INVALID_PREDICATE_ENUM_VALUE - can't filter budgets from BudgetService

         Dim service As BudgetService = CType(User.GetService(AdWordsService.v201607.BudgetService), BudgetService)

        Dim selector As New Selector

        selector.fields = New String() {

           Budget.Fields.BudgetId, Budget.Fields.Amount

        }

        selector.predicates = New Predicate() {

            Predicate.Equals(Budget.Fields.BudgetStatus, BudgetBudgetStatus.ENABLED)

        }

        selector.paging = Paging.Default

        Dim page As BudgetPage

        Try

            ' Get the text ads.

            page = service.get(selector)

error: INVALID_PREDICATE_ENUM_VALUE, trigger: '0'

How can the enum have an invalid value?  Is the BudgetBudgetStatus ENUM not the correct enum for filtering BudgetStatus?
