Actually, this should be fixed in ansys-tools-visualization-interface

[germa89]

I have the feeling that ansys-tools-visualization-interface (from now on, ever, I will refer to it as the VI or ATVI) is injecting some actors in the plot that do not have datasets. I didn't know this was possible.

As I suspected, there are the following objects:

There are two objects, one is a polydata object (fine) and another one is an scalar bar actor and does not have this data.

@AlejandroFernandezLuces can you give me some code that plot that kind of vtkScalarBarActor? So I can replicate it in pyvista repo and propose a PR.

Not needed since Pyvista already fixed it. #209 (review)
