Hello. I created a simple scene in Blender provided here as a zip file.

When I attempt to use the gltf_auto_export plugin for Blender, I get the following error every time I save:

failed to export gltf ! Converting py args to operator properties:: keyword "export_colors" unrecognized

I have found that if I use your provided example blend files, I do not get this error and the expected gltf is produced. This is very likely to be user error but it is very unclear what my mistake is. Could someone expand on what's going on here?

Information about my system: system-info.txt That file does not make it clear that I am running Blender from a Flatpak.

I see that you're using Blender 4.2. I had the same issue, switching to 3.6 fixed it for me. Notably, I had a different (but similar) issue on 3.0, too.

Bumping as I also have this issue.

Updating to say that ARP 3.72.39 seems to have fixed it.
