ParaView failed to open OBJ with Texture

ParaView Support

Hello, I am trying to import an obj with texture to ParaView GUI. I followed this thread and created ParaView state file (pvsm) by running the python script in pvpython. When I run this script, it creates some vtp and json files in a directory without any error. However, when I load pvsm file from the ParaView menu File>Load State, it gives me the following error and does not show anything in the viewer.

Not sure why but these paths should be absolute, not relative. Can you check if they are absolute in the .pvsm file ?

The paths look relative to me in .pvsm file. I am uploading the .pvsm file as well, please correct me on what I am doing wrong.

Here are my test files to reproduce the error.

Your statefile should contain absolute path, not relative path. How do you generate it ?

First, I run obj-mtl-importer.py on my .obj file in pvpython which generates .pvsm state file and .json file along with .vtp files. Next, I have also tried apply-materials.py by running it in ParaView and applying applyMaterialToRepresentation(’/path/to/representations.json’) function.
Furthermore, I have tried editing .pvsm state file and manually adding absolute paths. Now I don’t see errors on import but there is nothing in the viewer but changes its color to white.
Please refer to the image below.

EDIT:
If I apply some filter on the imported file, then it shows me 3D object in the viewer but without texture. If I change coloring option from the properties panel to TextureCoordinates, it shows me magnitude color and not the original color/texture of the object.

So I guess this is a @jourdain question

Thank you very much @mwestphal for your attention. I hope someone will help me out with this.
