Hello,

I am having the next error message while trying to run a programmable filter more than one time in a session. What I find estrange is that if I run my programmable filter only once it works fine but when I step to the next file it gives the error (I am on paraview 5.10 on Linux):

* * *

Traceback (most recent call last):  
File “”, line 22, in   
File “”, line 20, in RequestData  
File “/home/softs/softs/ParaView-5.10.1-MPI-Linux-Python3.9-x86\_64/bin/…/lib/python3.9/encodings/ascii.py”, line 26, in decode  
return codecs.ascii\_decode(input, self.errors)[0]  
UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xc2 in position 23007: ordinal not in range(128)

Thanks very much

Juan
