Philipp Oeser (lichtwerk) triaged this task as Needs Information from User priority.

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.

Philipp Oeser (lichtwerk) raised the priority of this task from Needs Information from User to Confirmed, Medium.

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:

@Julien DUROURE (julien): mind checking?

@Julien DUROURE (julien) :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 to get selected stuff to export safely (just a thought...)?

@Philipp Oeser (lichtwerk) Thanks for the link, I definitively have a deeper look into it

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.
