https://gitlab.kitware.com/vtk/vtk/-/merge_requests/9727 introduced a new file to the `web` module: `Web/Python/vtkmodules/web/errors.py` This file appears not to be shipping in the distribution. Causing a failed import: ```py >>> from vtkmodules.web.protocols import * Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/opt/miniconda3/envs/pyvista-dev/lib/python3.9/site-packages/vtkmodules/web/protocols.py", line 12, in <module> from vtkmodules.web.errors import WebDependencyMissingError ModuleNotFoundError: No module named 'vtkmodules.web.errors' >>> ``` When I inspected the files installed from the wheel, indeed the `errors.py` file was missing. This is quite odd. Did we forget to add the file to a manifest or something? cc @ben.boeckel @sebastien.jourdain
