The find API for this movie:

curl --location 'https://api.themoviedb.org/3/find/tt1001328?api_key={APIkey}&language=en-US&external_source=imdb_id&append_to_response=images' \
--header 'Connection: keep-alive' \
--header 'Accept: application/json, text/plain, */*' \
--header 'Content-Type: image/jpeg'

returns empty:

{
    "movie_results": [],
    "person_results": [],
    "tv_results": [],
    "tv_episode_results": [],
    "tv_season_results": [],
    "images": {
        "movie_results": [],
        "person_results": [],
        "tv_results": [],
        "tv_episode_results": [],
        "tv_season_results": []
    }
}

Is there no content or is my query incorrect?

Thanks, Henry
