Good evening - I'm using propertygraph index - I'm making the entities and relations manually and inserting them with upsert_nodes/upsert_relations - basically the same as the example in the docs.
I'm noticing these nodes/relations don't get any embedding and when making a query, they're all scored at 0. I've tried calculaing the embedding manually for the EntityNodes but am still getting 0 scores. Is there something fundamental I am missing?
