ParaView Support

Hi Community,

I am having a challenge loading a .vtp file in Paraview. The attached .vtp file below has 6 Polygons, their corresponding points and cells. The mesh loads correctly when I ommit the CellData tag, however, the following error occurs when I try to assign a scalar or vector to each cell. Could anyone assist with check what could be wrong with the simple .vtp file below that I generated. Thanks in advance.
