Please help tell me what I'm doing wrong :) (no results for Tom Hanks)

curl -X POST -H "Content-Type: application/json" -d '{"image_url":"https://www.gstatic.com/tv/thumb/persons/62982/62982_v9_bb.jpg"}' http://localhost:5000/search

I'm executing the above command against the latest git master project.

it returns:
{"links": [], "descriptions": [], "titles": [], "similar_images": [], "best_guess": ""}

But if I put that into google image search it works fine.
