Hello,  
I get following error message whenever I use the VCR buttons in the toolbar section:

```auto
Generic Warning: In /home/buildslave/dashboards/buildbot/paraview_release-pvbinsdash-linux-shared-release_superbuild/build/superbuild/paraview/src/VTK/Common/Core/vtkAbstractArray.cxx, line 428
Unsupported data type: 0! Setting to VTK_DOUBLE

```

I can still use filters or select data, so the animation itself is fine.  
Do you have any suggestions?

When I use the old version of Paraview :  
5.4.1-822-g597adef 64-bit  
The animation works fine and no error occurs.  
However with the new version:  
5.8.1  
I have the mentioned problem

Thank you in advance

This is only a warning, not an error. You have some issues within your data, the type of arrays is not correctly defined and VTK fallsback to using double, which is fine.

You can ignore it, but you should fix your files or file generation.
