Error message for clip or slice in a saved state

Whenever a clip or slice is applied to a netcdf-volume and the state is saved, an error message appears when opening the state:

ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\Common\ExecutionModel\vtkDemandDrivenPipeline.cxx, line 760
vtkPVDataRepresentationPipeline (0000023D15BA3CB0): Input for connection index 0 on input port index 0 for algorithm vtkImageSliceRepresentation(0000023D15DEC140) is of type vtkRectilinearGrid, but a vtkImageData is required.

Everything renders fine and as expected, the error message apparently has no consequence.

Example data can be found here: https://discourse.paraview.org/t/error-message-for-clip-or-slice-in-a-saved-state/9710

Note: Any rectilinear grid will cause this issue, even .vtr files.
