One thing I didn’t realize at first is that filter type does not require a value and the ScheduleFilter.ByFieldTypeAndValue node is not set up to handle those types of filters.
The post here should help resolve your issue. With this code you have to input the schedule and the name of the field. This automatically adds the filter to the schedule, so you don’t feed the output into the ScheduleView.AddFilters node.
You will also have to edit the part of the code circled. Change that to what you want your filter type to be after the period. “HasNoValue” or “HasValue”.
