Hello all,

For some reason event coordinators are not being notified, via email, when there is a registration for their events. But this exception is being logged every time someone registers.

Global.DrainTransactionQueue(): sendRegistrationNotifcationTransaction
at RockWeb.Global.LogError(Exception ex, HttpContext context)
   at RockWeb.Global.DrainTransactionQueue()
   at RockWeb.Global.b__1c()
   at System.Threading.Tasks.Task.Execute()

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)
   at System.Threading.Tasks.Task.ExecuteWithThreadLocal(Task& currentTaskSlot)
   at System.Threading.Tasks.Task.ExecuteEntry(Boolean bPreventDoubleExecution)
   at System.Threading.ThreadPoolWorkQueue.Dispatch()

System.InvalidOperationException     mscorlib    Nullable object must have a value.

   at Rock.Transactions.SendRegistrationNotificationTransaction.Execute()
   at RockWeb.Global.DrainTransactionQueue() in c:\inetpub\wwwroot\App_Code\Global.asax.cs:line 1055

The registrant still gets a confirmation email though.

Any thoughts would be appreciated,

Thanks!
