Diagnoses

K2 for Sharepoint workflow is set to notify the Originator when they get a task item. They are not receiving the task notifications, but email events seems to be working. The Windows Application event shows:

An error has occurred: System.Exception: Could not load file or assembly 'bINSTALLDIR]Host ServerBinSourceCode.EventBus.EventAssemblies.dll' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)
at SourceCode.EventBus.Server.EventQueueProcessing.ExecuteAssembly(Int32 CustomEventInstanceID, Int32 CustomEventID, ResolvedPolicyMapping resolvedPolicyMapping, Boolean isConditional, Int32 eventTypeID)
at SourceCode.EventBus.Server.EventQueueProcessing.ProcessEvent(Int32 ID)
 

Resolution

Verified and performed the following:

1.In SourceCode.EventBus.Server.config update mailassembly and mailassemblytype pointed to the wrong .dll

a. Update the mailassembly to point to iDrive letter:]Program Files (x86)K2 blackpearlHost ServerBinSourceCode.EventBus.MessageBusRecorder.dll instead of eINSTALLDIR]Host ServerBinSourceCode.EventBus.EventAssemblies.dll'

b. Update to point to SourceCode.EventBus.MessageBusRecorder.MessageBusMailer instead of SourceCode.EventBus.EventAssemblies.Mail

2.On the DB:
:Please contact K2 Technical Support for assistance in updating the DB directly.]

Restarted the K2 blackpearl service and tested that task notification is now working.
