It could have something to do with mongoose not allowing you to use the $ operator more than once per key. Check out using the DocumentArray.id(id) method to search subdocuments. Check out Noam El's answer to this question. It might help you out to do a findById() on the outermost document before using the above method.

Hope this helps point you in the right direction!
