The code that outputs the error message.

ExtractedClusterableObjectElement::Light(entity)

    if let Some(clusterable_object_index) =
          global_clusterable_object_meta.entity_to_index.get(entity)

        {
            warn!(

                 objects in the view are present in too many clusters."

            break;
        }
        view_clusters_bindings.push_index(*clusterable_object_index);
    } else {
        // This should never happen. The appropriate systems
        // should have populated
        // `global_clusterable_object_meta` by now.
        error!(
            "Clustered light or decal {:?} had no assigned index!",
            entity
        );
        view_clusters_bindings.push_dummy_index();
    }
}

I’m not sure what’s going on here, especially since the comment states "This should never happen." I noticed @pcwalton has been working in this area recently, so maybe could take a look?

It seems that global_clusterable_object_meta is not being populated correctly, as entity_to_index is empty.
