[Paraview] vtkPVTrivialProducer issues

[wastrel at gmail.com]

I simplified the code and tried it on Paraview3.8.0. It reads in a vtu file,
fetch the data and then write it back to a new file. But still got errors as
follow.

Script:

from paraview.simple import *
from paraview.simple import servermanager as sm
from paraview import vtk

# connect internally
connection=sm.Connect()

# Set the pvpython path
INPUTFILE="test.vtu"
OUTPUTFILE="tested.vtu"

# create a reader
reader=sm.sources.XMLUnstructuredGridReader(FileName=INPUTFILE)

# get the data i.e moves data from the server to the client
data=sm.Fetch(reader)

tp=sm.sources.TrivialProducer()
obj=tp.GetClientSideObject()
obj.SetOutput(data)

writer=sm.writers.XMLUnstructuredGridWriter(DataMode=2,FileName=OUTPUTFILE,Input=obj)

writer.UpdatePipeline()


Errors:

getting appended
vtkReductionFilter : [ ...........]
Traceback (most recent call last):

Any clues?
