of user-defined routine or aggregate "GetAssignedUsers". System.ArgumentNullException: Value cannot be null.Parameter name: UsersListGuidSystem.A
Any advice to solve this issue?
