AttributeError: 'PVModule' object has no attribute 'XMLHierarchicalBoxDataWriter'

Hi,

I have three, possibly related, questions.

I pass a vtkNonOverlappingAMR object to Catalyst-v5.6.0. Using feslicescript.py, I am able to extract a slice in vtm format.
Q1: How to save the slice as a .png image?

Q2: I cannot figure out how to extract the mesh. allinputsgridwriter.py and gridwriter.py, both end with the same error:

AttributeError: ‘PVModule’ object has no attribute XMLHierarchicalBoxDataWriter’.

Q3: How to plot over a line?
I tried “plotOverLine1 = PlotOverLine(Input=paramesh_chombo_0050h5,
Source=‘High Resolution Line Source’)”, but got ‘PVModule has no PlotOverLine’ (or something close).

I guess that the issue is in in my build of Catalyst-v5.6.0-Base-Enable-Python-Essentials-Extras-Rendering-Base on Linux. I did not get any errors or warnings, though.

Could you advice how to troubleshoot these issues, please?

Thanks,
Ted
