Can't attach skeletal mesh to component

I have the following BP set up to attach a mesh component to a tracked controller component. It works well.

However, when I try to do the same thing with a skeletal mesh, I can’t seem to get it working. I have my Physics Asset joints set to the same collision settings as the previous mesh. Any ideas?

For troubleshooting sake: so joints function the same as collision boxes on regular meshes? Is there a way to add a collision box to a skeletal mesh?

Is there a setting in the skeleton setup that would prevent attach the skeleton to a scene component?

Thanks!
