How to find by foreign id?

Question

I try to get a result by themovidb API with a thetvdb ID
I'm not sure what I'm doin wrong

Documentation

My try to access the API

http://api.themoviedb.org/3/find/71663?api_key=XXX

My result

{"status_code":6,"status_message":"Invalid id - The pre-requisite id is invalid or not found"}

ID 71663 on thetvdb
I'm pretty sure I get this working before - but this time I can't figure out whats wrong. I think I'm missing something that defines that I'm looking for a TV show.

You have to specify the ?external_source parameter
