"JSON parsing error" when connect to a remote pvserver

When I try to connect to a pvserver on my desktop, the paraview shows the following message:

ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\Rendering\RayTracing\vtkOSPRayMaterialLibrary.cxx, line 280
vtkOSPRayMaterialLibrary (000001E494FFF170): JSON parsing error: * Line 1, Column 1
Syntax error: value, object or array expected.

Though it does not affect the functions, it a little annoying.

By the way, I am using the paraview 5.9.0 on windows and try to connect to pvserver on a red-hat linux.

Thanks for your report, that’s a known issue with a fix under review.


Thanks for your quick reply.
