Mind sharing the .blend you are trying to export from?

I get these error while exporting to glTF format, but when I copy the mesh object to a new file and export it works.

Can confirm if I have the Selected Objects option ON and there are objects in a collection which is excluded from the view layer

The exporter checks .select_get() here [which throws the error for objects not in the view layer]

if export_settings[gltf2_blender_export_keys.SELECTED] and blender_object.select_get() is False:

@JulienDuroure: mind checking?

I can confirm.

We already have issues in upstream repo that are linked to this issue :

@JulienDuroure :not 100% sure about this, and I am not sure how this suites design of the exporter, but instead of going over scene.objects (like in __gather_scene) you could use code from https://docs.blender.org/api/master/bpy.types.Depsgraph.html#dependency-graph-simple-exporter to get selected stuff to export safely (just a thought...)?

Exactly same problem I want to emphasize that I choose an option Selection Only.
This problem is also found in addons when you trying to export selected object. Instant Meshes Remesh as an example.
