Error: Unsupported data type: 1

Hello,
I have a VTK file containing Structured_Grid data of dimensions 64641. when I import the file in Paraview and run, it shows the following error:

"ERROR: In /opt/glr/paraview/paraview-ci/build/superbuild/paraview/src/VTK/IO/Legacy/vtkDataReader.cxx, line 2025

vtkStructuredGridReader (0x7fdd1f486a40): Unsupported data type: 1".

I am wondering what is wrong and how I can possibly solve it. The only thing that came to my mind is that the third column of my are all zeros, and based on the PARAVIEW document, for the structured-grid data the values should be more or equal to 1. Could this be a possible issue?

A part of my data:
