VTKm Treshold, Clip, Contour does not support certain type of data array

When using VTKm Treshold, Clip or Contour, certain type of data array are unsupported :

How to reproduce :

  • Open ParaView
  • Create a wavelet, Apply
  • Add a random Attribute, set Attribute type to type, Apply
  • Add a VTKm Treshold

With type in Unsigned Long, Long, Char, it segfaults.

With type in Unsigned Int, Unsigned Short, Short, it show an error like
