Web console error after idle time

As seen on another IdB5 lab implementation today - may not be the same error exactly, but this is the same scenario (page left idle for 24 hours or longer):

Error

System.ArgumentException: The parameters dictionary contains a null entry for parameter 'connectorId' of non-nullable type 'System.Guid' for method 'System.Threading.Tasks.Task`1[System.Web.Mvc.ActionResult] ConnectorDetails(System.Guid)' in 'Unify.Connect.Web.ConnectorController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.

Thanks, Bob. Added to the backlog.
