Thanks for the replying to everyone.
The Node ScheduleFilter.AddFilter requires the value parameter as a string or a number (depends on a filter type).
And I have just understood my error. Explain it here, maybe it will help to somebody.
I am trying to set a value in filter in mm. This returns an error.
But if I set a value in ft, a schedule filter will be created. Everything works.
4500 mm = 14,76378 ft.
So, what’s the maximum number parameter value for schedule filter?
It’s 9144000 mm = 30000 ft.
And a very important feature.
A number value must have a fraction or the tailing “.0”.
This is why I have gotten an error, when trying to set “4500”, not “4500 .0”.
Also, the standart input node also returns a number with no fraction. This makes an error too.

The problem is, seems, that the node ScheduleView.AddFilter wants only Double type as a value parameter (when creating a number filter).
Thanks to everyone
