Same error, I am also getting in blender 4.0 while exporting datasmith file with textures.

Problem solved, you can older version 3.1.0 then add on will work.

Using Blender 4.1 here. I changed and commented out some parts of the scripts to get it to export successfully. Changed the method to read normals to m.corner_normals. Commented out lines where they're trying to read specular and transmission, cause I Found out that the way blender reads and stores specular and transmission/opacity changed after 4.0. Don't know what's the correct way to edit these lines so I just commented them out and I'm able to export as datasmith successfully.
