Hi,
I am trying the ParaView Omniverse connector to generate scene that use the volume rendering. Each time when I try to switch to the volume representation, my ParaView crash and close automatically. Everything works normally if I am not using the Omniverse connector view. I just make a test using the wavelet example and below is the error message shown when my ParaView crash.

May I ask for some help to solve this problem or is it a known bug that is not solved yet? From the error message, I see it mentioned about the data type has a mismatch in floating point precision, is there something I can corrected it?
