Dear Paraview Community,
I am having problems loading the following data in Paraview that contains direction dependent degrees for a VTK_LAGRANGE_QUADRILATERAL.
<VTKFile type="UnstructuredGrid" version="1.0" byte_order="LittleEndian" header_type="UInt64">

Reading the mesh works in Paraview 5.9.1 and fails in Paraview 5.10.0 (and later versions) with the following error message.
( 4.656s) [paraview ]vtkHigherOrderQuadrilat:598 ERR| vtkLagrangeQuadrilateral (0x1ca4dd90): The degrees are direction dependents, and should be set in the input file.

Did something change with how to specify the degrees of the cells? I am using HigherOrderDegrees CellData. I check the release notes for Paraview 5.10 but didn’t see any discussion of this.
Thanks for any help you can provide,
Lucas
