[Paraview] Reading PLOT3D into Paraview (Paul Edwards)

Hi,
I have the same error.
For myself, this message occurs when I read the geometry alone, without
the results file.
Nevertheless, I can display the geometry.
I guess it reports there is no results file in input.
It appeared with version 3.98.
There is no message if I read geometry + results file at the same time
Best regards
Joëlle
