I am using Rheolef, which calls Paraview to render meshes. At one point, the script (which can be found [here](https://gricad-gitlab.univ-grenoble-alpes.fr/rheolef/rheolef/-/blob/master/main/vtk/paraview_rheolef.py?ref_type=heads)) calls (line 160) the function CreateScalarBar of the simple module, which calls (line 1982) the Register method of servermanager, which is not implemented. Therefore, I get the following error:  
AttributeError: module ‘paraview.servermanager’ has no attribute ‘Register’

How can I deal with this error in order for the rendering to work ?

**Environment**  
Ubuntu 22.04, installed Paraview using APT sources (python3-paraview and paraview)  
paraview version 5.10.0-RC1
