This is the first time I use blender and whatever I try to export anything to i3d this is the message that I get at the end of a log, I've tried fixing this for hours to no avail, How do I fix this?

Here is the rest of the log:

I believe this is because Blender 4.1.0 changed something. If you switch back to an earlier Blender version like 4.0.0, it will probably work. Or you can wait for me to merge #205, which I believe is a fix for this :-)
